BM interactions. Scanning electron micrograph showing the relationship between the BM (basal lamina), collagen fibrils, and migrating epithelial cells. Some of the epithelial cells (E) have been removed to expose the upper surface of the basal lamina (L). A network of collagen fibrils (C) interacts with the lower face of the lamina (Credit: Courtesy of the late Robert Trelstad).
