Abstract
The regeneration of the osteochondral unit represents a challenge due to the distinct cartilage and bone phases. Current strategies focus on the development of multiphasic scaffolds that recapitulate features of this complex unit and promote the differentiation of implanted bone-marrow derived stem cells (BMSCs). In doing so, challenges remain from the loss of stemness during in vitro expansion of the cells and the low control over stem cell activity at the interface with scaffolds in vitro and in vivo. Here, this work scaffolds inspired by the bone marrow niche that can recapitulate the natural healing process after injury. The construct comprises an internal depot of quiescent BMSCs, mimicking the bone marrow cavity, and an electrospun (ESP) capsule that "activates" the cells to migrate into an outer "differentiation-inducing" 3D printed unit functionalized with TGF-β and BMP-2 peptides. In vitro, niche-inspired scaffolds retained a depot of nonproliferative cells capable of migrating and proliferating through the ESP capsule. Invasion of the 3D printed cavity results in location-specific cell differentiation, mineralization, secretion of alkaline phosphatase (ALP) and glycosaminoglycans (GAGs), and genetic upregulation of collagen II and collagen I. In vivo, niche-inspired scaffolds are biocompatible, promoted tissue formation in rat subcutaneous models, and regeneration of the osteochondral unit in rabbit models.

Abstract
Autologous cell therapy (ACT) is a new therapeutic approach for diabetic patients with no-option chronic limb-threatening ischemia (NO-CLTI). The aim of our study was to quantify cell populations of cell therapy products (CTPs) obtained by three different isolation methods and to correlate their numbers with changes in transcutaneous oxygen pressure (TcPO2). CTPs were separated either from stimulated peripheral blood (PB) (n = 11) or harvested from bone marrow (BM) processed either by Harvest SmartPReP2 (n = 50) or sedimented with succinate gelatin (n = 29). The clinical effect was evaluated by the change in TcPO2 after 1, 3 and 6 months. TcPO2 increased significantly in all three methods at each time point in comparison with baseline values (p < .01) with no significant difference among them. There was no correlation between the change in TcPO2 and the size of injected cell populations. We only observed a weak correlation between the number of injected white blood cells (WBC) and an increase in TcPO2 at 1 and 3 months. Our study showed that all three isolation methods of ACT were similarly relatively efficient in the treatment of NO-CLTI. We observed no correlation of TcPO2 increase with the number of injected monocytes, lymphocytes or CD34+. We observed a weak correlation between TcPO2 increase and the number of injected WBCs.

Abstract
Deregulation of angiogenesis is a key reason for tumor growth and progression. Several anti-angiogenic drugs in clinical practice attempt to normalize abnormal tumor vasculature. Unfortunately, these drugs are ineffective due to the development of resistance in patients after drug holidays. A sizable literature suggests that resistance to these anti-angiogenic drugs occurs due to various compensatory mechanisms of tumor angiogenesis. Therefore, we describe different compensatory mechanisms of tumor angiogenesis, and explain why intussusceptive angiogenesis (IA), is a crucial mechanism of compensatory angiogenesis in tumors which resist anti-VEGF (vascular endothelial growth factor) therapies. IA is often overlooked due to the scarcity of experimental models. Therefore, we examine data from existing experimental models and our novel ex-ovo model of angiogenesis in chick embryos, and explain the important genes and signaling pathways driving IA. Using bio-informatic analyses of major genes regulating conventional sprouting angiogenesis (SA) and intussusceptive angiogenesis, we provide fresh insights on the 'angiogenic switch' which regulates the transition from SA to IA. Finally, we examine the interplay between molecules regulating SA, IA, and molecules known to promote tumor progression. Based on these analyses, we conclude that intussusceptive angiogenesis (IA) is a promising therapeutic target for developing effective anti-cancer treatment regimes.

Abstract
Renal cell carcinoma (RCC) is highly dependent on angiogenesis, due to the overactivation of the VHL/HIF/VEGF/VEGFRs axis; this justifies the marked sensitivity of this neoplasm to antiangiogenic agents which, however, ultimately fail to control tumor growth. RCC also frequently shows alterations in the mTOR signaling pathway, and mTOR inhibitors have shown a similar pattern of initial activity/late failure as pure antiangiogenic agents. Understanding mechanisms of resistance to these agents would be key to improve the outcome of our patients. Circulating endothelial cells are a family of mainly bone marrow-derived progenitors, which have been postulated to be responsible of the reactivation of angiogenesis in different tumors. In this review, we shall discuss the complex nature and function of these cells, the evidence pro and contra their contribution to tumor vascularization, especially as far as RCC is concerned, and their possible role in determining resistance to presently available treatments.

Abstract
BACKGROUND AIMS During bone formation, angiogenesis and osteogenesis are regulated by hypoxia, which is able to induce blood vessel formation, as well as recruit and differentiate human mesenchymal stromal cells (hMSCs). The molecular mechanisms involved in HIF-1α response and hMSC differentiation during bone formation are still unclear. This study aimed to investigate the synergistic role of hypoxia and hypoxia-mimetic microRNA miR-675-5p in angiogenesis response and osteo-chondroblast commitment of hMSCs. METHODS By using a suitable in vitro cell model of hMSCs (maintained in hypoxia or normoxia), the role of HIF-1α and miR-675-5p in angiogenesis and osteogenesis coupling was investigated, using fluorescence-activated cell sorting (FACS), gene expression and protein analysis. RESULTS Hypoxia induced miR-675-5p expression and a hypoxia-angiogenic response, as demonstrated by increase in vascular endothelial growth factor messenger RNA and protein release. MiR-675-5p overexpression in normoxia promoted the down-regulation of MSC markers and the up-regulation of osteoblast and chondroblast markers, as demonstrated by FACS and protein analysis. Moreover, miR-675-5p depletion in a low-oxygen condition partially abolished the hypoxic response, including angiogenesis, and in particular restored the MSC phenotype, demonstrated by cytofluorimetric analysis. In addition, current preliminary data suggest that the expression of miR-675-5p during hypoxia plays an additive role in sustaining Wnt/β-catenin pathways and the related commitment of hMSCs during bone ossification. DISCUSSION MiR-675-5p may trigger complex molecular mechanisms that promote hMSC osteoblastic differentiation through a dual strategy: increasing HIF-1α response and activating Wnt/β-catenin signaling.

