Which one of the following is NOT true about ECM? O ECM is composed of an interlocking mesh of fibrous proteins and glycosaminoglycans. O ECM supports cell-to-cell communication and stem cell differentiation. O Proteoglycan complex has a unique bottle brush-like structure. It is positively (+) charged. It is composed glycosaminoglycans and carbohydrates that are attached to the proteins. O ECM is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells.
