Protein expression analysis. Immunostaining for BMP-2, myostatin, and CD44 was evaluated by counting the number of positive fibers/cells on 25-high power field (HPF), whereas western blot for BMP-2 was evaluated by lines densitometry. (a) Notably, we found that OA muscle biopsies showed a significantly higher number of BMP-2-positive fibers (293.0 ± 35.4) as compared with muscle of OP patients (162.1 ± 33.7) (p < 0.0001). (b) Western blot lines show a higher expression of BMP-2 in OA patients compared to OP group. (c) The number of myostatin positive fibers in OP patients was significantly higher compared to OA group (p < 0.0200). (d) CD44 expression shows a significantly different rate of CD44 positive cells in OA group as compared with OP (p < 0.0020).