Abstract
Endothelial progenitor cells (EPCs) are a sub-population of bone marrow-derived mononuclear cells that are released in circulation to restore damaged endothelium during its physiological turnover or rescue blood perfusion after an ischemic insult. Additionally, they may be mobilized from perivascular niches located within larger arteries' wall in response to hypoxic conditions. For this reason, EPCs have been regarded as an effective tool to promote revascularization and functional recovery of ischemic hearts, but clinical application failed to exploit the full potential of patients-derived cells. Indeed, the frequency and biological activity of EPCs are compromised in aging individuals or in subjects suffering from severe cardiovascular risk factors. Rejuvenating the reparative phenotype of autologous EPCs through a gene transfer approach has, therefore, been put forward as an alternative approach to enhance their therapeutic potential in cardiovascular patients. An increase in intracellular Ca2+ concentration constitutes a pivotal signal for the activation of the so-called endothelial colony forming cells (ECFCs), the only known truly endothelial EPC subset. Studies from our group showed that the Ca2+ toolkit differs between peripheral blood- and umbilical cord blood (UCB)-derived ECFCs. In the present article, we first discuss how VEGF uses repetitive Ca2+ spikes to regulate angiogenesis in ECFCs and outline how VEGF-induced intracellular Ca2+ oscillations differ between the two ECFC subtypes. We then hypothesize about the possibility to rejuvenate the biological activity of autologous ECFCs by transfecting the cell with the Ca2+ -permeable channel Transient Receptor Potential Canonical 3, which selectively drives the Ca2+ response to VEGF in UCB-derived ECFCs.

Abstract
Ischemic heart and cerebral diseases are complex clinical syndromes. Endothelial dysfunction caused by dysfunctional endothelial progenitor cells (EPCs) is thought to play a major role in pathophysiology of both types of disease. Healthy EPCs may be able to replace the dysfunctional endothelium through endogenous repair mechanisms. EPC levels are changed in patients with ischemic cerebrovascular and cardiovascular disease and EPCs may play a role in the pathophysiology of these diseases. EPCs are also a marker for preventive and therapeutic interventions. Homing of EPCs to ischemic sites is a mechanism of ischemic tissue repair, and molecules such as stromal-derived factor-1 and integrin may play a role in EPC homing in ischemic disease. Potentiation of the function and numbers of EPCs as well as combining EPCs with other pharmaceutical agents may improve the condition of ischemia patients. However, the precise role of EPCs in ischemic heart and cerebral disease and their therapeutic potential still remain to be explored. Here, we discuss the identification, mobilization, and clinical implications of EPCs in ischemic diseases.

Abstract
For repair of chronic or difficult-to-heal tissue lesions and defects, major constraints exist to a broad application of cell therapy and tissue engineering approaches, i.e., transplantation of “ex vivo” expanded autologous stem/progenitor cells, alone or associated with carrier biomaterials. To enable a large number of patients to benefit, new strategies should be considered. One of the main goals of contemporary regenerative medicine is to develop new regenerative therapies, inspired from Mother Nature. In all injured tissues, when platelets are activated by tissue contact, their released factors promote innate immune cell migration to the wound site. Platelet-derived factors and factors secreted by migrating immune cells create an inflammatory microenvironment, in turn, causing the activation of angiogenesis and vasculogenesis processes. Eventually, repair or regeneration of the injured tissue occurs via paracrine signals activating, mobilizing or recruiting to the wound site cells with healing potential, such as stem cells, progenitors, or undifferentiated cells derived from the reprogramming of tissue differentiated cells. This review, largely based on our studies, discusses the identification of new tools, inspired by cellular and molecular mechanisms overseeing physiological tissue healing, that could reactivate dormant endogenous regeneration mechanisms lost during evolution and ontogenesis.

Abstract
BACKGROUND Bone marrow mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs) are used to repair hypoxic or ischemic tissue. However, the underlining mechanism of resistance in the hypoxic microenvironment and the efficacy of migration to the injured tissue are still unknown. The current study aims to understand the hypoxia resistance and migration ability of MSCs during differentiation toward endothelial lineages by biochemical and mechanical stimuli. METHOD MSCs were harvested from the bone marrow of 6-8-week-old Sprague-Dawley rats. The endothelial growth medium (EGM) was added to MSCs for 3 days to initiate endothelial differentiation. Laminar shear stress was used as the fluid mechanical stimulation. RESULTS Application of EGM facilitated the early endothelial lineage cells (eELCs) to express EPC markers. When treating the hypoxic mimetic desferrioxamine, both MSCs and eELCs showed resistance to hypoxia as compared with the occurrence of apoptosis in rat fibroblasts. The eELCs under hypoxia increased the wound closure and C-X-C chemokine receptor type 4 (CXCR4) gene expression. Although the shear stress promoted eELC maturation and aligned cells parallel to the flow direction, their migration ability was not superior to that of eELCs either under normoxia or hypoxia. The eELCs showed higher protein expressions of CXCR4, phosphorylated Akt (pAkt), and endogenous NFκB and IκBα than MSCs under both normoxia and hypoxia conditions. The potential migratory signals were discovered by inhibiting either Akt or NFκB using specific inhibitors and revealed decreases of wound closure and transmigration ability in eELCs. CONCLUSION The Akt and NFκB pathways are important to regulate the early endothelial differentiation and its migratory ability under a hypoxic microenvironment.

Abstract
Diabetes is associated with impaired mobilization of bone marrow stem/progenitor cells that accelerate vascularization of ischemic areas. This study characterized mobilization of vascular reparative bone marrow progenitor cells in mouse models of diabetes. Age-matched control or streptozotocin (STZ)-induced diabetic, and db/db mice with lean-controls were studied. Mobilization induced by G-CSF, AMD3100 or ischemia was evaluated by flow cytometric enumeration of circulating Lin(-)Sca-1(+)cKit(+) (LSK) cells, and by colony forming unit (CFU) assay. The circulating WBCs and LSKs, and CFUs were reduced in both models with a shorter duration (10-12 weeks) of diabetes compared to their respective controls. Longer duration of STZ-diabetes (≥20 weeks) induced impairment of G-CSF- or AMD3100-mobilization (P < 0.01, n = 8). In db/db mice, mobilization by G-CSF or AMD3100 was either increased or unaffected (P < 0.05, n = 6 to 8). Proliferation, migration, and ischemia-induced mobilization, of LSK cells were impaired in both models. Leptin receptor antagonist, PESLAN-1, increased G-CSF- or AMD3100-mobilization of WBCs and LSKs, compared to the untreated. Leptin increased basal WBCs, decreased basal and AMD3100-mobilized LSK cells, and had no effect on G-CSF. These results suggest that mobilopathy is apparent in STZ-diabetes but not in db/db mice. Leptin receptor antagonism would be a promising approach for reversing diabetic bone marrow mobilopathy.

