(A) Histologic appearance of the acellular xenograft at 7 days post surgery. A dense cellular infiltrate consisting of mostly mononuclear cells was seen surrounding and within (arrows) the layers of the acellular xenograft (blue staining, bracket) at 7 days post surgery. (B) Histologic appearance of the acellular xenograft at 28 days post surgery. The acellular xenograft was no longer discernable by 28 days post surgery and was replaced by fibroblasts, blood vessels (asterisks), aligned collagen and small islands of skeletal myoblasts (arrows). The red staining tissue bundles at the bottom of the image represent the underlying transversalis muscle (Masson's trichrome, 200×).
