ABSTRACT
AIM:
To investigate the differentiation of human bone marrow mesenchymal stem cells (MSC) into chondrocytes in vitro and determine factors involving in the differentiation process.METHODS:
MSC were separated from iliac bone marrow with lymphocyte separating medium using density centrifugation. Cells were cultured and expanded in medium until reaching required number. MSC was induced to differentiate into chondrocytes by adopting high cell density, supplying growth factor and using micromass culture. Cells were observed by HE staining. Matrix of cartilage was detected by alcian blue and toludine blue and cartilage specific collagen II was detected by immunohistochemistry.RESULTS:
The structure of the micromass assumed that of cellular cartilage, alcian blue staining were uniformly positive and toludine blue detected diffuse metachromasia substance, cells uniformly expressed collagen Ⅱ.CONCLUSION:
High cell density, growth factor and appropriate culture conditions are critical to induce differentiation of MSC into chondrocytes. [
