Fig 4. Wound healing process increases expression of Postn, Col1a1, and Fn1 in a mouse model.

(A-C) Quantitative RT-PCR analysis of (A) Postn, (B) Col1a1, and (C) Fn1 mRNA expression in wound tissue removed from nude mice (n = 6) at 4, 7, 10, or 13 days after injury. Intact skin (0 days) was examined as a control. Data are means ± SD from one experiment representative of three independent experiments. *P < 0.05, **P < 0.005 vs. intact skin.
