Fig. 6. Analysis of BM-cell trafficking to skeletal muscle MP and SP cells in the absence (A-C) or in the presence (D-F) of cardiotoxin injury (Mouse B in Table 2). FACS profiles and percentages of SP and MP cells in control (A) or cardiotoxin-injected muscles (D). Percentage of CD45.2+ donor-derived cells in muscle MP cells in the absence (B) or presence (E) of cardiotoxin injury. A near 5-fold increase of donor-derived cells is observed upon cardiotoxin injury in the MP population. Percentage of CD45.2+ donor-derived cells in muscle SP cell population in control (C) or in cardiotoxin-injured (F) muscles.
