In vitro differentiation of human umbilical cord-derived mesenchymal stem cells into CD34+ cells via CD34 antibody

چکیده
CD34 cells differentiated from mesenchymal stem cells (MSCs) have a strong biological function in cardiovascular regeneration. However, the molecular mechanisms of and the methods to improve the CD34 cell differentiation from MSCs, especially from human MSCs (hUC-MSCs) are still unclear. In the current study, the effect of CD34 antibody on the CD34 cell differentiation from human umbilical cord (UC)derived MSCs (hUC-MSCs) is determined. The results have demonstrated that the expression of cd34 protein is significantly increased in hUC-MSCs treated with CD34 antibody. In addition, the cell proliferation is increased in hUC-MSCs after treatment with CD34 antibody. Moreover, the expression of PI3K, AKT, p-AKT proteins, which are signaling molecules related to stem cell differentiation, is increased by CD34 antibody. The results suggest that CD34 antibody could promote the differentiation of hUC-MSCs into CD34 cells and PI3K/AKT may be involved in this important process.

3D study of capillary network derived from human cord blood mesenchymal stem cells and differentiated into endothelial cell with VEGFR2 protein expression
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...

Background: Mesenchymal stem cells (MSC) are a very promising transplantable stem cell source for a variety of cell replacement therapies. As the main source of MSC is bone marrow (BM), most of studies have been done on BM-derived MSC (BM-MSC). Umbilical cord (UC)-derived MSC (UC-MSC) which are recently introduced, is one of the good alternative source for these cells. The objective of this stu...
