Abstract
Controlling stem cell fate is the cornerstone of regenerative medicine. Cadherins have an important role in cell fate commitment and the function of cadherin-11 in the regulation of differentiation in human mesenchymal stem cells (hMSCs) has recently come to light. To better understand how cadherin-11 regulates hMSC behavior, we explored its interaction with receptor tyrosine kinases (RTK), an important family of proteins involved in a myriad of cellular functions. In this study, we provide evidence that cadherin-11, a cell adhesion protein expressed in hMSCs, regulates the activity of several RTKs, including PDGFRβ and PDGFRα. By knocking down cadherin-11 we found that the changes in the RTK activity caused hyperactivation of the MAPK pathways, which were sustained through the phosphorylation and nuclear translocation of ERK1/2 and subsequently caused a decrease in cell proliferation. Together these results provide compelling evidence for the important role of the interaction of cadherin-11 and RTKs in the behavior of hMSCs.