Non-Hematopoietic Essential Functions of Bone Marrow Cells: A Review of Scientific and Clinical Literature and Rationale for Treating Bone Defects. Orthop Rev (Pavia) 2015; 7:5691. [PMID: 26793290 PMCID: PMC4703908 DOI: 10.4081/or.2015.5691] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2014] [Accepted: 10/20/2015] [Indexed: 01/13/2023] Open
Abstract
Hematopoiesis as the only essential function of bone marrow cells has been challenged for several decades through basic science (in vitro and in vivo) and clinical data. Such work has shed light on two other essential functions of bone marrow cells: osteopoiesis and angio-genesis/vasculogenesis. Clinical utility of autologous concentrated bone marrow aspirate (CBMA) has demonstrated both safety and efficacy in treating bone defects. Moreover, CBMA has been shown to be comparable to the gold standard of iliac crest bone graft (ICBG), or autograft, with regard to being osteogenic and osteoinductive. ICBG is not considered an advanced therapy medicinal product (ATMP), but CBMA may become regulated as an ATMP. The European Medicines Agency Committee for Advanced Therapies (EMA:CAT) has issued a reflection paper (20 June 2014) in which reversal of the 2013 ruling that CBMA is a non-ATMP has been proposed. We review bone marrow cell involvement in osteopoiesis and angiogenesis/vasculogenesis to examine EMA:CAT 2013 decision to use CBMA for treatment of osteonecrosis (e.g, of the femoral head) should be considered a non-ATMP. This paper is intended to provide discussion on the 20 June 2014 reflection paper by reviewing two non-hematopoietic essential functions of bone marrow cells. Additionally, we provide clinical and scientific rationale for treating osteonecrosis with CBMA.

Abstract
Neonatal hypoxic-ischemic (HI) brain injuries disrupt the integrity of neurovascular structure and lead to lifelong neurological deficit. The devastating damage can be ameliorated by preserving the endothelial network, but the source for therapeutic cells is limited. We aim to evaluate the beneficial effect of mechanical shear stress in the differentiation of endothelial lineage cells (ELCs) from adipose-derived stem cells (ASCs) and the possible intracellular signals to protect HI injury using cell-based therapy in the neonatal rats. The ASCs expressed early endothelial markers after biochemical stimulation of endothelial growth medium. The ELCs with full endothelial characteristics were accomplished after a subsequential shear stress application for 24 hours. When comparing the therapeutic potential of ASCs and ELCs, the ELCs treatment significantly reduced the infarction area and preserved neurovascular architecture in HI injured brain. The transplanted ELCs can migrate and engraft into the brain tissue, especially in vessels, where they promoted the angiogenesis. The activation of Akt by neuropilin 1 (NRP1) and vascular endothelial growth factor receptor 2 (VEGFR2) was important for ELC migration and following in vivo therapeutic outcomes. Therefore, the current study demonstrated importance of mechanical factor in stem cell differentiation and showed promising protection of brain from HI injury using ELCs treatment.

Abstract
The recruitment and homing of circulating bone marrow-derived cells include endothelial progenitor cells (EPCs) that are critical to neovascularization and tissue regeneration of various vascular pathologies. We report here that conditional inactivation of hypoxia-inducible factor's (HIF) transcriptional activity in the endothelium of adult mice (Arnt(ΔiEC) mice) results in a disturbance of infiltrating cells, a hallmark of neoangiogenesis, during the early phases of wound healing. Cutaneous biopsy punches show distinct migration of CD31(+) cells into wounds of control mice by 36 hours. However, a significant decline in numbers of infiltrating cells with immature vascular markers, as well as decreased transcript levels of genes associated with their expression and recruitment, were identified in wounds of Arnt(ΔiEC) mice. Matrigel plug assays further confirmed neoangiogenic deficiencies alongside a reduction in numbers of proangiogenic progenitor cells from bone marrow and peripheral blood samples of recombinant vascular endothelial growth factor-treated Arnt(ΔiEC) mice. In addition to HIF's autocrine requirements in endothelial cells, our data implicate that extrinsic microenvironmental cues provided by endothelial HIF are pivotal for early migration of proangiogenic cells, including those involved in wound healing.

Abstract
INTRODUCTION Angiotensin (Ang)-(1-7) is a recently identified vasoprotective heptapeptide, and it appears to activate the reparative functions of bone marrow-derived stem/progenitor cells (BMPCs). AIM This study evaluated the effect of Ang-(1-7) in the angiogenic function of cavernosum in type 1 diabetes (T1D) and delineated the role of BMPCs in this protective function. METHODS T1D was induced by streptozotocin in mice, and mice with 20-24 weeks of diabetes were used for the study. Ang-(1-7) was administered subcutaneously by using osmotic pumps. Cavernosa, and BMPCs from peripheral blood and bone marrow were evaluated in different assay systems. MAIN OUTCOME MEASURES Angiogenic function was determined by endothelial tube formation in matrigel assay. Circulating BMPCs were enumerated by flow cytometry and proliferation was determined by BrdU incorporation. Cell-free supernatant of BMPCs were collected and tested for paracrine angiogenic effect. Expression of angiogenic factors in BMPCs and cavernosa were determined by real-time polymerase chain reaction. RESULTS Ang-(1-7) (100 nM) stimulated angiogenesis in mouse cavernosum that was partially inhibited by Mas1 receptor antagonist, A779 (10 μM) (P < 0.05). In cavernosa of T1D, the angiogenic responses to Ang-(1-7) (P < 0.005) and VEGF (100 nM) (P < 0.03) were diminished. Ang-(1-7) treatment for 4 weeks reversed T1D-induced decrease in the VEGF-mediated angiogenesis. Ang-(1-7) treatment increased the circulating number of BMPCs and proliferation that were decreased in T1D (P < 0.02). Paracrine angiogenic function of BMPCs was reduced in diabetic BMPCs, which was reversed by Ang-(1-7). In diabetic BMPCs, SDF and angiopoietin-1 were upregulated by Ang-(1-7), and in cavernosum, VEGFR1, Tie-2, and SDF were upregulated and angiopoietin-2 was down-regulated. CONCLUSIONS Ang-(1-7) stimulates angiogenic function of cavernosum in diabetes via its stimulating effects on both cavernosal microvasculature and BMPCs.

