“…Under the certain induction, the cells can differentiate into mesodermderived osteoblasts, chondrocytes and adipocytes, and also liver cells, heart cells and nerve cells (1)(2)(3)13,20,23,28,31,33). As demonstrated by in vitro studies, MSCs secrete various cell factors, for example, factor derived from matrix, hepatocyte growth factor, insulin-like growth factor, fibroblast growth factor, ischemia-induced factor, vascular endothelial stem cell transplantation, it exerts the immunomodulatory function via the secretion of autocrine and paracrine cytokines to promote angiogenesis in local ischemic tissue, while MSCs can integrate the damaged vascular plexus and then directly differentiate into mature new blood vessels (8,9,16).…”
