Abstract
Valvular heart disease affects 30% of the new-borns with congenital heart disease. Valve replacement of semilunar valves by mechanical, bioprosthetic or donor allograft valves is the main treatment approach. However, none of the replacements provides a viable valve that can grow and/or adapt with the growth of the child leading to re-operation throughout life. In this study, we review the impact of donor valve preservation on moving towards a more viable valve alternative for valve replacements in children or young adults.

Abstract
Right ventricular fibrosis is a stress response, predominantly mediated by cardiac fibroblasts. This cell population is sensitive to increased levels of pro-inflammatory cytokines, pro-fibrotic growth factors and mechanical stimulation. Activation of fibroblasts results in the induction of various molecular signaling pathways, most notably the mitogen-activated protein kinase cassettes, leading to increased synthesis and remodeling of the extracellular matrix. While fibrosis confers structural protection in response to damage induced by ischemia or (pressure and volume) overload, it simultaneously contributes to increased myocardial stiffness and right ventricular dysfunction. Here, we review state-of-the-art knowledge of the development of right ventricular fibrosis in response to pressure overload and provide an overview of all published preclinical and clinical studies in which right ventricular fibrosis was targeted to improve cardiac function.

Introduction
Cardiovascular diseases (CVDs) are the number one cause of mortality among non-communicable diseases. Two mechanisms of cardiac remodelling after injury have been hypothesized. In the early phases, remodelling is caused by cardiomyocytes (CMs) death, while later it is due to the attempts at reconstruction from the surviving myocardium. Due to the inability of cardiomyocytes to divide, the adult mammalian heart has negligible endogenous regenerative capacity, and the injured myocardium heals through formation of a scar, while surviving CMs become hypertrophic. These mechanisms can lead to progressive left ventricular dilatation, loss of contractility and transition to heart failure. With significant effort from the research community, new therapies to treat cardiac injury are being investigated, with particular attention to regenerative cellular therapies.
Purpose
The aim of this study is to devise therapies able to target CMs to eventually replenish the heart of contractile units by inducing CMs proliferation.
Methods
Atrial appendage or ventricle wall samples were derived from the surgical waste material of adult patients who underwent heart surgery for heart valve disease and/or Morrow myectomy. Cardiac-resident mesenchymal progenitor cells and endothelial cells were derived and amplified from the atrial samples, while organotypic cardiac slices (thickness 300 um) were obtained by cutting the ventricular samples with a vibratome and then cultured at a liquid-air interface. Functionality was proven by viability staining and biochemical assays. Cells and slices were treated with compounds aimed to improve cell health (dexamethasone or SB-431542) and/or vectors carrying reporters (Fiber-modified HAdV vectors or nanoparticles enveloped in a lipid membrane).
Results
Human myocardial slices were viable up to 7 days in culture without electrical or mechanical stimulation. During this time in control conditions there was collagen deposition and onset of fibrosis. Treatment with dexamethasone (100 nM) prevented loss of collagen structure and activation of markers of cardiac remodelling. The specific inhibition of the remodelling marker Smad-3 with SB-431542 didn’t have any evident effect on the viability and structural integrity of the slices. Vectors HadV-5 and HadV-11 had highly efficient transduction in monolayers of human cells peaking around 48h, but low efficiency in myocardial slices. Nanoparticles had efficient transduction in monolayers of cells and myocardial slices, but shorter particle lifespan (<48h).
Conclusions
We established a quick and simple method for the preparation of vital tissue slices from human adult ventricular myocardium as well as their preservation in culture. This model represents a novel platform for testing vectors targeting CMs in a 3-D environment, highlighting the differences in transduction efficiency when compared to standard monolayer culture techniques.

Abstract
Abstract
Background
The heart is covered by the epicardium, consisting of epithelial cells and a mesenchymal layer. The epicardium has been shown to be essential during cardiac development by contributing cells through epithelial-to-mesenchymal transition (EMT) and the secretion of paracrine factors. In the adult, the epicardium conveys a cardioprotective response after myocardial infarction, albeit suboptimal compared to the epicardial contribution to heart development. Although the developing epicardium has been characterised in mice and zebrafish, knowledge on the human fetal epicardium derives mostly from cell culture models. Therefore, direct analysis of the human fetal epicardium is vital as it provides new insights into the cellular and biochemical interactions within the developing heart, which can potentially contribute to enhancing the post-injury response.
Aim
To study the human fetal epicardium using single-cell RNA sequencing (scRNA seq) in order to determine its cellular composition. The data are further explored to e.g. identify regulators of epicardial EMT.
Methods
Epicardial layers were isolated from four fetal human hearts (14–15 weeks gestation, obtained under informed consent and according to local ethical approval). Tissue was digested, and single live cells were sorted into 384-wells plates and sequenced. Data analysis was performed using R-packages RaceID3 and StemID2. Findings were validated using qPCR and immunohistochemistry.
Results
Analysis of 2073 cells reveals a clear clustering of the epicardial epithelium and the mesenchymal population. Importantly, we found that “classical” markers, such as Wilms' Tumor 1 and T-box transcription factor 18, are not specific enough to reliably identify the epicardium, but our analysis has provided markers that do allow for robust identification of the epicardium. Additionally, we were able to identify epicardial subpopulations based on their expression profile and validated these using immunohistochemistry in human fetal and adult heart tissue sections. To establish the regulation of epicardial activation we are focussing on the process of EMT within our dataset using RaceID2. From our analysis, several regulators of epicardial EMT are proposed that will be followed up on in vitro.
Conclusions
We identify various novel markers of the fetal epithelial epicardium, as well as characterizing markers of the mesenchymal layer. We also identified novel factors involved in epicardial EMT, and these are currently being validated in our cell-culture model. These data can provide new insights into the post-injury response in the adult heart.

Abstract
Pulmonary endarterectomy (PEA) resected material offers a unique opportunity to develop an in vitro endothelial cell model of chronic thromboembolic pulmonary hypertension (CTEPH). We aimed to comprehensively analyze the endothelial function, molecular signature, and mitochondrial profile of CTEPH-derived endothelial cells to better understand the pathophysiological mechanisms of endothelial dysfunction behind CTEPH, and to identify potential novel targets for the prevention and treatment of the disease. Isolated cells from specimens obtained at PEA (CTEPH-EC), were characterized based on morphology, phenotype, and functional analyses (in vitro and in vivo tubule formation, proliferation, apoptosis, and migration). Mitochondrial content, morphology, and dynamics, as well as high-resolution respirometry and oxidative stress, were also studied. CTEPH-EC displayed a hyperproliferative phenotype with an increase expression of adhesion molecules and a decreased apoptosis, eNOS activity, migration capacity and reduced angiogenic capacity in vitro and in vivo compared to healthy endothelial cells. CTEPH-EC presented altered mitochondrial dynamics, increased mitochondrial respiration and an unbalanced production of reactive oxygen species and antioxidants. Our study is the foremost comprehensive investigation of CTEPH-EC. Modulation of redox, mitochondrial homeostasis and adhesion molecule overexpression arise as novel targets and biomarkers in CTEPH.

