Figure 7.

Histological sections of cell-laden hydrogel modified allograft 9 weeks post-implantation revealed extensive mMSCs localized to the bone callus ($)/muscle (#) interface as well as extensive mMSC migration into striated muscle (white & red arrows). Transplanted GFP⁺ mMSCs were detected via hematoxylin staining (blue) and GFP⁺ fluorescence. Striated muscle was shown to auto-fluoresce and GFP⁻ mMSCs were shown to be undetectable in the GFP⁺ channel (scale bar = 150 μm).
