Endoglin (CD105) is a membrane protein involved in the TGF-beta receptor signalling pathway with predominant expression by proliferating endothelial cells. The aim of this study is to analyze the expression of Endoglin in choroidal neovascularization membranes (CNVM) and to compare it to the overall proliferative status of CNVM. Thirty surgically excised(More)