Abstract
Abstract
Background
The epicardium, the outer layer of the heart, is an indispensable source of cells and paracrine factors during embryonic heart formation. In the adult heart, the epicardium is quiescent unless there is injury. Cardiac damage results in partial recapitulation of developmental processes including epithelial-to-mesenchymal transition (EMT), expression of Wilms' Tumor-1 (WT1), proliferation, and migration of epicardial-derived cells (EPDCs).
Aim
Given their vital role during development, EPDCs represent an appealing source for endogenous cardiovascular repair. However, EPDC contribution to cardiac tissue formation in the adult is less efficient than during embryonic development. Our aim is to determine the requirements to optimize the adult epicardial response to injury.
Methods
Human foetal and adult EPDCs were isolated from cardiac specimens and cultured as epithelial-like cells in the presence of an Alk5-kinase inhibitor (A5ki). EMT was induced by adding 1 ng/mL TGFβ for 5 days. Immunofluorescent staining, qPCR, and cytokine arrays were performed. Cultured adult EPDCs pre- and post-EMT were transplanted into the myocardial wall of NOD-SCID mice after inducing myocardial infarction (MI), and cardiac function was measured by high-frequency ultrasound. Hearts were histologically analysed 3 days and 6 weeks post-MI.
Results
Both foetal and adult human EPDCs can be expanded in culture and undergo EMT after TGFβ stimulation leading to morphological changes accompanied by downregulation of WT1 and E-cadherin, and upregulation of mesenchymal genes. Importantly, upon removal of Alk5ki, foetal EPDCs display instant spontaneous EMT, suggesting the importance of this process for EPDCs' developmental potential.
In vivo, animals receiving intramyocardial transplantation of post-EMT EPDCs displayed a higher ejection fraction 6 weeks after MI compared to pre-EMT EPDC receiving animals (26%±11 n=8 vs. 11%±5 n=9 respectively P<0.05). This corresponded to a smaller infarct size in the post-EMT group (16,4%±4 of the left ventricle versus 26,9%±5 in pre-EMT, p<0.05). This could not be explained by a difference in cell grafting, analysed at 3 days post-MI. After 6 weeks, we observed a small difference in human collagen deposition in the post-EMT group, however very low numbers of human cells were detected suggesting a predominantly short-acting paracrine effect. Analysis of cytokine production of cultured cells revealed a higher production of factors involved in angiogenesis and chemotaxis like VEGF and MCP-3 in post-EMT EPDCs in comparison to pre-EMT EPDCs. Effects on local angiogenesis and inflammation in vivo are being investigated
Conclusion
EPDCs require EMT to acquire the ability to contribute to cardiac repair, which appears to be predominantly through paracrine processes. Our research now focuses on enhancing EMT of endogenous epicardial cells.

Abstract
RATIONALE BMP9 (bone morphogenetic protein 9) is a circulating endothelial quiescence factor with protective effects in pulmonary arterial hypertension (PAH). Loss-of-function mutations in BMP9, its receptors, and downstream effectors have been reported in heritable PAH. OBJECTIVES To determine how an acquired deficiency of BMP9 signaling might contribute to PAH. METHODS Plasma levels of BMP9 and antagonist soluble endoglin were measured in group 1 PAH, group 2 and 3 pulmonary hypertension (PH), and in patients with severe liver disease without PAH. MEASUREMENTS AND MAIN RESULTS BMP9 levels were markedly lower in portopulmonary hypertension (PoPH) versus healthy control subjects, or other etiologies of PAH or PH; distinguished PoPH from patients with liver disease without PAH; and were an independent predictor of transplant-free survival. BMP9 levels were decreased in mice with PH associated with CCl4-induced portal hypertension and liver cirrhosis, but were normal in other rodent models of PH. Administration of ALK1-Fc, a BMP9 ligand trap consisting of the activin receptor-like kinase-1 extracellular domain, exacerbated PH and pulmonary vascular remodeling in mice treated with hypoxia versus hypoxia alone. CONCLUSIONS BMP9 is a sensitive and specific biomarker of PoPH, predicting transplant-free survival and the presence of PAH in liver disease. In rodent models, acquired deficiency of BMP9 signaling can predispose to or exacerbate PH, providing a possible mechanistic link between PoPH and heritable PAH. These findings describe a novel experimental model of severe PH that provides insight into the synergy between pulmonary vascular injury and diminished BMP9 signaling in the pathogenesis of PAH.

Abstract
Cell transdifferentiation occurs during cardiovascular development or remodeling either as a pathologic feature in the progression of disease or as a response to injury. Endothelial-to-Mesenchymal Transition (EndMT) is a process that is classified as a specialized form of Epithelial-to-Mesenchymal Transition (EMT), in which epithelial cells lose their epithelial characteristics and gain a mesenchymal phenotype. During transdifferentiation, cells lose both cell-cell contacts and their attachment to the basement membrane. Subsequently, the shape of the cells changes from a cuboidal to an elongated shape. A rearrangement of actin filaments facilitates the cells to become motile and prime their migration into the underlying tissue. EMT is a key process during embryonic development, wound healing and tissue regeneration, but has also been implicated in pathophysiological processes, such organ fibrosis and tumor metastases. EndMT has been associated with additional pathophysiological processes in cardiovascular related diseases, including atherosclerosis. Recent studies prove a significant role for EndMT in the progression and destabilization of atherosclerotic plaques, as a consequence of EndMT-derived fibroblast infiltration and the increased secretion of matrix metalloproteinase respectively. In this review we will discuss the essential molecular and morphological mechanisms of EMT and EndMT, along with their common denominators and key differences. Finally, we will discuss the role of EMT/EndMT in developmental and pathophysiological processes, focusing on the potential role of EndMT in atherosclerosis in more depth.

