Immunostaining for αv-integrins on the cell surface of hMVEC stimulated with bFGF/TNF-α.
After an incubation period of 5 days with bFGF/TNF-α, the fibrin matrices were sectioned and endothelial cells were stained for αv-integrins. Arrows point to endothelial cells present in the monolayer on top of the matrix and to cells in the capillary-like tubular structure in the fibrin.
