Fig. 2From: In vitro study of cartilage tissue engineering using human adipose-derived stem cells induced by platelet-rich plasma and cultured on silk fibroin scaffoldProliferation of ADSCs cultured on silk fibroin scaffold with 500 μm pore size (ADSC-SS); Y axis is the proliferation rate of ADSC-SS, X axis indicates the observation day. The proliferation rate of ADSC-SS on various media is gradually increased. On day 21, the proliferation rate of ADSC-SS PRP group is significantly higher than negative and positive controls, respectively (*p < 0.05 indicates statistical significance)Back to article page
