FIG. 6.
Cell tracing after transplantation. (A) To trace WJ-MSCs after their transplantation, they were labeled with chloromethylbenzamido dialkylcarbocyanine before transplantation. Labeled cells loaded into PHBVHHx scaffolds were transplanted into liver-injured mice after 30 days of CCl4 injection. Scaffolds were removed after 14 and 30 days of transplantation. Fluorescent cells in scaffolds were observed before and after transplantation. (B) Scaffold sections were also examined by HE staining. Stained cells in scaffolds were observed after 14 and 30 days of transplantation of scaffolds loaded with WJ-MSCs. Color images available online at www.liebertpub.com/tea
