    Abstract:
    Mesenchymal stem cells (MSCs) and endothelial progenitor cells (EPCs) are attached to each other in the bone marrow (BM) cavity and in in vitro cultures, and this adhesion has important physiological significance. We demonstrated that cell proliferation could be promoted when MSCs were co-cultured with EPCs, which was beneficial to angiogenesis, tissue repair, and regeneration. The adhesion of MSCs and EPCs could promote the pluripotency of MSCs, particularly self-renewal and multi-differentiation to osteoblasts, chondrocytes, and adipocytes. This study focused on the mechanism of adhesion between EPCs and MSCs. The results showed that E-cadherin (E-cad) mediated the adhesion of MSCs and EPCs through the E-cad/beta-catenin signaling pathway. The E-cad of EPCs occupied a dominant position during this process, which activated and up-regulated the beta-catenin (β-catenin) of MSCs to improve cohesion and exert their biological function.
