The characterization of MIPCs, SC-derived myoblasts and BMSCs. a The proportion of CD146, nestin, CXCR4, PAX7, and FAP-positive cells in non-sorted MIPCs cultured for 5 days, CD146+ MIPCs isolated and sorted directly from the muscle (day 0) or cultured for 5 days (CD146+ MIPCs), (n = 3–4); the proportion of CD146, nestin, CXCR4, PAX7, and FAP-positive cells in SC-derived myoblasts cultured for 3 days (n = 3); the percentage of CD146, nestin, CXCR4, PAX7, and FAP-positive cells in CD146+ BMSCs and whole population of BMSCs cultured for 7–10 days, (n = 3–15); b localization of selected markers: CD146; nestin, CXCR4, PAX7, and FAP in CD146+ MIPCs (day 5 of culture), SC-derived myoblasts (day 3 of culture), CD146+ BMSCs (day 7 of culture), and fibroblasts (day 14 of culture), blue - nuclei; green - CD146, nestin; red - nestin, CXCR4, PAX7, FAP, scale bar 50 μm, (n = 3)
