Unimpaired repair of cutaneous ear wounds in PAK1^−/− mice.

<p>A) Recovery of 2.0 mm ear punch wounds is represented by (Area _{day X/}Area _{day 0}) ×100. There was a notably larger but not statistically significant wound diameter in PAK1^−/− mice compared to PAK1^+/+ mice on day 7. B) The wound edge was stained with Mason's trichrome and shows a very similar wound closure between the two groups by day 28. n = 3 for both PAK1^+/+ and PAK1^−/− groups.
