tem cell biology has made cell-based therapies promising. While the use of human embryonic stem cells is ethically controversial, adult stem cells attracts more and more attention from clinicians and scientists. Adult mesenchymal stem cells (MSC) are derived from various tissues, including bone marrow, subcutaneous adipose tissue, cruciate ligament, muscle, and synovium,1 which are potential do...

Osteoblasts, osteoclasts, chondrocytes, and macrophages that participate in the bone repair process are derived from hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). However, the roles of these stem cells during the repair of injured bone tissue are still unclear. In the present study, we examined the effects of bone defect on HSCs and MSCs in bone marrow and spleen in 75 mice...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

Introduction: Previous investigations have indicated that the presence of BIO (6-Bromoindirubin-3-Oxime) in medium of some cell culture enhances the cell proliferation and viability. The aim of the present study was to investigate the BIO effects on in vitro expansion of rat marrow-derived mesenchymal stem cells (MSCs) culture. Methods: In the present experimental study, bone marrow cells from ...

background: mesenchymal stem cells (mscs) are important candidates for msc-based cellular therapy. current paradigm states that mscs support local progenitor cells in damaged tissue through paracrine signaling. therefore, study of paracrine effects and secretome of mscs could lead to the appreciation of mechanisms and molecules associated with the therapeutic effects of these cells. this study ...

objective(s) it is believed that the mesenchymal stem cell (msc) differentiation and proliferation are the results of activation of wnt signaling pathway. on the other hand, lithium chloride is reported to be able to activate this pathway. the objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived msc. materials and ...

OBJECTIVE For approximately 5% of autologous transplant recipients and a higher proportion of allogeneic transplant recipients, low level and delayed platelet engraftment is an ongoing problem. Mesenchymal stem cells (MSC), which can be derived from bone marrow as well as other organs, are capable of differentiation into multiple cell types and also support hematopoiesis in vitro. Because cotra...

Bones constructed by tissue engineering are being considered as valuable materials to be used for regeneration of large defects in natural bone. In an attempt to prepare a new bone construct, in this study, proliferation and bone differentiation of marrow-derived mesenchymal stem cells (MSCs) on our recently developed composite scaffolds of nano-, micro-hydroxyapatite/ poly(l-lactic acid) were ...
