FIG. 4.

LD muscle tissue morphology after VML injury and immediate repair with TEMR constructs. VML-injured LD muscles that were either not repaired [(A) and (E)] or repaired with TEMR-1SP [(B) and (F)], TEMR-1SPD [(C) and (G)], or TEMR-2SPD [(D) and (H)] TEMR constructs were retrieved 1 month (A–D) and 2 months (E–H) postinjury and stained using Masson's trichrome (Red=tissue, Blue=Collagen, and Black=Nuclei). *Marker of area of initial injury [(A) and (E)] or presumptive BAM collagen deposition [(B–D) and (F–H)]. Images are 200× magnification with the scale bar=50 μm. Color images available online at www.liebertonline.com/tea
