Insufficient vascularization is a major obstacle for clinical application of tissue engineered transplants including bone. The ambition is to provide an environment rich in vascular networks to achieve efficient osseointegration and accelerate functional restoration after implantation. Of particular interest is the microvasculature that is crucial for oxygen and nutrient delivery....
Background:
Mesenchymal stem cell (MSCs) -based therapy has a promising potential in bone tissue regeneration. Although, growing evidence has suggested that paracrine mechanisms may be involved in the underlying mechanism of MSC transplantation, and extracellular vesicles (EVs) are an important component of this paracrine role. However, information on the influence of different...
Introduction
Endothelial cells (ECs) have potential in bone tissue engineering due to their important role on vascularization. For repairing bone defects, co-culturing of ECs and bone marrow stem cells (BMSCs) is suggested to induce both the capillary network formation and bone regeneration. The communication between the two cell types has been experimented on settings based on cell number...
INTRODUCTION: Mesenchymal stromal cells (MSC) combined with biphasic calcium phosphate biomaterial (BCP) is a promising clinical strategy to repair and regenerate lost bones [1]. Further, MSC derived extracellular vesicles (MSC:EV) are established factors of paracrine inter-cellular communication with various cell types, including immune cells, which impacts their regenerative potential [2] ....
Introduction: Adipose tissue-derived stem cells (ATSCs) have been used as an alternative to bone marrow mesenchymal stem cells (BMSCs) for bone tissue engineering. However, several studies have reported that the efficacy of ATSCs in bone regeneration in comparison with BMSCs remains inferior 1,2. The aim of this study was to investigate the mechanism underlying differences in ATSCs versus...
Introduction
Mesenchymal stem cells (MSC) regulate their behavior by sensing mechano-environmental factors.
Accumulated evidence indicates that appropriate mechanical force including fluid shear stress enhances the osteogenic property of MSC on 3D polymeric scaffolds even without the presence of osteogenic cocktail (i.e., dexamethasone and beta-glycerophosphate). However, despite a common...
Introduction: The management of long bone critical-size defects leading to nonunion remains a major clinical orthopaedic challenge. Mesenchymal stem cell (MSC)-based therapies are promising strategies for bone healing of critical-size defects. Preliminary studies suggested that implantation of Interleukin-4 (IL-4) overexpressing MSCs within a gelatin microribbon (ยตRB) scaffold during the early...