Abstract
e16576 Background: Prostate cancer is the second most common cancer in men worldwide. Lethality is normally associated with the consequences of metastasis rather than the primary tumor. In particular, bone is the most frequent site of metastasis and once prostate tumor cells are engrafted in the skeleton, curative therapy is no longer possible. Bone morphogenetic proteins (BMPs) play a critical role in bone physiology and pathology. However, little is known about the role of BMP9 and its signaling receptors, ALK1 and ALK2, in prostate cancer and bone metastasis. In this context, we investigate the impact of BMP9 on primary prostate cancer and derived bone metastasis. Methods: The human ALK1 extracellular domain (ECD) binds BMP9 and BMP10 with high affinity. In order to study the effect of BMP9 in vitro and in vivo we use a soluble chimeric protein, consisting of ALK1 ECD fused to human Fc (ALK1Fc), for preventing the activation of endogenous signaling. ALK1Fc sequesters BMP9 and BMP10, preserving the activation of ALK1 through other ligands. Results: We show that ALK1Fc reduces BMP9-mediated signaling and decreases proliferation of highly metastatic and tumor initiating human prostate cancer cells in vitro. In line with these observations, we demonstrate that ALK1Fc reduces tumor growth in vivo in an orthotopic transplantation model. The propensity of the primary prostate cancer to metastasize to the bone is also investigated. In particular, we report how the ALK1Fc influences the prostate cancer cells in vitro and in vivo when these are probed in different bone settings (co-culture with bone cells and intraosseous transplantation in mice). Conclusions: Our study provides the first demonstration that ALK1Fc inhibits prostate cancer cells growth identifying BMP9 as a putative therapeutic target and ALK1Fc as a potential therapy. All together, these findings justify the ongoing clinical development of drugs blocking ALK1 and ALK2 receptor activity.

Abstract
BACKGROUND Advancing structural and functional maturation of stem cell-derived cardiomyocytes remains a key challenge for applications in disease modeling, drug screening, and heart repair. Here, we sought to advance cardiomyocyte maturation in engineered human myocardium (EHM) toward an adult phenotype under defined conditions. METHODS We systematically investigated cell composition, matrix, and media conditions to generate EHM from embryonic and induced pluripotent stem cell-derived cardiomyocytes and fibroblasts with organotypic functionality under serum-free conditions. We used morphological, functional, and transcriptome analyses to benchmark maturation of EHM. RESULTS EHM demonstrated important structural and functional properties of postnatal myocardium, including: (1) rod-shaped cardiomyocytes with M bands assembled as a functional syncytium; (2) systolic twitch forces at a similar level as observed in bona fide postnatal myocardium; (3) a positive force-frequency response; (4) inotropic responses to β-adrenergic stimulation mediated via canonical β1- and β2-adrenoceptor signaling pathways; and (5) evidence for advanced molecular maturation by transcriptome profiling. EHM responded to chronic catecholamine toxicity with contractile dysfunction, cardiomyocyte hypertrophy, cardiomyocyte death, and N-terminal pro B-type natriuretic peptide release; all are classical hallmarks of heart failure. In addition, we demonstrate the scalability of EHM according to anticipated clinical demands for cardiac repair. CONCLUSIONS We provide proof-of-concept for a universally applicable technology for the engineering of macroscale human myocardium for disease modeling and heart repair from embryonic and induced pluripotent stem cell-derived cardiomyocytes under defined, serum-free conditions.

Abstract
Transforming growth factor-β (TGF-β) is a multifunctional cytokine with important roles in embryogenesis and maintaining tissue homeostasis during adult life. There are three isoforms of TGF-β, i.e., TGF-β1, -β2, and -β3, which signal by binding to a complex of transmembrane type I and type II serine/threonine kinase receptors and intracellular Smad transcription factors. In most cell types TGF-β signals via TGF-β type II receptor (TβRII) and TβRI, also termed activin receptor-like kinase 5 (ALK5). In endothelial cells, TGF-β signals via ALK5 and ALK1. These two type I receptors mediate opposite cellular response for TGF-β. The co-receptor endoglin, highly expressed on proliferating endothelial cells, facilitates TGF-β/ALK1 and inhibits TGF-β/ALK5 signaling. Knockout of TGF-β receptors in mice all result in embryonic lethality during midgestation from defects in angiogenesis, illustrating the pivotal role of TGF-β in this process. This chapter introduces methods for examining the function and regulation of TGF-β in angiogenesis in in vitro assays using cultured endothelial cells and ex vivo metatarsal explants.

Abstract
Background Aneurysms affecting the aorta are a common condition associated with high mortality as a result of aortic dissection or rupture. Investigations of the pathogenic mechanisms involved in syndromic types of thoracic aortic aneurysms, such as Marfan and Loeys-Dietz syndromes, have revealed an important contribution of disturbed transforming growth factor (TGF)-β signaling. Objectives This study sought to discover a novel gene causing syndromic aortic aneurysms in order to unravel the underlying pathogenesis. Methods We combined genome-wide linkage analysis, exome sequencing, and candidate gene Sanger sequencing in a total of 470 index cases with thoracic aortic aneurysms. Extensive cardiological examination, including physical examination, electrocardiography, and transthoracic echocardiography was performed. In adults, imaging of the entire aorta using computed tomography or magnetic resonance imaging was done. Results Here, we report on 43 patients from 11 families with syndromic presentations of aortic aneurysms caused by TGFB3 mutations. We demonstrate that TGFB3 mutations are associated with significant cardiovascular involvement, including thoracic/abdominal aortic aneurysm and dissection, and mitral valve disease. Other systemic features overlap clinically with Loeys-Dietz, Shprintzen-Goldberg, and Marfan syndromes, including cleft palate, bifid uvula, skeletal overgrowth, cervical spine instability and clubfoot deformity. In line with previous observations in aortic wall tissues of patients with mutations in effectors of TGF-β signaling (TGFBR1/2, SMAD3, and TGFB2), we confirm a paradoxical up-regulation of both canonical and noncanonical TGF-β signaling in association with up-regulation of the expression of TGF-β ligands. Conclusions Our findings emphasize the broad clinical variability associated with TGFB3 mutations and highlight the importance of early recognition of the disease because of high cardiovascular risk.

Abstract
RATIONALE RNA-binding proteins are critical post-transcriptional regulators of RNA and can influence pre-mRNA splicing, RNA localization, and stability. The RNA-binding protein Quaking (QKI) is essential for embryonic blood vessel development. However, the role of QKI in the adult vasculature, and in particular in vascular smooth muscle cells (VSMCs), is currently unknown. OBJECTIVE We sought to determine the role of QKI in regulating adult VSMC function and plasticity. METHODS AND RESULTS We identified that QKI is highly expressed by neointimal VSMCs of human coronary restenotic lesions, but not in healthy vessels. In a mouse model of vascular injury, we observed reduced neointima hyperplasia in Quaking viable mice, which have decreased QKI expression. Concordantly, abrogation of QKI attenuated fibroproliferative properties of VSMCs, while potently inducing contractile apparatus protein expression, rendering noncontractile VSMCs with the capacity to contract. We identified that QKI localizes to the spliceosome, where it interacts with the myocardin pre-mRNA and regulates the splicing of alternative exon 2a. This post-transcriptional event impacts the Myocd_v3/Myocd_v1 mRNA balance and can be modulated by mutating the quaking response element in exon 2a of myocardin. Furthermore, we identified that arterial damage triggers myocardin alternative splicing and is tightly coupled with changes in the expression levels of distinct QKI isoforms. CONCLUSIONS We propose that QKI is a central regulator of VSMC phenotypic plasticity and that intervention in QKI activity can ameliorate pathogenic, fibroproliferative responses to vascular injury.

