Figure 7 Organized skeletal muscle cells. Treated area in a grafted sheep at two months after transplantation. (A) (x40) High density of grafted cells on traversal section and surrounded by fibrous tissue (H&E stain; bar = 100 µm). (B) (x300) Skeletal myotubes (SM) organized in parallel with multiple peripheral nuclei (*) and abundant myofilaments (H&E stain; bar = 150 µm). (C) Section of an engrafted scar area at two months after transplantation. Immunostaining for the fast isoform of the beta myosin heavy chain (My 32; bar = 200 µm). (D) To a serial section, immunostaining for the slow isoform of beta myosin heavy chain (NOQ7; bar = 200 µm).
