Research Abstract

I studied about the role of Dec2 in regulating chondrogenic differentiation of mesenchymal stem cells (MSCs). Overexpression of Dec2 decreased the expressions of proteoglycan and chondrocyte-related maker genes in chondrogenic-induced MSCs, suggesting that Dec2 negatively regulates chondrogenic differentiation. Dec2 also suppressed proliferation of MSCs in high-density pellet culture by regulating the expression of cell cycle-related genes such as cyclin D, p21 and p16.