Abstract
In response to vascular injury, smooth muscle cells (VSMC) adopt a proliferative, synthetic hypocontractile phenotype. This phenotype switch is deemed instrumental in vascular remodeling in both health and disease. Here, we detail a decisive role for the RNA-binding protein Quaking (QKI) in regulating VSMC plasticity. We identified that the RNA-binding protein Quaking (QKI) is highly expressed by neointimal VSMCs of human coronary restenotic lesions, but not in healthy vessels. In a mouse model of vascular injury, we observed reduced neointima hyperplasia in Qk
v
mice, which have decreased QKI expression. Concordantly, abrogation of QKI attenuated fibroproliferative properties of VSMCs, while potently inducing contractile apparatus protein expression, rendering non-contractile VSMCs with the capacity to contract. We identified that QKI localizes to the spliceosome in proliferative VSMCs, where it interacts with and impacts myocardin (pre)-mRNA metabolism by mediating myocardin exon 2a exclusion. As such, in vitro and in vivo experiments indicate that the modulation of QKI expression directly influences the myocardin_v3 / myocardin_v1 mRNA balance, which could play a role in shifting the Myocardin-induced transcriptional coactivation profile following arterial damage. We propose that QKI is a central regulator of VSMC phenotypic plasticity and that intervention in QKI activity can ameliorate pathogenic, fibroproliferative responses to vascular injury.

Abstract
Transforming growth factor-beta (TGF-β) stimulates both ischaemia induced angiogenesis and shear stress induced arteriogenesis by signalling through different receptors. How these receptors are involved in both these processes of blood flow recovery is not entirely clear. In this study the role of TGF-β receptors 1 and endoglin is assessed in neovascularization in mice. Unilateral femoral artery ligation was performed in mice heterozygous for either endoglin or ALK1 and in littermate controls. Compared with littermate controls, blood flow recovery, monitored by laser Doppler perfusion imaging, was significantly hampered by maximal 40% in endoglin heterozygous mice and by maximal 49% in ALK1 heterozygous mice. Collateral artery size was significantly reduced in endoglin heterozygous mice compared with controls but not in ALK1 heterozygous mice. Capillary density in ischaemic calf muscles was unaffected, but capillaries from endoglin and ALK1 heterozygous mice were significantly larger when compared with controls. To provide mechanistic evidence for the differential role of endoglin and ALK1 in shear induced or ischaemia induced neovascularization, murine endothelial cells were exposed to shear stress in vitro. This induced increased levels of endoglin mRNA but not ALK1. In this study it is demonstrated that both endoglin and ALK1 facilitate blood flow recovery. Importantly, endoglin contributes to both shear induced collateral artery growth and to ischaemia induced angiogenesis, whereas ALK1 is only involved in ischaemia induced angiogenesis.

Abstract
The importance of the epicardium covering the heart and the intrapericardial part of the great arteries has reached a new summit. It has evolved as a major cellular component with impact both in development, disease and more recently also repair potential. The role of the epicardium in development, its differentiation from a proepicardial organ at the venous pole (vPEO) and the differentiation capacities of the vPEO initiating cardiac epicardium (cEP) into epicardium derived cells (EPDCs) have been extensively described in recent reviews on growth and transcription factor pathways. In short, the epicardium is the source of the interstitial, the annulus fibrosus and the adventitial fibroblasts, and differentiates into the coronary arterial smooth muscle cells. Furthermore, EPDCs induce growth of the compact myocardium and differentiation of the Purkinje fibers. This review includes an arterial pole located PEO (aPEO) that provides the epicardium covering the intrapericardial great vessels. In avian and mouse models disturbance of epicardial outgrowth and maturation leads to a broad spectrum of cardiac anomalies with main focus on non-compaction of the myocardium, deficient annulus fibrosis, valve malformations and coronary artery abnormalities. The discovery that in disease both arterial and cardiac epicardium can again differentiate into EPDCs and thus reactivate its embryonic program and potential has highly broadened the scope of research interest. This reactivation is seen after myocardial infarction and also in aneurysm formation of the ascending aorta. Use of EPDCs for cell therapy show their positive function in paracrine mediated repair processes which can be additive when combined with the cardiac progenitor stem cells that probably share the same embryonic origin with EPDCs. Research into the many cell-autonomous and cell-cell-based capacities of the adult epicardium will open up new realistic therapeutic avenues.

Abstract
Rationale:
Since their discovery almost 20 years ago, microRNAs have been shown to perform essential roles during tissue development and disease. Although roles for microRNAs in the myocardium during embryo development and cardiac disease have been demonstrated, very little is know about their role in the endocardium or during cardiac valve formation.
Objective:
To study the role of microRNAs in cardiac valve formation.
Methods and Results:
We show that zebrafish
dicer
mutant embryos, lacking mature miRNAs, form excessive endocardial cushions. By screening miRNAs expressed in the heart, we found that miR-23 is both necessary and sufficient for restricting the number of endocardial cells that differentiate into endocardial cushion cells. In addition, in mouse endothelial cells, miR-23 inhibited a transforming growth factor-β–induced endothelial-to-mesenchymal transition. By in silico screening of expression data with predicted miR-23 target sites combined with in vivo testing, we identified hyaluronic acid synthase 2 (
Has2)
,
Icat
, and
Tmem2
as novel direct targets of miR-23. Finally, we demonstrate that the upregulation of
Has2
, an extracellular remodeling enzyme required for endocardial cushion and valve formation, is responsible for the excessive endocardial cushion cell differentiation in
dicer
mutants.
Conclusions:
MiR-23 in the embryonic heart is required to restrict endocardial cushion formation by inhibiting
Has2
expression and extracellular hyaluronic acid production.

Abstract
Recent studies suggest that the therapeutic effects of stem cell transplantation following myocardial infarction (MI) are mediated by paracrine factors. One of the main goals in the treatment of ischemic heart disease is to stimulate vascular repair mechanisms. Here, we sought to explore the therapeutic angiogenic potential of mesenchymal stem cell (MSC) secretions. Human MSC secretions were collected as conditioned medium (MSC-CM) using a clinically compliant protocol. Based on proteomic and pathway analysis of MSC-CM, an in vitro assay of HUVEC spheroids was performed identifying the angiogenic properties of MSC-CM. Subsequently, pigs were subjected to surgical left circumflex coronary artery ligation and randomized to intravenous MSC-CM treatment or non-CM (NCM) treatment for 7 days. Three weeks after MI, myocardial capillary density was higher in pigs treated with MSC-CM (645 ± 114 vs 981 ± 55 capillaries/mm(2); P = 0.021), which was accompanied by reduced myocardial infarct size and preserved systolic and diastolic performance. Intravenous MSC-CM treatment after myocardial infarction increases capillary density and preserves cardiac function, probably by increasing myocardial perfusion.

