Expression of myogenic regulatory factors, Ki67, and NICD in CXCR4+BMCs(β-gal+) cocultured with myofibers for 5 days. a Localization of Ki67. b Localization of Myf5. c Localization of Myod1. d Percentage of CXCR4+BMCs(β-gal+) expressing Ki67, Myf5, and Myod1 attached to myofibers (n = 30). e Localization of Notch intracellular domain (NICD). f Localization of NICD in freshly isolated CXCR4+BMCs(β-gal+). g Percentage of CXCR4+BMCs(β-gal+) expressing NICD among cells freshly isolated from bone marrow-derived cells (fresh BMCs; n = 20) and after coculture with myofibers (p-t BMCs; n = 30). β-gal β-galactosidase
