Satellite cells study. a Graph display the number of Pax7 and myogenin satellite cells in OA, OP and CTRL patients. b Image shows numerous Pax7 positive cells in a muscle biopsy of OA patient (arrows) (40×). c Muscle tissue of OP patient characterize by no/rare Pax7 positive satellite cells (40×). d Image displays numerous Pax7 positive cells in a muscle biopsy of a CTRL patient (arrows) (40×). e Arrows mark myogenin positive cells in a muscle biopsy of OA patient (40×). f Muscle tissue of OP patient characterize by no/rare myogenin positive satellite cells (40×). g Image displays numerous myogenin positive satellite cells in a muscle biopsy of a CTRL patient (arrows) (40×)
