Abstract
There are many gynecological diseases, among which breast cancer (BC), cervical cancer (CC), endometriosis (EMs), and polycystic ovary syndrome (PCOS) are common and difficult to cure. Stem cells (SCs) are a focus of regenerative medicine. They are commonly used to treat organ damage and difficult diseases because of their potential for self-renewal and multidirectional differentiation. SCs are also commonly used for difficult-to-treat gynecological diseases because of their strong directional differentiation ability with unlimited possibilities, their tendency to adhere to the diseased tissue site, and their use as carriers for drug delivery. SCs can produce exosomes in a paracrine manner. Exosomes can be produced in large quantities and have the advantage of easy storage. Their safety and efficacy are superior to those of SCs, which have considerable potential in gynecological treatment, such as inhibiting endometrial senescence, promoting vascular reconstruction, and improving anti-inflammatory and immune functions. In this paper, we review the mechanisms of the regenerative and anti-inflammatory capacity of SCs and exosomes in incurable gynecological diseases and the current progress in their application in genetic engineering to provide a foundation for further research.

Abstract
Cardiovascular disease is a primary cause of mortality worldwide, and patients often require bypass surgery that utilizes autologous vessels as conduits. However, the limited availability of suitable vessels and the risk of failure and complications have driven the need for alternative solutions. Tissue-engineered vascular grafts (TEVGs) offer a promising solution to these challenges. TEVGs are artificial vascular grafts made of biomaterials and/or vascular cells that can mimic the structure and function of natural blood vessels. The ideal TEVG should possess biocompatibility, biomechanical mechanical properties, and durability for long-term success in vivo. Achieving these characteristics requires a multi-disciplinary approach involving material science, engineering, biology, and clinical translation. Recent advancements in scaffold fabrication have led to the development of TEVGs with improved functional and biomechanical properties. Innovative techniques such as electrospinning, 3D bioprinting, and multi-part microfluidic channel systems have allowed the creation of intricate and customized tubular scaffolds. Nevertheless, multiple obstacles must be overcome to apply these innovations effectively in clinical practice, including the need for standardized preclinical models and cost-effective and scalable manufacturing methods. This review highlights the fundamental approaches required to successfully fabricate functional vascular grafts and the necessary translational methodologies to advance their use in clinical practice.

Abstract
Vascular transplantation is an effective strategy against cardiovascular diseases (CVD), and artificial vascular patches are of urgent need across the world. In this work, we designed a multifunctional decellularized scaffolds (DCS)-based vascular patch for porcine vascular repair. Ammonium phosphate zwitter-ion (APZI) and poly(vinyl alcohol) (PVA) hydrogel were coated on the surface of DCS to improve the mechanical properties and biocompatibility of an artificial vascular patch. Then a heparin (Hep)-loaded metal-organic framework (MOF) further decorated the artificial vascular patches to inhibit blood coagulation and promote vascular endothelialization. The obtained artificial vascular patch showed suitable mechanical properties, good biocompatibility, and blood compatibility. In addition, the proliferation and adhesion of endothelial progenitor cells (EPCs) on the surface of artificial vascular patch improved a lot when compared with unmodified PVA/DCS. According to the results of B-ultrasound and CT images, the artificial vascular patch could maintain the patency of the implant site after implanting into the pig carotid artery. The current results solidly support that a MOF-Hep/APZI-PVA/DCS vascular patch would be an excellent vascular replacement material.

Abstract
Vascular grafts are widely used for vascular surgeries, to bypass a diseased artery or function as a vascular access for hemodialysis. Bioengineered or tissue-engineered vascular grafts have long been envisioned to take the place of bioinert synthetic grafts and even vein grafts under certain clinical circumstances. However, host responses to a graft device induce adverse remodeling, to varied degrees depending on the graft property and host's developmental and health conditions. This in turn leads to invention or failure. Herein, we have mapped out the relationship between the design constraints and outcomes for vascular grafts, by analyzing impairment factors involved in the adverse graft remodeling. Strategies to tackle these impairment factors and counteract adverse healing are then summarized by outlining the research landscape of graft innovations in three dimensions-cell technology, scaffold technology and graft translation. Such a comprehensive view of cell and scaffold technological innovations in the translational context may benefit the future advancements in vascular grafts. From this perspective, we conclude the review with recommendations for future design endeavors.

