ABSTRACT: 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.
