Fig. 1From: Myogenic differentiation of human myoblasts and Mesenchymal stromal cells under GDF11 on Poly-ɛ-caprolactone-collagen I-Polyethylene-nanofibers(a) Mb in P6 showed > 95% positive staining for the muscle-specific marker desmin. Human primary fibroblasts in P9 served as negative control (insert); (b) Mb in P6 showed formation of multinucleated myotubes (exemplarily marked with white arrows) after 7 days of myogenic differentiationBack to article page
