Fig. 6From: In vitro study of cartilage tissue engineering using human adipose-derived stem cells induced by platelet-rich plasma and cultured on silk fibroin scaffoldPercentage of type 2 collagen intensity in ADSC-SS PRP and control groups on days 7, 14, and 21. ADSC-SS PRP and positive control expressed significantly higher type 2 collagen percentage on day 14 and 21 compared to negative control group (*p < 0.05 indicates statistical significance)Back to article page
