FIG. 6.
α-SMA staining identifies stromal cells within the implant. Human α-SMA staining (brown) and counterstaining with H&E at (A) 7 days and (B) 14 days post-implantation. Arrows point to representative positive α-SMA around vessels, but prevalent positive staining is present in all implants that contain stromal cells at both time points. α-SMA, alpha-smooth muscle actin.
