Figure Lengend Snippet: Fig. 4 OSM promotes early and mid-stage osteogenic differentiation of tendon stem cells through the JAK2/STAT3 signalling pathway. (A, B,E)After 7 days of OSM-induced osteogenic differentiation in the presence of AZD1480 and stattic, alkaline phosphatase staining was performed. Scale bar represents 200 μm. Expression of p-JAK2 and p-STAT3 proteins as well as osteogenic marker genes was analysed by western blotting and qPCR(n = 3). One-way ANOVA. (C, D,F) After 14 days of OSM-induced osteogenic differentiation in the presence of AZD1480 and stattic, alizarin red staining was performed. Scale bar represents 200 μm. Expression of p-JAK2 and p-STAT3 proteins and osteogenic marker genes were analysed by western blotting and qPCR, respectively (n = 3). One-way ANOVA. Data are presented as means ± standard deviation. *p < 0.05; **p < 0.01; ***p < 0.001
Article Snippet: To further analyse the effect of JAK2/STAT3 signalling on osteogenic differentiation of TDSCs, JAK2 inhibitor AZD1480 (10 μM, Santa Cruz Biotechnology, Dallas, TX), STAT3 inhibitor stattic (5 μM, Santa Cruz Biotechnology), or DMSO was added to the osteogenic differentiation medium with 25 ng/mL recombinant OSM to differentiate TDSCs for 7 and 14 days.
