Figure 1: Engraftment potential of ES-derived myogenic precursors following transplantation in the dKO:mdx/utrn-/- dystrophic mouse model. Cryosections from TA muscles of two representative mice show staining with dystrophin antibody in muscles that had been injected with PBS (A, C) or myogenic progenitors (B, D). DYSTROPHIN and DAPI are shown respectively in red, and blue. Scale bar is 50 Ám.
