The distribution of the cell surface molecules M6 and L1 was studied using the immunohistochemistry and in situ hybridization in the developing and adult mouse retina and optic nerve. L1 is a cell adhesion molecule while M6 is a cell surface molecule homologous to the myelin protein proteolipid protein (PLP/DM20). Although both molecules were expressed in retina and optic nerves of embryonic and neonatal mice, our studies show that their patterns of postnatal expression are quite different. While L1 continues to be expressed in optic axons throughout adulthood, expression of M6 on optic axons declines after birth and instead becomes strongly expressed on Muller glial endfeet and in the inner plexiform layer. The modulation of these molecules after birth could provide clues to changing cell-cell interactions occurring in the proximal portion of the optic pathway.
