The effect of non-growth factors on chondrogenic differentiation of mesenchymal stem cells.

Chondrogenic differentiation of mesenchymal stem cells (MSCs) in vitro usually requires the presence of growth factors in the culture condition. But many cost-effect methods can successfully fulfill this without addition of these cytokines. This article focuses upon the effect of non-growth factors on the chondrogenic differentiation of MSCs and the concise introduction of the potential mechanism of these methods.