Abstract
Aim: To evaluate the suitability of using aorta elastin scaffold, in combination with human adipose-derived mesenchymal stem cells (hAd-MSCs), as an approach for cardiovascular tissue engineering. Materials & Methods: Human adipose-derived MSCs were seeded on elastin samples of decellularized bovine aorta. The samples were cultured in vitro to investigate the inductive effects of this scaffold on the cells. The results were evaluated using histological, and immunohistochemical methods, as well as MTT assay, DNA content, reverse transcription-PCR and scanning electron microscopy. Results: Histological staining and DNA content confirmed the efficacy of decellularization procedure (82% DNA removal). MTT assay showed the construct's ability to support cell viability and proliferation. Cell differentiation was confirmed by reverse transcription-PCR and positive immunohistochemistry for alfa smooth muscle actin and von Willebrand. Conclusion: The prepared aortic elastin samples act as a potential scaffold, in combination with MSCs, for applications in cardiovascular tissue engineering. Further experiments in animal models are required to confirm this.

Abstract
INTRODUCTION Cardiovascular disease (CVD) is the leading cause of death in western countries. Although surgical outcomes for CVD are dramatically improving with the development of surgical techniques, medications, and perioperative management strategies, adverse postoperative events related to the use of artificial prosthetic materials are still problematic. Moreover, in pediatric patients, using these artificial materials make future re-intervention inevitable due to their lack of growth potential. AREAS COVERED This review focuses on the most current tissue-engineering (TE) technologies to treat cardiovascular diseases and discusses their limitations through reports ranging from animal studies to clinical trials. EXPERT OPINION Tissue-engineered structures, derived from a patient's own autologous cells/tissues and biodegradable polymer scaffolds, can provide mechanical function similar to non-diseased tissue. However, unlike prosthetic materials, tissue-engineered structures are hypothetically more biocompatible and provide growth potential, saving patients from additional or repetitive interventions. While there are many methods being investigated to develop TE technologies in the hopes of finding better options to tackle CVD, most of these approaches are not ready for clinical use or trials. However, tissue engineering has great promise to potentially provide better treatment options to vastly improve cardiovascular surgical outcomes.

Abstract
Tissue-engineered vascular grafts (TEVGs) are promising alternatives to small-diameter prosthetic grafts. Previous methods of seeding tubular scaffolds with autologous vascular cells have been successful; however, these methods require significant preparation time. Endothelial cell (EC) growth on the luminal surface of vascular scaffolds may be critical for the integration of a TEVG to the host environment. An alternative approach for TEVGs includes the in situ endothelialization of acellular scaffolds by capturing circulating endothelial progenitor cells (EPCs) and ECs from the bloodstream through the biofunctionalization of the vascular scaffolds. In this study, fibrous scaffolds were electrospun with a 1:1 poly(ε-caprolactone) (PCL)/collagen blend solution. The electrospun fibrous scaffolds were surface-modified by immobilizing EC-specific antibodies: CD31, vascular endothelial cadherin (VE-CAD), vascular endothelial growth factor receptor 2 (VEGFR2), and von Willebrand factor (vWF). Antibodies most efficacious at capturing ECs were then paired to examine their potential synergistic cell-capturing capabilities. The study demonstrated that vascular scaffolds bioconjugated with dual antibodies demonstrated synergistic capture efficacy compared to bioconjugation with a single antibody. The capture of circulating EPCs and ECs can be optimized with bioconjugation of one or more antibodies on the luminal surface of TEVGs.

Abstract
Application of stem cells in tissue engineering has proved to be effective in many cases due to great proliferation and differentiation potentials as well as possible paracrine effects of these cells. Human mesenchymal stem cells (MSCs) are recognized as a valuable source for vascular tissue engineering, which requires endothelial and perivascular cells. The goal of this review is to survey the potential of MSCs for engineering functional blood vessels in comparison with other cell types including bone marrow mononuclear cells, endothelial precursor cells, differentiated adult autologous smooth muscle cells, autologous endothelial cells, embryonic stem cells, and induced pluripotent stem cells. In conclusion, MSCs represent a preference in making autologous tissue-engineered vascular grafts (TEVGs) as well as off-the-shelf TEVGs for emergency vascular surgery cases.

