Figure 3From: Regulation of trophoblast beta1-integrin expression by contact with endothelial cellsEffect of temperature and incubation time on trophoblast β1 integrin expression. Trophoblasts were cocultured with endothelial cells at 37°C for 2 h (A and B) or at 4°C for 24 h (C and D). Staining for β1 integrin is shown in (A) and (C). Respective identical fields viewed to show cytokeratin staining (red) are shown in (B) and (D). The bar represents 20 μm.Back to article page
