Decreased angiogenesis in DDAH1 KO mice.

<p>(A) H&E staining of Matrigel plugs. Representative images show fewer microvessels in the KO mice (20x magnification). Arrows show microvessels. (B) The angiogenic response was evaluated by measurement of hemoglobin content in the Matrigel plugs after two weeks. Each group consisted of four animals and the experiments were repeated 3 times (*p<0.05).
