TLDR Gene knockout mice developed scars similar to human hypertrophic scars, useful for studying scar progression.
The study compared hypertrophic scars in different genetically modified mice strains (TCRαβ-/-γδ-/-, RAG-1-/-, and RAG-2-/-γc-/-) by grafting them with human skin and analyzing the resulting scars over time. The results showed that these mice developed firm, elevated scars with histologic and immunohistochemical similarities to human hypertrophic scars, unlike the autografted controls which did not show pathologic scarring. The knockout mice also demonstrated scar remodeling capabilities, suggesting that these models may better represent the natural history of human hypertrophic scars.
