Evaluation of wound healing under NIR photothermal therapy

(A) Images of applying different scaffolds in rat wounds.

(B) Schematic diagram of autologous skin transplantation in rats under NIR photothermal treatment.

(C) Representative images of survival at each time point after full-thickness skin graft injury: A. The edge of the graft is encircled by a red dotted line; B. vascularization images of implanted stent materials.

(D) H&E staining results of rat viscera.

(E) H&E staining of graft sections collected at different time points from varying hair follicles (black star) and implants (black arrow).

(F) Shrinkage of grafted skin on days 3, 7, 14, 21, and 28 after injury (∗∗p < 0.01).

(G) Quantitative analysis of skin shrinkage rate (∗P<0.05, ∗∗P<0.01, ∗∗∗P<0.001).
