Effects on Proliferation and Differentiation of Human Umbilical Cord-Derived Mesenchymal Stem Cells Engineered to Express Neurotrophic Factors

Figure 6

The effect of the overexpression of NTFs on the chondrogenic differentiation of MSCs. Transduced MSCs were cultured in chondrogenic induction medium for 21 days. (a) Cells were stained with anti-human aggrecan antibody and pictured in representative areas. Scale bar = 100 μm. (b) Relative aggrecan levels ().
