At 2 weeks following I/R injury, human CD34+, and human CD31+ vessels were already readily detectable in N-DVP-injected retinae at significantly higher rates than primed DVP-injected retinae in the intima of murine host ischemia-damaged capillaries located in the ophthalmic artery distribution of the deep neural retinal layers. The gene discussed is PECAM1; the disease is ischemia.
