Fig. 2From: Recombinant TSG-6 protein inhibits the growth of capsule fibroblasts in frozen shoulder via suppressing the TGF-β/Smad2 signal pathwayRecombinant TSG-6 protein inhibited the proliferation and promotes the apoptosis of fibroblasts. Notes: A MMT assay was used to detect the viability of fibroblasts in each group. B Colony formation assay was performed to determine the proliferation of fibroblasts in each group. C The apoptosis of fibroblasts in each group was detected by flow cytometry. D Western Blot was carried out to examine the levels of Bax and Bcl-2 of fibroblasts in each group. *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