Abstract
Circulating endothelial progenitor cells (EPCs) in the peripheral blood (PB) have physiological roles in the maintenance of the existing vascular beds and rescue of vascular injury. In this study, we have evaluated the properties of Lin⁻/VEGF-R2⁺ progenitor cells isolated from the mouse bone marrow (BM) and further studied their distribution and integration in an animal model of laser-induced retinal vascular injury. Lin⁻/VEGF-R2⁺ cells were enriched from C57BL/6 mice BM using magnetic cell sorting with hematopoietic lineage (Lin) depletion followed by VEGF-R2 positive selection. Lin⁻/VEGF-R2⁺ BM cells were characterized using flow cytometry and immunocytochemistry and further tested for colony formation during culture and tube formation on Matrigel®. Lin⁻/VEGF-R2⁺ BM cells possessed typical EPC properties such as forming cobble-stone shaped colonies after 3 to 4 weeks of culture, CD34⁺ expression, take up of Dil-acLDL and binding to Ulex europaeus agglutinin. However, they did not form tube-like structures on Matrigel®. The progenitor cells retained their phenotype over extended period of culture. After intravitreal transplantation in eyes subjected to the laser-induced retinal vascular injury, some Lin⁻/VEGF-R2⁺ cells were able to integrate into the damaged retinal vasculature but the level of cell integration seemed less efficient when compared with previous reports in which EPCs from the human PB were employed. Our results indicate that Lin⁻/VEGF-R2⁺ cells isolated from the mouse BM share some similarities to EPCs from the human PB but most of them are at a very early stage of maturation and remain quiescent during culture and after intravitreal transplantation.

Abstract
Endothelial progenitor cells (EPCs), which can be cultured in vitro from mononuclear cells in peripheral blood or bone marrow, express both hematopoietic stem cell and endothelial cell markers on their surface. They are believed to participate in endothelial repair and postnatal angiogenesis due to their abilities of differentiating into endothelial cells and secreting protective cytokines and growth factors. Mounting evidence suggests that circulating EPCs are reduced and dysfunctional in various diseases including hypertension, diabetes, coronary heart disease, and ischemic stroke. Therefore, EPCs have been documented to be a potential biomarker for vascular diseases and a hopeful candidate for regenerative medicine. Ischemic stroke, as the major cause of disability and death, still has limited therapeutics based on the approaches of vascular recanalization or neuronal protection. Emerging evidence indicates that transplantation of EPCs is beneficial for the recovery of ischemic cerebral injury. EPC-based therapy could open a new avenue for ischemic cerebrovascular disease. Currently, clinical trials for evaluating EPC transfusion in treating ischemic stroke are underway. In this review, we summarize the general conceptions and the characteristics of EPCs, and highlight the recent research developments on EPCs. More importantly, the rationale, perspectives, and strategies for using them to treat ischemic stroke will be discussed.

Abstract
The angiopoietins (ANGPT) are ligands for the endothelial cell (EC) receptor tyrosine kinase, Tie2. Angpt-1 is a Tie2 agonist that promotes vascular maturation and stabilization, whereas Angpt-2 is a partial agonist/antagonist involved in the initiation of postnatal angiogenesis. Therefore, we hypothesized that overexpression of Angpt-2 would be more effective than Angpt-1 for enhancing the perfusion recovery in the ischemic hindlimb. Perfusion recovery was markedly impaired in Tie2-deficient animals at day 35 in a model of chronic hindlimb ischemia. Injections of Angpt-2 or VEGFA plasmid at 7 days post femoral artery resection enhanced recovery and improved arteriogenesis as assessed by angiographic scores, whereas Angpt-1 or null plasmid had no effect. In addition, Angpt-2 together with VEGF resulted in greater improvement in perfusion and collateral vessel formation than VEGF alone. Similarly, conditional overexpression of Angpt-2 in mice improved ischemic limb blood flow recovery, while Angpt-1 overexpression was ineffective. These data from Tie2 heterozygote deficient mice demonstrate, for the first time, the importance of the Tie2 pathway in spontaneous neovascularization in response to chronic hindlimb ischemia. Moreover, they show that overexpression of the partial agonist, Angpt-2, but not Angpt-1, enhanced ischemic hind limb perfusion recovery and collateralization, suggesting that a coordinated sequence antagonist and agonist activity is required for effective therapeutic revascularization.

Abstract
Growth factors (GFs) such as BMPs, FGFs, VEGFs and IGFs have significant impacts on osteoblast behavior, and thus have been widely utilized for bone tissue regeneration. Recently, securing biological stability for a sustainable and controllable release to the target tissue has been a challenge to practical applications. This challenge has been addressed to some degree with the development of appropriate carrier materials and delivery systems. This review highlights the importance and roles of those GFs, as well as their proper administration for targeting bone regeneration. Additionally, the in vitro and in vivo performance of those GFs with or without the use of carrier systems in the repair and regeneration of bone tissue is systematically addressed. Moreover, some recent advances in the utility of the GFs, such as using fusion technology, are also reviewed.

Abstract
Cytochrome P450 4A/F (CYP4A/F) converts arachidonic acid (AA) to 20-HETE by ω-hydroxylation. The contribution of 20-HETE to the regulation of myogenic response, blood pressure, and mitogenic actions has been well summarized. This review focuses on the emerging role of 20-HETE in physiological and pathological vascularization. 20-HETE has been shown to regulate vascular smooth muscle cells (VSMC) and endothelial cells (EC) by affecting their proliferation, migration, survival, and tube formation. Furthermore, the proliferation, migration, secretion of proangiogenic molecules (such as HIF-1α, VEGF, SDF-1α), and tube formation of endothelial progenitor cells (EPC) are stimulated by 20-HETE. These effects are mediated through c-Src- and EGFR-mediated downstream signaling pathways, including MAPK and PI3K/Akt pathways, eNOS uncoupling, and NOX/ROS system activation. Therefore, the CYP4A/F-20-HETE system may be a therapeutic target for the treatment of abnormal angiogenic diseases.

Abstract
Concomitant with the extensive growth and differentiation of the mammary epithelium during pregnancy and lactation, and epithelial involution after weaning, the vasculature of the mammary gland undergoes repeated cycles of expansion and regression. Vascular expansion is effected by sprouting angiogenesis, intussusception and conceivably also vasculogenesis. The capacity of the epithelial cells to stimulate vascular growth and differentiation is dependent on the constellation of systemic and local hormones and growth factors as well as the changing demands for oxygenation and nutrient supply. This results in the release of angiogenic factors which stimulate endothelial cell growth and regulate vascular architecture. In contrast to the angiogenic phase of the mammary gland cycle, little is known about the control of vascular regression although this would possibly offer new insights into therapeutic possibilities against breast cancer. In this review we summarize knowledge regarding the mechanisms regulating the vasculature of the mammary gland and delineate the importance of the vasculature in the attainment of organ function. In addition, we discuss the angiogenic mechanisms observed during mammary carcinogenesis and their consequences for breast cancer therapy.

