WebJan 17, 2024 · The basement membrane is a thin sheet of fibers called the basement membrane that separates the dermis and epidermis. It controls the traffic of cells and molecules between the dermis and epidermis and the release of cytokines and growth factors during wound healing. The basement membrane is located in almost every tissue of the body. It can lie beneath endothelial and epithelial cells; separate cells from the underlying connective tissue; or surround cells, like muscle (myofibrils), fat, and nerve cells (neurofibrils).
