Basement membrane location: Basement membrane (BM) is ubiquitous in the human body and is located adjacent to the epithelium, endothelium, and parenchymal cells including muscle, adipose as well as nerve cells. It is involved in many vital physiological processes and is found in many organ barriers including the brain, retina, kidney, intestine, and lung. The schematic displays examples of some of the vital organs where the BM can be found. This includes the underlying areas of the epithelium and endothelium, where it supports and physically separates the different cellular layers. Created with Biorender.com
