Figure 8: Immunohistochemical staining of samples collected 7 days after autologous MDCs injection. (a and b) PKH26 positive cells (red) can be recognized between and within muscle fibers (arrow), desmin stained with Alexa 488 (green); (c and d) PKH26 positive cells (red) can be recognized in the central position of muscle fiber (arrowhead) indicating the ability to contribute muscle regeneration. Few macrophages (CD68 stained with Alexa 488 (green)) are still present in the site of transplantation. Scale bars: 50 μm.
