Based on known roles of the extracellular matrix in other tissues, the IPM is thought to have several prominent functions including serving as a receptor for growth factors, regulating retinoid transpo, paicipating in cytoskeletal organization in surrounding cells, and regulation of oxygen and nutrient transpo