Abstract
Background Diabetic patients experience exaggerated intimal hyperplasia after endovascular procedures. Recently it has been shown that circulating smooth muscle progenitor cells (SPC) contribute to intimal hyperplasia. We hypothesized that SPC differentiation would be increased in diabetes and focused on modulation of TGF-β/BMP-6 signaling as potential underlying mechanism. Methods We isolated SPC from C57Bl/6 mice with streptozotocin-induced diabetes and controls. SPC differentiation was evaluated by immunofluorescent staining for αSMA and collagen Type I. SPC mRNA expression of TGF-β and BMP-6 was quantified using real-time PCR. Intima formation was assessed in cuffed femoral arteries. Homing of bone marrow derived cells to cuffed arterial segments was evaluated in animals transplanted with bone marrow from GFP-transgenic mice. Results We observed that SPC differentiation was accelerated and numeric outgrowth increased in diabetic animals (24.6 ± 8.8 vs 8.3 ± 1.9 per HPF after 10 days, p < 0.05). Quantitative real-time PCR showed increased expression of TGF-β and decreased expression of the BMP-6 in diabetic SPC. SPC were MAC-3 positive, indicative of monocytic lineage. Intima formation in cuffed arterial segments was increased in diabetic mice (intima/media ratio 0.68 ± 0.15 vs 0.29 ± 0.06, p < 0.05). In GFP-chimeric mice, bone marrow derived cells were observed in the neointima (4.4 ± 3.3 cells per section) and particularly in the adventitia (43.6 ± 9.3 cells per section). GFP-positive cells were in part MAC-3 positive, but rarely expressed α-SMA. Conclusions In conclusion, in a diabetic mouse model, SPC levels are increased and SPC TGF-β/BMP-6 expression is modulated. Altered TGF-β/BMP-6 expression is known to regulate smooth muscle cell differentiation and may facilitate SPC differentiation. This may contribute to exaggerated intimal hyperplasia in diabetes as bone marrow derived cells home to sites of neointima formation.

Abstract
Myocardial infarction is the major cause of death in western countries due to impaired function of the heart, which is the result of cardiomyocyte death and fibrotic scar formation. The endogenous regenerative capacity of the heart is unable to replenish this significant loss of tissue and conventional medical management cannot correct the underlying defects in cardiac muscle cell number. Recently, tremendous effort is being put into the development of cell transplantation protocol for heart repair, which has been put forward as an alternative therapy to reduce cell damage, cardiomyocyte death and improve tissue contraction. Unfortunately the ideal stem cell population for heart repair has not been identified to date, but several characteristics are defined which the ideal population should have namely, reduce cell damage, reduce cardiomyocyte death, induce differentiation into cardiomyocytes and endothelial cells, and improve tissue contraction. It is unclear whether this will be possible in one optimal population. Therefore the research focus is shifting towards improving the characteristics of the stem cell populations that are identified to date. In this review, we will give an overview of the different stem/progenitor cell populations and their application in cardiac repair and discuss current knowledge on issues like differentiation capacity, paracrine secretion profile, genetic modification of progenitor cells and their influence on cardiac remodeling.

Abstract
BACKGROUND Adult human epicardium-derived cells (EPDCs), transplanted into the infarcted heart, are known to improve cardiac function, mainly through paracrine protection of the surrounding tissue. We hypothesized that this effect might be further improved if these supportive EPDCs were combined with cells that could possibly supply the ischemic heart with new cardiomyocytes. Therefore, we transplanted EPDCs together with cardiomyocyte progenitor cells that can generate mature cardiomyocytes in vitro. METHODS AND RESULTS EPDCs and cardiomyocyte progenitor cells were isolated from human adult atrial appendages, expanded in culture, and transplanted separately or together into the infarcted mouse myocardium (total cell number, 4x10(5)). Cardiac function was determined 6 weeks later (9.4T MRI). Coculturing increased proliferation rate and production of several growth factors, indicating a mutual effect. Cotransplantation resulted in further improvement of cardiac function compared with single cell-type recipients (P<0.05), which themselves demonstrated better function than vehicle-injected controls (P<0.05). However, in contrast to our hypothesis, no graft-derived cardiomyocytes were observed within the 6-week survival, supporting that not only EPDCs but also cardiomyocyte progenitor cells acted in a paracrine manner. Because injected cell number and degree of engraftment were similar between groups, the additional functional improvement in the cotransplantation group cannot be explained by an increased amount of secreted factors but rather by an altered type of secretion. CONCLUSIONS EPDCs and cardiomyocyte progenitor cells synergistically improve cardiac function after myocardial infarction, probably instigated by complementary paracrine actions. Our results demonstrate for the first time that synergistically acting cells hold great promise for future clinical regeneration therapy.

Abstract
Cell-based cardiac repair has the ambitious aim to replace the malfunctioning cardiac muscle developed after myocardial infarction, with new contractile cardiomyocytes and vessels. Different stem cell populations have been intensively studied in the last decade as a potential source of new cardiomyocytes to ameliorate the injured myocardium, compensate for the loss of ventricular mass and contractility and eventually restore cardiac function. An array of cell types has been explored in this respect, including skeletal muscle, bone marrow derived stem cells, embryonic stem cells (ESC) and more recently cardiac progenitor cells. The best-studied cell types are mouse and human ESC cells, which have undisputedly been demonstrated to differentiate into cardiomyocyte and vascular lineages and have been of great help to understand the differentiation process of pluripotent cells. However, due to their immunogenicity, risk of tumor development and the ethical challenge arising from their embryonic origin, they do not provide a suitable cell source for a regenerative therapy approach. A better option, overcoming ethical and allogenicity problems, seems to be provided by bone marrow derived cells and by the recently identified cardiac precursors. This report will overview current knowledge on these different cell types and their application in cardiac regeneration and address issues like implementation of delivery methods, including tissue engineering approaches that need to be developed alongside.