Abstract
Design strategies for small diameter vascular grafts are converging toward native-inspired tissue engineered grafts. A new automated technology is presented that combines a dip-spinning methodology for depositioning concentric cell-laden hydrogel layers, with an adapted solution blow spinning (SBS) device for intercalated placement of aligned reinforcement nanofibres. This additive manufacture approach allows the assembly of bio-inspired structural configurations of concentric cell patterns with fibres at specific angles and wavy arrangements. The middle and outer layers were tuned to structurally mimic the media and adventitia layers of native arteries, enabling the fabrication of small bore grafts that exhibit the J-shape mechanical response and compliance of human coronary arteries. This scalable automated system can fabricate cellularized multilayer grafts within 30 min. Grafts were evaluated by hemocompatibility studies and a preliminary in vivo carotid rabbit model. The dip-spinning-SBS technology generates constructs with native mechanical properties and cell-derived biological activities, critical for clinical bypass applications.

Plasticity of Adipose Tissue-Derived Stem Cells and Regulation of Angiogenesis. Front Physiol 2018; 9:1656.

Abstract
Adipose tissue is recognized as an important organ with metabolic, regulatory, and plastic roles. Adipose tissue-derived stem cells (ASCs) with self-renewal properties localize in the stromal vascular fraction (SVF) being present in a vascular niche, thereby, contributing to local regulation of angiogenesis and vessel remodeling. In the past decades, ASCs have attracted much attention from biologists and bioengineers, particularly, because of their multilineage differentiation potential, strong proliferation, and migration abilities in vitro and high resistance to oxidative stress and senescence. Current data suggest that the SVF serves as an important source of endothelial progenitors, endothelial cells, and pericytes, thereby, contributing to vessel remodeling and growth. In addition, ASCs demonstrate intriguing metabolic and interlineage plasticity, which makes them good candidates for creating regenerative therapeutic protocols, in vitro tissue models and microphysiological systems, and tissue-on-chip devices for diagnostic and regeneration-supporting purposes. This review covers recent achievements in understanding the metabolic activity within the SVF niches (lactate and NAD+ metabolism), which is critical for maintaining the pool of ASCs, and discloses their pro-angiogenic potential, particularly, in the complex therapy of cardiovascular and cerebrovascular diseases.

Abstract
Recent advances in the field of induced pluripotent stem cells (iPSCs) research have opened a new avenue for stem cell-based generation of vascular cells. Based on their growth and differentiation potential, human iPSCs constitute a well-characterized, generally unlimited cell source for the mass generation of lineage- and patient-specific vascular cells without any ethical concerns. Human iPSCs-derived vascular cells are perfectly suited for vascular disease modeling studies because patient-derived iPSCs possess the disease-causing mutation, which might be decisive for full expression of the disease phenotype. The application of vascular cells for autologous cell replacement therapy or vascular engineering derived from immune-compatible iPSCs possesses huge clinical potential, but the large-scale production of vascular-specific lineages for regenerative cell therapies depends on well-defined, highly reproducible culture and differentiation conditions. This review will focus on the different strategies to derive vascular cells from human iPSCs and their applications in regenerative therapy, disease modeling and drug discovery approaches.

Shear stress: An essential driver of endothelial progenitor cells. J Mol Cell Cardiol 2018; 118:46-69.

Abstract
The blood flow through vessels produces a tangential, or shear, stress sensed by their innermost layer (i.e., endothelium) and representing a major hemodynamic force. In humans, endothelial repair and blood vessel formation are mainly performed by circulating endothelial progenitor cells (EPCs) characterized by a considerable expression of vascular endothelial growth factor receptor 2 (VEGFR2), CD34, and CD133, pronounced tube formation activity in vitro, and strong reendothelialization or neovascularization capacity in vivo. EPCs have been proposed as a promising agent to induce reendothelialization of injured arteries, neovascularization of ischemic tissues, and endothelialization or vascularization of bioartificial constructs. A number of preconditioning approaches have been suggested to improve the regenerative potential of EPCs, including the use of biophysical stimuli such as shear stress. However, in spite of well-defined influence of shear stress on mature endothelial cells (ECs), articles summarizing how it affects EPCs are lacking. Here we discuss the impact of shear stress on homing, paracrine effects, and differentiation of EPCs. Unidirectional laminar shear stress significantly promotes homing of circulating EPCs to endothelial injury sites, induces anti-thrombotic and anti-atherosclerotic phenotype of EPCs, increases their capability to form capillary-like tubes in vitro, and enhances differentiation of EPCs into mature ECs in a dose-dependent manner. These effects are mediated by VEGFR2, Tie2, Notch, and β1/3 integrin signaling and can be abrogated by means of complementary siRNA/shRNA or selective pharmacological inhibitors of the respective proteins. Although the testing of sheared EPCs for vascular tissue engineering or regenerative medicine applications is still an unaccomplished task, favorable effects of unidirectional laminar shear stress on EPCs suggest its usefulness for their preconditioning.

