In vivo study of red fluorescence-labeled rat fibroblasts (rat dermal fibroblasts expressing TurboFP602 red fluorescent protein) adhesion on injured abdominal wall and cecum. (A) Schematic illustration showing red fluorescence-labeled fibroblasts applied to abdominal wall and cecum defects (with or without PCBAA protection). (B) Representative fluorescence images showing no significant red fluorescence-labeled fibroblast adhesion on the PCBAA-treated abdominal wall defects at 2 h, 1 d, and 4 d after the surgery, while abundant fibroblasts adhered onto the untreated wounds at 1 d and 4 d after surgery. (C) Quantification of fluorescent intensity in the region of abdominal wall defects as indicated in B. The results were presented as mean ± SD (n = 3). A two-tailed t test analysis was used for statistical analysis. **P < 0.01; NS, not significant.