Abstract
OBJECTIVE Acylated ghrelin (AG) is a diabetogenic and orexigenic gastric polypeptide. These properties are not shared by the most abundant circulating form, which is unacylated (UAG). An altered UAG/AG profile together with an impairment of circulating endothelial progenitor cell (EPC) bioavailability were found in diabetes. Based on previous evidence for the beneficial cardiovascular effects of AG and UAG, we investigated their potential to revert diabetes-associated defects. RESEARCH DESIGN AND METHODS Healthy human subjects, individuals with type 2 diabetes, and ob/ob mice were AG or UAG infused. EPC mobilization in patients and mice was evaluated, and the underlying molecular mechanisms were investigated in bone marrow stromal cells. Recovered EPCs were also evaluated for the activity of senescence regulatory pathways and for NADPH oxidase activation by knocking down p47(phox) and Rac1. Finally, UAG modulation of human EPC vasculogenic potential was investigated in an in vivo mouse model. RESULTS Neither AG nor UAG had any effect in healthy subjects. However, systemic administration of UAG, but not AG, prevented diabetes-induced EPC damage by modulating the NADPH oxidase regulatory protein Rac1 and improved the vasculogenic potential both in individuals with type 2 diabetes and in ob/ob mice. In addition, unlike AG, UAG facilitated the recovery of bone marrow EPC mobilization. Crucial to EPC mobilization by UAG was the rescue of endothelial NO synthase (eNOS) phosphorylation by Akt, as UAG treatment was ineffective in eNOS knockout mice. Consistently, EPCs expressed specific UAG-binding sites, not recognized by AG. CONCLUSIONS These data provide the rationale for clinical applications of UAG in pathologic settings where AG fails.

Abstract
A growing body of evidence supports the role of redox signaling in the mechanisms of hematopoietic stem cell mobilization and homing. Cytokines and adhesion molecules control stem cell mobilization through a redox-regulated process. The FoxO–SirT network appears to be intimately involved in redox-regulated stem cell homeostasis, whereas the process of stem cell differentiation is regulated by redox effector factor-1 (Ref-1) protein. Lack of oxygen (hypoxia), specifically controlled hypoxia, can stimulate the growth of the stem cells in their niche, and hypoxia-inducible factor (HIF)-1α appears to play a significant role in their maintenance and homing mechanism.

Abstract
The skin offers a perfect model system for studying the wound healing cascade, which involves a finely tuned interplay between several cell types, pathways and processes. The dysregulation of these factors may lead to wound healing disorders resulting in chronic wounds, as well as abnormal scars such as hypertrophic and keloid scars. As the contribution of stem cells towards tissue regeneration and wound healing is increasingly appreciated, a rising number of stem cell therapies for cutaneous wounds are currently under development, encouraged by emerging preliminary findings in both animal models and human studies. However, we still lack an in-depth understanding of the underlying mechanisms through which stem cells contribute to cutaneous wound healing. The aim of this review is, therefore, to present a critical synthesis of our current understanding of the role of stem cells in normal cutaneous wound healing. In addition to summarizing wound healing principles and related key molecular and cellular players, we discuss the potential participation of different cutaneous stem cell populations in wound healing, and list corresponding stem cells markers. In summary, this review delineates current strategies, future applications, and limitations of stem cell-based or stem cell-targeted therapy in the management of acute and chronic skin wounds.

Abstract
Several epidemiologic and clinical studies have suggested that there is a strong association between hypovitaminosis D and cardiovascular disease (CVD). Hypovitaminosis D was reported as a risk factor for increased cardiovascular events among 1739 adult participants in the Framingham Offspring Study. Analysis of more than 13,000 adults in the Third National Health and Nutrition Examination Survey (NHANES III) showed that even though hypovitaminosis D is associated with an increased prevalence of CVD risk factors, its association with all-cause mortality is independent of these risk factors. Importantly, epidemiologic studies suggested that patients who had chronic kidney disease and were treated with activated vitamin D had a survival advantage when compared with those who did not receive treatment with these agents. Mechanistically, emerging data have linked vitamin D administration with improved cardiac function and reduced proteinuria, and hypovitaminosis D is associated with obesity, insulin resistance, and systemic inflammation. Preliminary studies suggested that activated vitamin D inhibits the proliferation of cardiomyoblasts by promoting cell-cycle arrest and enhances the formation of cardiomyotubes without inducing apoptosis. Activated vitamin D has also been shown to attenuate left ventricular dysfunction in animal models and humans. In summary, emerging studies suggest that hypovitaminosis D has emerged as an independent risk factor for all-cause and cardiovascular mortality, reinforcing its importance as a public health problem. There is a need to advance our understanding of the biologic pathways through which vitamin D affects cardiovascular health and to conduct prospective clinical interventions to define precisely the cardioprotective effects of nutritional vitamin D repletion.

Abstract
Endothelial progenitor cells (EPCs) were originally thought to be present only during embryonic development. New evidence suggests that they can persist into adult life, circulate in the peripheral blood and may play an important part in endothelial repair and replacement of dysfunctional endothelium. They may also play a role in the formation of new blood vessels (angiogenesis, vasculogenesis, and arteriogenesis) in ischemic tissues. In addition, EPCs have the potential to endothelialize small-diameter prosthetic vascular bypass grafts and generate a nonthrombogenic surface, thereby increasing the patency rate of these grafts. EPCs may also be used in the clinical assessment of risk of vascular disease. In this review, the authors discuss the potential use of EPCs in the management of peripheral arterial disease (PAD).