Abstract
Instability and poor targeting causes the long-term patency of RNA-modified tissue engineering blood vessels (TEBVs) remaining unsatisfactory. RNA can be enriched in exosome and then delivered into targeted cells while whether exosome-modified TEBVs achieve RNA targeted delivery is unclear. Here, to promote the expression of klotho protein on the mesenchymal stem cell (MSC)-derived exosomes, klotho plasmids are first transfected into MSCs, and adenosine kinase (ADK) siRNA is then loaded into exosome (klotho/ADK siRNA-exosome) using electrotransfection. Flow chamber results show that klotho/ADK siRNA-exosome can effectively capture circulating endothelial progenitor cells (EPCs). Besides, the captured EPCs can endocytose this exosome, and then decompose it into klotho protein and ADK siRNA. Moreover, ADK siRNA promotes the paracrine of proangiogenic factors and adenosine from EPCs, which further facilitate proliferation and migration of endothelial cells. Based on polyethyleneimine-capped gold nanoparticles, exosome-modified TEBVs are constructed through layer-by-layer assembly. Animal experimental results show that klotho/ADK siRNA-exosome-modified TEBVs can maintain the patency up to one month, and good endothelialization is observed. In short, one exosome-modified TEBV is constructed, capture molecules on the surface of exosome capture the circulating EPCs, and the loaded RNA achieves its purpose of accurate treatment depending on the needs of patients.

Abstract
INTRODUCTION Conventional synthetic vascular grafts are limited by the inability to remodel, as well as issues of patency at smaller diameters. Tissue-engineered vascular grafts (TEVGs), constructed from biologically active cells and biodegradable scaffolds have the potential to overcome these limitations, and provide growth capacity and self-repair. Areas covered: This article outlines the TEVG design, biodegradable scaffolds, TEVG fabrication methods, cell seeding, drug delivery, strategies to reduce wait times, clinical trials, as well as a 5-year view with expert commentary. Expert commentary: TEVG technology has progressed significantly with advances in scaffold material and design, graft design, cell seeding and drug delivery. Strategies have been put in place to reduce wait times and improve 'off-the-shelf' capability of TEVGs. More recently, clinical trials have been conducted to investigate the clinical applications of TEVGs.

Abstract
Vascular smooth muscle cells (VSMCs) derived from cardiovascular progenitor cell (CVPC) lineage populate the tunica media of the aortic root. Understanding differentiation of VSMCs from CVPC will further our understanding of the molecular mechanisms contributing to aortic root aneurysms, and thus, facilitate the development of novel therapeutic agents to prevent this devastating complication. It is established that the yes-associated protein (YAP) and Hippo pathway is important for VSMC proliferation and phenotype switch. To determine the role of YAP in differentiation of VSMCs from CVPCs, we utilized the in vitro monolayer lineage specific differentiation method by differentiating human embryonic stem cells into CVPCs, and then, into VSMCs. We found that expression of YAP decreased during differentiation of VSMC from CVPCs. Overexpression of YAP attenuated expression of VSMC contractile markers and impaired VSMC function. Knockdown of YAP increased expression of contractile proteins during CVPC-VSMCs differentiation. Importantly, expression of YAP decreased transcription of myocardin during this process. Overexpression of YAP in PAC1 SMC cell line inhibited luciferase activity of myocardin proximal promoter in a dose dependent and NKX2.5 dependent manners. YAP protein interacted with NKX2.5 protein and inhibited binding of NKX2.5 to the 5'-proximal promoter region of myocardin in CVPC-derived VSMCs. In conclusion, YAP negatively regulates differentiation of VSMCs from CVPCs by decreasing transcription of myocardin in a NKX2.5-dependent manner. Stem Cells 2017;35:351-361.
