Basement membrane

All epithelia rest on a basement membrane, which consists of two components, the basal lamina, secreted by epithelial cells, and a reticular lamina, secreted by fibroblasts in the underlying connective tissue.  The basal lamina is, in turn, subdivided into lamina lucida and lamina densa.  Serosa  15,000x