Abstract
Gradually the distinction between signalling pathways originally believed to be specific for either hypertrophy, cell cycle control, apoptosis and cell survival are fading. The subtle variations in stimuli to a cell and the microenvironment will determine cell fate. In cardiomyocytes the entrance into the cell cycle is efficiently blocked. Therefore attention has focused on pathways involved in hypertrophy to assess effects in ischaemic models and vice versa. Interventions at different levels have been shown to be cardiomyocyte protective. Various growth factors (including IGF1 and FGF1,2) have shown to prevent or delay cardiomyocyte loss in and ex vivo. Similar results have been reported for downstream interventions in the signalling pathways. Strong effects after MAPK activation have been shown in gene targeted mice. Especially constitutive activation of the ERK proteins prevents ischemic damage of the heart with conservation of left ventricular function. Evidence for a key role of nuclear Akt in preventing apoptosis is accumulating from various genetic and pharmacological sources. Development of techniques to measure the level of cardiomyocyte death depends on further improvements in molecular imaging in mouse and human. In addition to studying cardiomyocyte cell death, it is crucial to measure myocardial function. Whether hypertrophy following ischaemia is adaptive or maladaptive and whether all apoptosis is detrimental will have to be determined by assessment of left ventricular function through invasive and noninvasive methods.

Abstract
The use of stem cells for cardiac repair is a promising opportunity for developing new treatment strategies as the applications are theoretically unlimited and lead to actual cardiac tissue regeneration. Human embryonic stem cells were only recently cloned and their capacity to differentiate into true cardiomyocytes makes them in principle an unlimited source of transplantable cells for cardiac repair, although practical and ethical constraints exist. Also, the study of embryonic stem cells and their differentiation into cardiomyocytes will bring forth new insights into the molecular processes involved in cardiomyocyte-development and -proliferation, which could lead to the development of other strategies to augment in vivo cardiomyocyte numbers. On the other hand, somatic stem cells are alternative cell sources that can be used for cell transplantation purposes. They do not evoke ethical issues and bear less ethical constraints. However, they also appear to be much more restricted in their differentiation potential than the embryonic stem cells. Here we discuss the use of both cell types, embryonic and somatic stem cells, in relation with their importance for the clarification of cardiomyocyte-development and their possible usefulness for clinical therapy.

Abstract
Of the various growth factors involved in the healing response after a fracture, bone morphogenetic proteins (BMPs) are emerging as key modulators. BMPs exert their effects by binding to a complex of type I and type II receptors leading to the phosphorylation of specific downstream effector proteins called Smads. The current study examined the presence of BMP signaling components in human callus obtained from five nascent malunions undergoing fracture fixation. These callus samples represented various stages of bone healing and a mixture of endochondral and intramembraneous bone healing. We performed immunohistochemistry on the callus, using antibodies for BMP (BMP-2,-3,-4,-7), their receptors (BMPR-IA, -IB, -II), and phosphorylated BMP receptor-regulated Smads (pBMP-R-Smads). Active osteoblasts showed fairly consistent positive staining for all BMPs that were examined, with the immunoreactivity most intense for BMP-7 and BMP-3. Immunostaining for BMPs in osteoblasts appeared to colocalize with the expression of BMPR-IA, -IB, and -II. Positive immunostaining for pBMP-R-Smads suggests that the BMP receptors expressed in these cells are activated. Staining for BMPs in cartilage cells was variable. The immunostaining appeared stronger in more mature cells, whereas staining for BMP receptors in cartilage cells was less ubiquitous. However, the expression of pBMP-R-Smads in cartilage cells suggests active signal transduction. Fibroblast-like cells also had a variable staining pattern. Overall, our findings indicate the presence of BMPs, their various receptors, and activated forms of receptor-regulated Smads in human fracture callus. To the best of our knowledge, this is the first study that documents the expression of these proteins in human fracture tissue. Complete elucidation of the roles of BMP in bone formation will hopefully lead to improved fracture healing care.

Abstract
Smads are pivotal intracellular nuclear effectors of transforming growth factor-beta (TGF-beta) family members. Ligand-induced activation of TGF-beta family receptors with intrinsic serine/threonine kinase activity trigger phosphorylation of receptor-regulated Smads (R-Smads), whereas Smad2 and Smad3 are phosphorylated by TGF-beta, and activin type I receptors, Smad1, Smad5 and Smad8, act downstream of BMP type I receptors. Activated R-Smads form heteromeric complexes with common-partner Smads (Co-Smads), e.g. Smad4, which translocate efficiently to the nucleus, where they regulate, in co-operation with other transcription factors, coactivators and corepressors, the transcription of target genes. Inhibitory Smads act in most cases in an opposite manner from R- and Co-Smads. Like other components in the TGF-beta family signaling cascade, Smad activity is intricately regulated. The multifunctional and context dependency of TGF-beta family responses are reflected in the function of Smads as signal integrators. Certain Smads are somatically mutated at high frequency in particular types of human cancers. Gene ablation of Smads in the mouse has revealed their critical roles during embryonic development. Here we review the latest advances in our understanding of the Smad mechanism of action and their in vivo functions.

Abstract
TSC-22 is a highly conserved member of a novel family of transcription factors, that is a direct target of transforming growth factor-beta (TGF-beta) in osteoblastic cells. We have investigated the expression of TSC-22 in detail during mouse development using in situ hybridization. We detected strong expression of TSC-22 in the embryo proper first at embryonic day 8.5 (E8.5), in the primitive heart, intermediate mesoderm and the neural tube. The dynamics of the TSC-22 distribution in the neural tube was particularly striking, with ubiquitous expression rostrally and restriction to neural tissue nearer the floor plate more caudally; between E8.5 and E9.5 the zone of restricted expression extended rostrally. At later stages of development, TSC-22 was detected in the mesenchymal compartment of many tissues and organs, including the lung, trachea, kidney, stomach, intestine, tooth buds, and in precartilage condensations. Furthermore, TSC-22 was highly expressed in the floor plate itself and notochord, and the endothelium lining the blood vessels, in particular the major arteries. Many of these sites have been proposed previously as possible TGF-beta target tissues; the results imply that TSC-22 may also be a direct TGF-beta target gene during mouse embryogenesis. Experiments on TSC-22 expression in embryoid bodies of embryonic stem (ES) cells expressing dominant negative TGF-beta binding receptors initially supported this hypothesis. However, examination of somatic chimeras derived from these same mutant ES cells at nominal E9.5 showed that TSC-22 expression in the heart and neural tube was still detectable despite obvious phenotypic abnormalities. We therefore propose that although TSC-22 may be a direct target of TGF-beta in late development, other factors are likely to be major regulators of expression at earlier stages.

