Changes in expression of inflammatory factors and collagen after ANBP treatment.

<p>mRNA levels were detected by quantitative RT-PCR at 4, 7, 14 and 28 days post-wounding. mRNA levels are shown for: (A) IL-1; (B) TNF-α; (C) Col I; (D) Col III. Expression levels were calculated using standard curves and normalized to expression level of β-actin as an endogenous reference gene. * <i>p</i><0.05, ** <i>p</i><0.01.
