PCNA and F4/80 immunohistochemical expression after muscular injury.

Abstract

<p>WT: wild type, KO: knockout. (A) Immunohistochemistry of PCNA. (Scale bar = 50μm), (B) Quantitative analysis of PCNA-positive cells, (C) Immunohistochemistry of F4/80. (Scale bar = 50μm), (D) Quantitative analysis of F4/80-positive cells. (B and D) Both PCNA and F4/80 expression in p21KO mice at 3 days after injury were the highest (p < 0.05).</p
