Fig. 4

Chondrocyte differentiation of NSC on three different 2D substrates . NSCs are subject to cell differentiation on TCP, S-CHDM, and N-CHDM, respectively: a Representative images of F-actin (red) and COL II (green), as assessed via immunofluorescence, along with DAPI (blue) staining at 1 and 7 days. The scale bar is 100 μm. b Gene expression of Col2, Aggrecan, and Sox9, as examined via q-PCR on day 7. The expression levels are normalized to that of control (TCP) (n = 3, each group). Statistically significant difference as marked *p < 0.05 or **p < 0.01
