Protein and mRNA expressions of fibrous markers (α-SMA, COL-1) in fibroblasts from the IF and CF groups. a Western blot using specific antibodies for α-SMA and COL-1. b qRT-PCR results of α-SMA and COL-1 were shown. The asterisk indicates p < 0.05 compared to the CF group. IF fibroblasts derived from the immobilized knees, CF fibroblasts derived from the contralateral knees. GAPDH was used as the internal reference in the Western blot