Abstract
SMAD proteins are downstream targets of serine/threonine kinase receptors of the transforming growth factor beta (TGF beta) superfamily. Ligands activating these receptors regulate cell growth, differentiation and development in many tissues of various organisms. In mammals eight different Smad genes are known, each with different roles in mediating signalling between plasma membrane and nucleus. Smad6 and Smad7 are inhibitors of TGF beta family signalling. They are both expressed in human adult vascular endothelial cells, particularly after these cells have been subjected to shear stress (Topper et al. [1997] Proc Natl Acad Sci USA 94:9314-9319). Here we show by reverse transcriptase polymerase chain reaction and in situ hybridization that Smad7 mRNA is highly expressed in the developing vascular system of the mouse embryo but is also detectable much earlier in preimplantation embryos and during gastrulation. We also demonstrate by transient transgenesis that overexpression of Smad7 in mouse zygotes inhibits development beyond the 2-cell stage. This confirms earlier conclusions of similar, but complementary, experiments using a dominant negative type II TGF beta receptor demonstrating that TGF beta signalling is required for normal preimplantation development.

Abstract
During recent years, our understanding of TGFbeta signalling through serine/threonine kinase receptors and Smads has increased enormously. Activation of R-Smads by receptor induced phosphorylation is followed by complex formation with co-Smads and translocation to the nucleus, where the transcription of specific genes is affected and ultimately results in changes in cell behaviour. Experimental analysis primarily of epithelial cells in culture has revealed that a number of members of the TGFbeta family are interchangeable in the effect they have on growth and differentiation. On the other hand, different ligands of the TGFbeta superfamily can result in different responses because of cell type specific expression of other components of the signalling pathway. The relative expression levels of receptors and Smads within the cell is an important determinant of TGFbeta induced responses. Functional analysis of genes in the TGFbeta superfamily signal transduction cascade in vivo in mice either lacking entire genes, or expressing dominant negative forms of particular proteins, are providing profound new insights into the signalling cascades, their interaction and their specificity (Table 3). For example, by phenotypical comparison and intercrossing different heterozygous mutants, it has become clear that nodal, until recently an orphan protein without receptor/signal complex, probably signals through the activin type II receptor, ALK-4 and Smad2 (Nomura and Li, 1998; Song et al., 1999). Many of the genes of this cascade that have been targeted in the mouse result in early embryonic lethal phenotypes, demonstrating an important function for the BMP and TGFbeta/activin-activated pathways in mesoderm formation and differentiation, but masking a possible role in later events. For example mutations in BMP2 and 4 are lethal at or soon after gastrulation so that their putative role in skeletogenesis cannot be studied in mice lacking these genes. The difference in severity of the phenotypes between ligand, receptor and Smad deficient mice suggest that other receptors and ligands may partially compensate for the loss of one protein. Chimeric analysis provides one tool for analysing later developmental functions. By rescuing the early defects it was demonstrated that TGFbeta family members have an important function in anterior development and left/right asymmetry. Temporal and spatial specific gene targeting will be a powerful tool for analysing the function of TGFbeta family members in for example, bone formation, angiogenesis and carcinogenesis. Isolation of cells from the different gene targeted mice provides a unique source of material to gain more insight in the biochemical mechanisms of specific pathways. For example, use of cells deficient in Smad2 for biochemical and cell biological assays could give a better view of the function of Smad3. Smad3 deficient mice already demonstrate that there is a clear difference between Smad2 and Smad3 during development. Full descriptions of the remaining gene ablation studies of this signal transduction cascade, namely those for ALK-5, BMPR-II and Smad1 and -7 are eagerly awaited to complete the puzzle. As more of these superfamily of ligands and their signalling pathways have been functionally dissected, it has become evident that this superfamily of growth factors plays a pivotal role in epiblast formation and gastrulation, signalling from both the epiblast as well as the extraembryonic tissues. Furthermore, it becomes clear that TGFbeta is indeed important for proper vessel formation and that it might use endoglin, as well as ALK-1, ALK-5 and Smad5 to mediate this function. Further analyses of these mice should provide a clearer understanding of the mechanism of TGFbeta action in vascular development and remodelling.

Abstract
We have analysed the function of transforming growth factor beta (TGF-beta) in yolk sac development in mice by generating somatic chimaeras in which the extraembryonic mesoderm, which gives rise to the endothelial and haematopoietic cells of the yolk sac vasculature, is derived from embryonic stem (ES) cells. The ES cells were stably transfected and express either the full-length type II binding receptor or a kinase-deficient mutant of this receptor. Examination of yolk sacs from chimaeras between E8.5 and 9.5, and analysis of marker expression in embryoid bodies from these mutant ES cell lines in prolonged suspension culture demonstrated that (1) a major function of TGF-beta in yolk sac mesoderm is to regulate production and deposition of fibronectin in the extracellular matrix that maintains yolk sac integrity, (2) TGF-beta signalling is not required for differentiation of extraembryonic mesoderm into endothelial cells but is necessary for their subsequent organisation into robust vessels, and (3) TGF-beta signalling must be tightly regulated for the differentiation of primitive haematopoietic cells to take place normally. Together, these results show that defective TGF-beta signalling in the extraembryonic mesoderm alone is sufficient to account for the extraembryonic phenotype reported previously in TGF-beta1(−/−) mice (Dickson, M. C., Martin, J. S., Cousins, F. M., Kulkarni, A. B., Karlsson, S. and Akhurst, R. J. (1995) Development 121, 1845–1854).

Abstract
Mouse embryonic stem (ES) cells grown in aggregates give rise to several different cell types, including cardiac muscle. Given the lack of cardiac muscle cell lines, ES cells can be a useful tool in the study of cardiac muscle differentiation. The laminin-binding integrin alpha 6 beta 1 exists in two different splice variant forms of the alpha chain (alpha 6A and alpha 6B), the alpha 6A form having been implicated as possibly playing a role in cardiac muscle development, based on its distribution pattern [4, 53]. In this study we characterise the ES cell model system in terms of the expression of the two different alpha 6 splice variants. We correlate their expression with that of muscle markers and the transcription factor GATA-4, using the reverse transcription-polymerase chain reaction (RT-PCR). We confirm that alpha 6B is constitutively expressed by ES cells. In contrast, alpha 6A expression appears later and overlaps in time with a period when the muscle marker myosin light chain-2V (MLC-2V) is expressed, but no MyoD is present, which indicates the presence of cardiac muscle cells in the aggregates. We further show that GATA-4 is present at the same time. Culturing the aggregates under conditions that stimulate (transforming growth factor beta 1 supplement) or inhibit (TGF beta 1 plus 10(-9) M retinoic acid supplement) cardiac muscle differentiation does not lead to any qualitative differences in the timing of expression of these genes, but quantitative changes cannot be excluded. The TGF beta 1 supplement does, however, lead to a relatively greater expression of alpha 6A compared to alpha 6B than the TGF beta 1 plus 10(-9) M RA supplement after 6 days in culture, suggesting that alpha 6A expression is favoured under conditions that stimulate cardiac muscle differentiation. The switch towards alpha 6A expression in ES cell aggregates is paralleled by expression of the binding receptor for TGF beta (T beta RII). Stable expression of a mutated (dominant negative) T beta RII in ES cells, however, still resulted in (TGF beta-independent) upregulation of alpha 6A, demonstrating that these events were not causally related and that parallel or alternative regulatory pathways exist. The initial characterisation of differentiating ES cell aggregates in terms of alpha 6A integrin subunit expression suggests that this model system could be a valuable tool in the study of the role of the alpha 6A beta 1 integrin in cardiac muscle differentiation.

