The basement membrane of epithelial cells is 40-60 nm in thickness and is made up of Type IV collagen and laminin secreted by basal cells. The membrane is semipermeable, meaning it allows only certain substances to pass through it. defined a network of 222 human proteins, and the related genes in other species, that constitute basement membranes. Cell-matrix interactions between keratinocytes and the epidermal basement membrane provide key positional and . Increasing evidence suggests that BMs are unique signal input devices that likely fine tune cellular function. But more recent studies have disregarded diploblast-homoscleromorph group, so other sponges may have lost it (most probable) or the origin in the two groups may be separate. This thin layer serves as a boundary with connective tissue and as a substrate to which epithelial cells are attached. These layers are separated by a layer of material called the basement membrane. It functions to support the epidermis and endothelial tissue attached to it and also assists in filtration.
