High magnification view of endothelial cells in the Choriocapillaris

These are high magnification views of choriocapillaris. In the upper images, red blood cells remained in the vessels. In the lower images, we can see the borders and fenestration of endothelial cells. Area of fenestration is 0.5 or 1 µm away from the border. The knobs or leave shaped borders of the endothelial cells overlap with each other.
