the results indicate that the extracellular matrix gene expression profiles of schwann cells , perineurial cells , and fibroblasts are distinct : all three cell types are capable of expressing some of the genes for extracellular matrix components , such as type i and vi collagens , whereas schwann cells and perineurial cells may have the primary role in synthesizing basement membrane zone components , type iv collagen and laminin .
