Cell proliferation and differentiation. (a) Representative images of DAPI staining for 2D (control group) and 3D (hydrogel group) cultured NPMSC at 1, 4, and 8 days after cultivation. (b) Representative images of Edu staining for 2D (control group) and 3D (hydrogel group) cultured NPMSC at 8 days after cultivation. (c) Investigation of growth rate and Edu-positive rate of NPMSC culture for 8 days in the control group and hydrogel group. (d) Relative protein levels of collagen type II and aggrecan in the control group and hydrogel group. Data represent ; the error bars represent the standard deviation of measurements for 3 separate samples (); compared with the hydrogel group. White scale .
