Figure 4From: Locally existing endothelial cells and pericytes in ovarian stroma, but not bone marrow-derived vascular progenitor cells, play a central role in neovascularization during follicular development in miceDouble immunostaining for CD34 (a vascular endothelial cell marker) and GFP (a bone marrow derived-cell marker) in the parabiosis model. Blue shows CD34, and brown shows GFP. Double-positive cells are indicated by arrows. T: theca cell layer, G: granulosa cell layer. Scale bars; 50 μm.Back to article page
