Scanning electron microscopy of ADSC/Mb, BMSC/Mb, and C2C12 on PCL-collagen I-nanoscaffolds after long-term myogenic differentiation. After 28 days of myogenic differentiation, (a) ADSC/Mb were confluent, covering almost the entire surface of the scaffold. b BMSC/Mb were less densely spread on the scaffold. c C2C12 cells showed parallel alignment on the scaffolds with myotube-like structures