Abstract
Transforming growth factor beta (TGFbeta) regulates the cell cycle and extracellular matrix (ECM) deposition of many cells in vitro. We have analysed chimaeric mouse embryos generated from embryonic stem cells with abnormal receptor expression to study the effect of TGFbeta on these processes in vivo and the consequences for normal development. The binding receptor for TGFbeta, TbetaRII, is first detected in the embryo proper around day 8.5 in the heart. Ectopic expression of TbetaRII from the blastocyst stage onward resulted in an embryonic lethal around 9.5 dpc. Analysis of earlier stages revealed that the primitive streak of TbetaRII chimaeras failed to elongate. Furthermore, although cells passed through the streak and initially formed mesoderm, they tended to accumulate within the streak. These defects temporally and spatially paralleled the expression of the TGFbeta type I receptor, which is first expressed in the node and primitive streak. We present evidence that classical TGFbeta-induced growth inhibition was probably the cause of insufficient mesoderm being available for paraxial and axial structures. The results demonstrate that (1) TGFbeta mRNA and protein detected previously in early postimplantation embryos is present as a biologically active ligand; and (2) assuming that ectopic expression of TbetaRII results in no other changes in ES cells, the absence of TbetaRII is the principle reason why the embryo proper is unresponsive to TGFbeta ligand until after gastrulation.

Abstract
In this study the function of transforming growth factor-beta (TGF-beta) in preimplantation mouse embryos was examined. By RT-PCR, mRNA for the signalling type I (T beta R-I) and type II (T beta R-II) receptors for TGF-beta was shown to be present in two distinct time windows: in fertilized oocytes and at the blastocyst stage. The function of TGF-beta at these times was analysed in two ways. Firstly, the TGF-beta signalling pathway was blocked by injecting a DNA construct encoding a truncated T beta R-II, that acts as a dominant-negative receptor, in fertilized oocytes, and the effect on development was determined. Secondly, inner cell masses isolated at the blastocyst stage were cultured in vitro with and without TGF-beta under conditions that favour the outgrowth of parietal endoderm. The results show that TGF-beta signalling mediated by maternally expressed receptors is important for development of preimplantation embryos beyond the two-cell stage, and suggest a regulatory role for TGF-beta in the outgrowth of parietal endoderm.

Abstract
Embryonic stem (ES) cells are resistant to transforming growth factor beta (TGF beta). We have shown previously that they lack type-II binding receptors (T beta RII) and in this respect resemble the inner cell mass and ectoderm cells of mouse embryos 4.5-7.5 days post coitum (dpc); they do however express type-I (alk-5) signalling receptors. Here we show that in contrast to several tumour cell lines, stable transfection of wtT beta RII is not sufficient for ES cells to become biologically sensitive to TGF beta. We analysed the expression of several down-stream molecules known to be involved in TGF beta signalling (Smads) and TGF beta-mediated cell cycle regulation (cyclins D) during the differentiation of control and wtT beta RII-expressing ES cells and showed that upregulation of these molecules correlated with (i) an increase in plasminogen activator inhibitor-1 (PAI-1) synthesis and (ii) growth inhibition, following addition of TGF beta 1. These TGF beta responses were reduced in an ES cell line expressing a dominant negative (truncated) T beta RII (delta T beta RII). The differentiation pattern of control and wtT beta RII-expressing ES cells was indistinguishable in monolayer culture and as embryoid bodies, but in delta T beta RII ES cells, the capacity to form mesodermal derivatives in monolayer cultures in response to the addition of retinoic acid (RA) and removal of leukemia inhibitory factor (LIF) was lost, and only endoderm-like cells formed. The T beta RII and delta T beta RII ES cells were, however, both distinguishable from control ES cells when allowed to differentiate in chimaeric embryos following aggregation with morula-stage hosts. Conceptuses containing mutant cells, recovered from pseudopregnant females at the equivalent of 9.5 dpc, exhibited highly defective yolk sac development; most strikingly, no blood vessels were present and in addition the yolk sacs with derivatives of ES cells containing wtT beta RII were blistered and lacked haematopoietic cells. The implications for understanding TGF beta signalling in early mouse development are discussed.

Abstract
The beta1D integrin is a recently characterized isoform of the beta1 subunit that is specifically expressed in heart and skeletal muscle. In this study we have assessed the function of the beta1D integrin splice variant in mice by generating, for the first time, Cre-mediated exon-specific knockout and knockin strains for this splice variant. We show that removal of the exon for beta1D leads to a mildly disturbed heart phenotype, whereas replacement of beta1A by beta1D results in embryonic lethality with a plethora of developmental defects, in part caused by the abnormal migration of neuroepithelial cells. Our data demonstrate that the splice variants A and D are not functionally equivalent. We propose that beta1D is less efficient than beta1A in mediating the signaling that regulates cell motility and responses of the cells to mechanical stress.

Abstract
Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-beta family of polypeptide signaling molecules. They function via binding to two types of transmembrane serine/threonine kinase receptors, type I and type II receptors, that are both necessary for signaling. The expression patterns of the type II BMP receptor (BMPR-II) and three type I BMP receptors (ActR-I, BMPR-IA and BMPR-IB) were examined in preimplantation embryos by means of heminested reverse transcription-polymerase chain reaction (RT-PCR). BMPR-II mRNA was detected in one-cell, two-cell and blastocyst stage embryos. ActR-I exhibited a similar expression pattern. BMPR-IA mRNA however was only detected in blastocysts, whereas BMPR-IB transcripts were detected at all stages from the one-cell zygote to the uncompacted morula, but not in the compacted morula and blastocyst. If translated into proteins, this suggests that different receptor complexes can be formed at different developmental stages. Transcripts for BMPs were not detected in preimplantation embryos, but were detected in the maternal tissues surrounding the embryos. BMPR-II, BMPR-IA and BMPR-IB mRNAs were also detected in undifferentiated and differentiated embryonal carcinoma and embryonic stem cells. In postimplantation embryos BMPR-II transcripts were first detected from 6.0 days post coitum. In situ hybridization analysis revealed that BMPR-II mRNA is ubiquitously expressed in the entire embryo at least until midgestation.