Abstract
PURPOSE The aim of this study was to determine whether the combination of 2 angiogenic growth factor, vascular endothelial growth factor 165(VEGF165) and angiopoietin-1 (Ang1), could increase angiogenesis and cardiomyocyte(CM) proliferation in an infarcted myocardium. METHODS Myocardial ischemia was induced in rats by ligation of the left anterior descending (LAD) coronary artery. Replication-deficient adenoviruses encoding VEGF165 (Ad-VEGF165), Ang1 (Ad-Ang1) or enhanced green fluorescence protein (Ad-EGFP) was injected into the ischemic myocardium immediately. Bromodexyuridine (BrdU) was administered intraperitoneally 1 week after ligation. One week later, the hearts were harvested and sectioned for hematoxylin-eosin (HE) and immunohistochemistry to evaluate densities of capillary, arteriole and double labelled BrdU(+) CM. M-mode echocardiography was used to evaluate the cardiac function. RESULTS Ang1 significantly increased collateral vessel formation. Both VEGF165 and Ang1 significantly increased densities of capillary and arteriole, as well as the number of double labelled BrdU(+) CM, and improved cardiac function. CONCLUSION Our results suggest that the combination of VEGF165 and Ang1 can increase both myocardial angiogenesis and CM proliferation following myocardial ischemia in rats, leading to improved cardiac function.

Abstract
Abstract
We recently isolated a novel angiogenesis inhibitor, vasohibin-1, and its homologue, vasohibin-2. In this study we characterize the role of these 2 molecules in the regulation of angiogenesis. In a mouse model of subcutaneous angiogenesis, the expression of endogenous vasohibin-1 was low in proliferating ECs at the sprouting front but high in nonproliferating endothelial cells (ECs) in the termination zone. In contrast, endogenous vasohibin-2 was preferentially expressed in mononuclear cells mobilized from bone marrow that infiltrated the sprouting front. When applied exogenously, vasohibin-1 inhibited angiogenesis at the sprouting front where endogenous vasohibin-1 was scarce but did not influence vascularity in the termination zone where endogenous vasohibin-1 was enriched. Exogenous vasohibin-2 prevented the termination of angiogenesis in the termination zone and increased vascularity in this region. Angiogenesis was persistent in the termination zone in the vasohibin-1 knockout mice, whereas angiogenesis was deficient at the sprouting front in the vasohibin-2 knockout mice. Supplementation of deficient proteins normalized the abnormal patterns of angiogenesis in the vasohibin knockout mice. These results indicate that vasohibin-1 is expressed in ECs in the termination zone to halt angiogenesis, whereas vasohibin-2 is expressed in infiltrating mononuclear cells in the sprouting front to promote angiogenesis.

Abstract
In this review, we highlight some of recent studies underscoring the importance of the tumor microenvironment, especially the role of bone marrow-derived myeloid cells, in restoring tumor growth after irradiation. Myeloid cells are hematopoietic cells that give rise to monocytes and macrophages in the peripheral blood and tissues. These cells have been shown to be proangiogenic in tumors promoting tumor growth. We also discuss our previously unpublished results on the effect of irradiation on the tumor vasculature including pericyte and basement membrane coverage to the endothelium of tumor blood vessels. We summarize the clinical significance of these studies including the use of MMP-9 inhibitors, administering white blood cell boosters, or planning safety margin of tumor volumes, in order to improve overall clinical benefits in cancer patients treated with radiotherapy.

Abstract
Hypovitaminosis D is an important public health problem. Serum 25-hydroxyvitamin D (25-OHD) is now recognized as an independent predictor for cardiovascular and related diseases (CVD) as well as other chronic medical conditions. However, the biologic pathways through which these effects are mediated remain poorly understood. We hypothesized that exposing mesenchymal multipotent cells (MMCs) to the active form of vitamin D would increase the expression of selected antifibrotic factors that in turn would ameliorate the progression of chronic diseases. MMCs were primed with 5'-azacytidine to induce a fibrotic phenotype and then treated with active vitamin D (1,25D) or ethanol <0.1% as vehicle in a time course manner (30 min, 1, 5, and 24 h, and for 4 and 7 days). The addition of 1,25D to MMCs promotes: a) increased expression and nuclear translocation of the vitamin D receptor; b) decreased expression of TGFB1 and plasminogen activator inhibitor (SERPINE1), two well-known profibrotic factors; c) decreased expression of collagen I, III and other collagens isoforms; and d) increased expression of several antifibrotic factors such as BMP7 a TGFB1 antagonist, MMP8 a collagen breakdown inducer and follistatin, an inhibitor of the profibrotic factor myostatin. In conclusion, the addition of 1,25D to differentiated MMCs displays a decreased profibrotic signaling pathway and gene expression, leading to decrease in collagen deposition. This study highlights key mechanistic pathways through which vitamin D decreases fibrosis, and provides a rationale for studies to test vitamin D supplementation as a preventive and/or early treatment strategy for CVD and related fibrotic disorders.

Background Prolonged psychosocial stress is a condition assessed through self-reports. Here we aimed to identify biochemical markers for screening and early intervention in women. Methods Plasma concentrations of interleukin (IL) 1-α, IL1-β, IL-2, IL-4, IL-6, IL-8, IL-10, interferon-γ (INF-γ), tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), thyroid stimulating hormone (TSH), total tri-iodothyronine (TT3), total thyroxine (TT4), prolactin, and testosterone were measured in: 195 women on long-term sick-leave for a stress-related affective disorder, 45 women at risk for professional burnout, and 84 healthy women. Results We found significantly increased levels of MCP-1, VEGF and EGF in women exposed to prolonged psychosocial stress. Statistical analysis indicates that they independently associate with a significant risk for being classified as ill. Conclusions MCP-1, EGF, and VEGF are potential markers for screening and early intervention in women under prolonged psychosocial stress.

Abstract
Nocturnal home hemodialysis (NHD) is associated with an increase in hemoglobin level. We hypothesized that NHD enhances the removal of toxins of hematopoietic progenitor cells (HPCs), thereby improving HPC growth and function. Among 16 patients with ESRD, 2 mo of NHD nearly doubled Kt/V per session and significantly lowered both parathyroid hormone levels and serum phosphate concentration. In addition, treatment with NHD improved hemoglobin levels from 113 +/- 3 to 125 +/- 4 g/L (P = 0.03) without altering erythropoietin requirements or iron status. To assess whether NHD may enhance removal of HPC toxins, we collected paired plasma samples from the same patient during treatment with conventional HD and NHD. In vitro, growth of erythroid (BFU-E) and granulocytic (CFU-GM) colonies was superior when cultured with NHD plasma compared with conventional HD plasma. Differential gene expression profiles obtained from peripheral blood and HPC colonies revealed similar upregulation of genes responsible for HPC mobilization and growth and production of red blood cells. In conclusion, the enhanced clearance by NHD is associated with an improvement in HPC growth and a coordinated increase in expression of genes relevant to production of red blood cells.

