[PMID: 37953757 PMCID: PMC10632537 DOI: 10.1016/j.mtbio.2023.100846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 10/21/2023] [Accepted: 10/26/2023] [Indexed: 11/14/2023] Open
Abstract
3D bioprinting technology is widely used to fabricate various tissue structures. However, the absence of vessels hampers the ability of bioprinted tissues to receive oxygen and nutrients as well as to remove wastes, leading to a significant reduction in their survival rate. Despite the advancements in bioinks and bioprinting technologies, bioprinted vascular structures continue to be unsuitable for transplantation compared to natural blood vessels. In addition, a complete assessment index system for evaluating the structure and function of bioprinted vessels in vitro has not yet been established. Therefore, in this review, we firstly highlight the significance of selecting suitable bioinks and bioprinting techniques as they two synergize with each other. Subsequently, focusing on both vascular-associated cells and vascular tissues, we provide a relatively thorough assessment of the functions of bioprinted vascular tissue based on the physiological functions that natural blood vessels possess. We end with a review of the applications of vascular models, such as vessel-on-a-chip, in simulating pathological processes and conducting drug screening at the organ level. We believe that the development of fully functional blood vessels will soon make great contributions to tissue engineering and regenerative medicine.

Abstract
Homogeneous vascularization of implanted tissue constructs can extend to 5 weeks, during which cell death can occur due to inadequate availability of oxygen. Researchers are engineering biomaterials that generate and release oxygen in a regulated manner, in an effort to overcome this hurdle. A main limitation of the existing oxygen-generating biomaterials is the uncontrolled release of oxygen, which is ultimately detrimental to the cells. This study demonstrates the incorporation of calcium peroxide (CaO2) within a hydrophobic polymer, polycaprolactone (PCL), to yield composite scaffolds with controlled oxygen release kinetics sustained over 5 weeks. Oxygen-generating microparticles coencapsulated with cardiomyocytes in a gelatin-based hydrogel matrix can serve as model systems for cardiac tissue engineering. Specifically, the results reveal that the oxygen-generating microspheres significantly improve the scaffold mechanical strength ranging from 5 kPa to 35 kPa, have an average scaffold pore size of 50-100 μm, swelling ratios of 33.3-29.8%, and degradation with 10-49% remaining mass at the end of a 48 h accelerated enzymatic degradation. The oxygen-generating scaffolds demonstrate improvement in cell viability, proliferation, and metabolic activity compared to the negative control group when cultured under hypoxia. Additionally, the optimized oxygen-generating constructs display no cytotoxicity or apoptosis. These oxygen-generating scaffolds can possibly assist the in vivo translation of cardiac tissue constructs.

Abstract
As the largest organ of the human body, the skin has a complex multi-layered structure. The composition of the skin includes cells, extracellular matrix (ECM), vascular networks, and other appendages. Because of the shortage of donor sites, skin substitutes are of great significance in the field of skin tissue repair. Moreover, skin models for disease research, drug screening, and cosmetic testing fall far short of the demand. Skin tissue engineering has made remarkable progress in developing skin models over the years. However, there are still several problems to be resolved. One of the crucial aspects is the lack of vascular systems for nutrient transport and waste disposal. Here, we will focus on the discussion and analysis of advanced manufacturing strategies for prevascularized skin, such as a scaffold-based method, cell coating technology, cell sheet engineering, skin-on-a-chip, and three-dimensional (3D) bioprinting. These key challenges, which restrict the prevascularized skin and provide perspectives on future directions will also be highlighted.

[PMID: 35851415 PMCID: PMC9290299 DOI: 10.1186/s13287-022-03009-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 01/17/2022] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND Angiogenesis is required in many physiological conditions, including bone regeneration, wound healing, and tissue regeneration. Mesenchymal stem cells-derived extracellular matrix (MSCs-ECM) could guide intricate cellular and tissue processes such as homeostasis, healing and regeneration. METHODS The purpose of this study is to explore the effect and mechanism of ECM derived from decellularized Wharton's Jelly-derived mesenchymal stem cells (WJ-MSCs) on endothelial cell viability and angiogenesis. The human umbilical vein endothelial cells (HUVECs) were pretreated with WJ-MSCs ECM for 2d/7d/14d, respectively. After pretreatment, the angiogenesis ability of HUVECs was detected. RESULTS In this study, we found for the first time that WJ-MSCs ECM could improve the angiogenesis ability of HUVECs with a time-dependent manner in vitro. Mechanically, WJ-MSCs ECM activated the focal adhesion kinase (FAK)/P38 signaling pathway via integrin αVβ3, which further promoted the expression of the cellular (c)-Myc. Further, c-Myc increased histone acetylation levels of the vascular endothelial growth factor (VEGF) promoter by recruiting P300, which ultimately promoting VEGF expression. CONCLUSIONS ECM derived from Wharton's Jelly-derived mesenchymal stem cells promotes angiogenesis via integrin αVβ3/c-Myc/P300/VEGF. This study is expected to provide a new approach to promote angiogenesis in bone and tissue regeneration.
