Poly-L-lysine Prevents Senescence and Augments Growth in Culturing Mesenchymal Stem Cells Ex Vivo

Figure 4

Differentiation potential of cells cultured on uncoated and poly-L-lysine- (PLL-) coated plates. (a) Osteogenesis was determined by Von Kossa staining and calcium quantification. (b) Adipogenesis was examined by oil red O staining. For quantitative analysis, absorbance was detected after destaining. (c) Chondrogenesis was analysed by safranin O staining and glycosaminoglycan quantification. The data represent the mean ± standard deviation of three independent experiments. .
