Abstract
High-cell density culture is based on the chondrogenic differentiation of human mesenchymal stem cells (hMSCs), and because the high density of
cell and reduced oxygen tension are effective in chondrogenic differentiation. In the present paper, there will be a review about the methods of
chondrogenic differentiation of hMSCs that utilized in in vitro and in vivo chondrogenic differentiation of stem cells for treatment of osteoarthritis.
There are three High-cell density culture systems; micromass, pellet culture, and alginate culture have been used to induce chondrogenic
differentiation of hMSCs. Transplanted naive MSCs can cause problems such as heterogeneous populations. To overcome this problem, new
strategies for inducing differentiation of MSCs are needed. One possibility is a cell culture system. Collagen II and aggrecan are critical protein in
chondrogenic differentiation. In all different methods, real time RT-PCR analysis demonstrates that collagen II and aggrecan mRNA are up
regulated while collagen X and collagen I mRNA are down regulated. So these three high-density cell culture systems have been approved for
chondrogenic differentiation. On the other hand, In micromass method, the induced-cartilage tissues are larger, more homogenous and rich in
cartilage specific collagen II, but collagen I, collagen X and hypertrophic chondrocyte features are markedly decreased compared to other culture
system. Thus, the micromass culture system is the best tool for in vitro chondrogenic differentiation studies.