Abstract
In the course of new blood vessel formation, two different processes--vasculogenesis and angiogenesis--have to be distinguished. The term vasculogenesis describes the de novo emergence of a vascular network by endothelial progenitors, whereas angiogenesis corresponds to the generation of vessels by sprouting from pre-existing capillaries. Until recently, it was thought that vasculogenesis is restricted to the prenatal period. During the last decade, one of the most fascinating innovations in the field of vascular biology was the discovery of endothelial progenitor cells and vasculogenesis in the adult. This review aims at introducing the concept of adult vasculogenesis and discusses the efforts to identify and characterize adult endothelial progenitors. The different sources of adult endothelial progenitors like haematopoietic stem cells, myeloid cells, multipotent progenitors of the bone marrow, side population cells and tissue-residing pluripotent stem cells are considered. Moreover, a survey of cellular and molecular control mechanisms of vasculogenesis is presented. Recent advances in research on endothelial progenitors exert a strong impact on many different disciplines and provide the knowledge for functional concepts in basic fields like anatomy, histology as well as embryology.

Abstract
Abstract
Interleukin-3 (IL-3) released by infiltrating inflammatory cells in different pathologic settings contributes to organ and tumor angiogenesis. Here we demonstrate that IL-3 expands a subset of CD45+ circulating angiogenic cells clonally derived from the hemopoietic progenitors. Moreover, CD45+ cells exposed to IL-3 acquire arterial specification and contribute to the formation of vessels in vivo. Depletion of signal transducer and activator of transcription 5 (STAT5) provides evidence that IL-3–mediated cell expansion and arterial morphogenesis rely on STAT5 activation. In addition, by means of Tie2-transgenic mice, we demonstrate that STAT5 also regulates IL-3–induced expansion and arterial specification of bonemarrow–derived CD45+ cells. Thus, our data provide the first evidence that, in inflammatory microenvironments containing IL-3, angiogenic cells derived from hemopoietic precursors can act as adult vasculogenic cells. Moreover, the characterization of the signaling pathway regulating these events provides the rationale for therapeutically targeting STAT5 in these pathologic settings.

Abstract
Mobilization of endothelial progenitor cells (EPCs) from the bone marrow and their subsequent participation in neovessel formation are implicated in tumor growth and neovascularization. As the neurotransmitter dopamine (DA) modulates adult endothelial cell function, we hypothesized that DA might have a regulatory role in mobilization of EPCs from the bone marrow niche. We show that there was a significant decrease in bone marrow DA content and an increase in EPC mobilization in tumor-bearing mice associated with tumor neovascularization. DA treatment of tumor-bearing mice inhibited EPC mobilization and tumor growth through its D2 receptors, as DA treatment failed to inhibit EPC mobilization in tumor-bearing mice treated with a specific DA D2 receptor antagonist and in tumor-bearing mice lacking the D2 receptor. In addition, we found that DA, through D2 receptors, exerted its inhibitory effect on EPC mobilization through suppression of VEGFA-induced ERK1/ERK2 phosphorylation and MMP-9 synthesis. These findings reveal a new link between DA and EPC mobilization and suggest a novel use for DA and D2 agents in the treatment of cancer and other diseases involving neovessel formation.

Abstract
The bone marrow constitutes an unique microenvironment for cancer cells in three specific aspects. First, the bone marrow actively recruits circulating tumor cells where they find a sanctuary rich in growth factors and cytokines that promote their proliferation and survival. When in the bone marrow, tumor cells profoundly affect the homeostasis of the bone and the balance between osteogenesis and osteolysis. As a consequence, growth and survival factors normally sequestered into the bone matrix are released, further fueling cancer progression. Second, tumor cells actively recruit bone marrow-derived precursor cells into their own microenvironment. When in the tumors, these bone marrow-derived cells contribute to an inflammatory reaction and to the formation of the tumor vasculature. Third, bone marrow-derived cells can home in distant organs, where they form niches that attract circulating tumor cells. Our understanding of the contribution of the bone marrow microenvironment to cancer progression has therefore dramatically improved over the last few years. The importance of this new knowledge cannot be underestimated considering that the vast majority of cancer treatments such as cytotoxic and myeloablative chemotherapy, bone marrow transplantation and radiation therapy inflict a trauma to the bone marrow microenvironment. How such trauma affects the influence that the bone marrow microenvironment exerts on cancer is still poorly understood. In this article, the reciprocal relationship between the bone marrow microenvironment and tumor cells is reviewed, and its potential impact on cancer therapy is discussed.

Abstract
Erythropoietin (Epo) expression is regulated via hypoxia-inducible factor (HIF)-1alpha-directed gene transcription. Activation of the erythropoietin receptor (EpoR) by Epo leads to elevated expression of the anti-apoptotic protein, bcl-2, which has recently been shown to promote angiogenesis in malignant tumors. Expression of HIF-1alpha, Epo, EpoR, and bcl-2 was studied by immunohistochemistry in a series of 20 olfactory neuroblastoma (ONB) samples. Data were correlated with microvessel density, proliferative activity, and apoptosis in the specimens and survival analysis was performed to investigate the prognostic value of the examined factors. Immunohistochemical analysis revealed robust expression of HIF-1alpha, Epo, EpoR, and bcl-2 in ONB. Ninety percent of the samples showed HIF-1alpha immunoreactivity and in 60% of the cases, bcl-2 immunoreactivity was observed. A significant positive correlation between the expression levels of HIF-1alpha and bcl-2 and the microvessel density was found. Survival analysis did not reveal any prognostic significance for the tested factors. Expression of HIF-1alpha, Epo, Epo-R, and bcl-2 may play a functional role in ONB pathogenesis. Our data suggest that bcl-2 may act as a stimulator of angiogenesis in ONB, and thus represents a novel target for anti-angiogenic treatment strategies in the therapy of ONB.

