Histological assessment of skeletal muscle wound healing.

<p>Hematoxylin & Eosin staining of VML affected TA muscle at A) 2 weeks and B) 8 weeks post-injury from the 50% and 100% MG treatment groups exhibit similar results at 8 weeks post injury. The expansion test group (50% MG + 50% UBM) presents greater muscle fiber presence relative to UBM alone, but exhibits greater deposition of non-contractile tissue in the defect space relative to the MG alone groups (50% MG, 100% MG). Scale bars represent 200 and 1000 microns at high and low magnification, respectively.