Abstract
BACKGROUND Enhanced mechanical forces, e.g. in arterial hypertension, stimulate the formation of reactive oxygen species (ROS) by the NAD(P)H oxidase. Since bone marrow derived endothelial progenitor cells (EPCs) contribute to vascular remodeling and repair, we investigated whether renovascular hypertension stimulates EPC mobilization in a NAD(P)H oxidase-dependent manner. METHODS Renovascular hypertension was induced by two-kidney one-clip (2K1C) in C57BL/6 (WT) and in mice lacking the p47phox subunit of the NAD(P)H oxidase (p47phox-/-). RESULTS In WT, 2K1C increased blood pressure levels by 32.4 +/- 4 mmHg, which was associated with a four-fold increase in circulating EPCs (Sca-1+;Flk-1+). In p47phox-/- mice, the increase in blood pressure was significantly reduced (15.1 +/- 1.8 mmHg, P < 0.05) and not associated with increased EPCs. Inhibitors of the renin-angiotensin system (RAS) and nonspecific vasodilators normalized blood pressure and inhibited EPC mobilization in WT mice after 2K1C. In addition, p47phox deficiency and pharmacological ROS blockage abrogated 2K1C-induced blood pressure elevation and EPC mobilization. Stromal cell derived factor (SDF)-1 and matrix metalloproteinase (MMP)-9 activity in the bone marrow, required for EPC mobilization, were modulated in WT mice after 2K1C. In contrast, no alterations in SDF-1 and MMP-9 were observed in p47phox-/- mice. Moreover, enhanced migration of Lin- bone marrow mononuclear cells was observed when stimulated with plasma from 2K1C WT mice but not when stimulated with plasma from 2K1C p47phox-/- mice. CONCLUSION Enhanced mechanical stretch in renovascular hypertension induces EPC mobilization in a p47phox-dependent manner, involving bone marrow SDF-1 and MMP-9 which may contribute to compensatory vascular adaptation in renovascular hypertension.

Abstract
Bone marrow-derived cells are recruited into tumor vasculature in response to angiogenic signals, and some of the cells within the newly forming tumor vessels are hematopoietic stem cells (HSCs) in origin. Previous studies suggest that bone marrow-derived pericytes are associated with newly formed vessels in tumors. In this study, we used an orthotopic rat glioma model (RT-2/RAG) to examine the contribution of long-term hematopoietic stem cell (LT-HSC)-derived pericytic cells to brain tumor angiogenesis. Mice (RAG-2/KO5.2) were lethally irradiated, and their hematopoietic cells were repopulated by transplantation of double fluorescence-activated cell-sorted LT-HSCs that express green fluorescent protein (GFP+). RT-2/RAG cells were then injected into the striatum of the chimeric mice 6 weeks post-transplantation. The animals were sacrificed 9 days after tumor implantation, and the incorporation and lineage-specific marker expression profile of the GFP+ cells within the growing tumor and tumor periphery were analyzed. LT-HSC-derived GFP+ cells were noted to incorporate onto the surface of tumor vessels within the perivascular space. LT-HSC-derived GFP+ cells express the pericyte progenitor marker, platelet-derived growth factor receptor-beta (PDGFR beta), as well as mature perictyte markers such as nerve/glial antigen 2 proteoglycan (NG2), alpha-smooth muscle actin (alpha SMA), and desmin. These LT-HSC-derived cells may represent a population of progenitor or committed pericytes within the neovascular tree and may play a role in shaping the angio-architecture in the vascular niche of brain tumors.

Abstract
Mesenchymal stem cells (MSC) exhibit tropism for sites of tissue damage as well as the tumor microenvironment. Many of the same inflammatory mediators that are secreted by wounds are found in the tumor microenvironment and are thought to be involved in attracting MSC to these sites. Cell migration is dependent on a multitude of signals ranging from growth factors to chemokines secreted by injured cells and/or respondent immune cells. MSC are likely to have chemotactic properties similar to other immune cells that respond to injury and sites of inflammation. Thus, the well-described model of leukocyte migration can serve as a reasonable example to facilitate the identification of factors involved in MSC migration. Understanding the factors involved in regulating MSC migration to tumors is essential to ultimately develop novel clinical strategies aimed at using MSC as vehicles to deliver antitumor proteins or suppress MSC migration to reduce tumor growth. For example, radiation enhances inflammatory signaling in the tumor microenvironment and may be used to potentiate site-specific MSC migration. Alternatively, restricting the migration of the MSC to the tumor microenvironment may prevent competent tumor-stroma formation, thereby hindering the growth of the tumor. In this review, we will discuss the role of inflammatory signaling in attracting MSC to tumors.

Abstract
Development of hypoxic regions is an indicator of poor prognosis in many tumors. Here, we demonstrate that HIF1alpha, the direct effector of hypoxia, partly through increases in SDF1alpha, induces recruitment of bone marrow-derived CD45+ myeloid cells containing Tie2+, VEGFR1+, CD11b+, and F4/80+ subpopulations, as well as endothelial and pericyte progenitor cells to promote neovascularization in glioblastoma. MMP-9 activity of bone marrow-derived CD45+ cells is essential and sufficient to initiate angiogenesis by increasing VEGF bioavailability. In the absence of HIF1alpha, SDF1alpha levels decrease, and fewer BM-derived cells are recruited to the tumors, decreasing MMP-9 and mobilization of VEGF. VEGF also directly regulates tumor cell invasiveness. When VEGF activity is impaired, tumor cells invade deep into the brain in the perivascular compartment.

Abstract
This article reviews the association between bone and artery disease, with particular relevance to progenitor cells. The review was based on insight gained by analysis of previous publications and on-going work by the authors. A large number of studies have demonstrated a correlation between bone pathology, particularly osteoporosis, and atherosclerosis. In this review we highlight the particular aspect of bone marrow progenitor cells in the bone-artery link. Progenitor cells, primarily those believed to give rise to endothelial cells, have been inversely correlated with atherosclerosis severity and risk factors. Therapeutic approaches aimed at manipulating progenitor cells in revascularization and vascular repair have demonstrated some promising results. Subtypes of progenitor cells have also been linked with vascular pathology, however, and further studies are required to assess relative beneficial and pathologic effects of bone marrow-derived progenitors. Further understanding of the link between bone and artery pathophysiology is likely to be of significant value in developing new therapies for vascular disease.

Abstract
A novel population of tissue-resident endothelial precursors (TEPs) was isolated from small blood vessels in dermal, adipose, and skeletal muscle of mouse based on their ability to be grown as spheres. Cellular and molecular analyses of these cells revealed that they were highly related regardless of the tissue of origin and distinct from embryonic neural stem cells. Notably, TEPs did not express hematopoietic markers, but they expressed numerous characteristics of angiogenic precursors and their differentiated progeny, such as CD34, Flk-1, Tie-1, CD31, and vascular endothelial cadherin (VE-cadherin). TEPs readily differentiated into endothelial cells in newly formed vascular networks following transplantation into regenerating skeletal muscle. Taken together, these experiments suggest that TEPs represent a novel class of endothelial precursors that are closely associated with small blood vessels in muscle, adipose, and dermal tissue. This finding is of particular interest since it could bring new insight in cancer angiogenesis and collateral blood vessels developed following ischemia. Disclosure of potential conflicts of interest is found at the end of this article.
