Abstract

The expression of C1 and M1 antigens was studied by indirect immunofluorescence methods in histological sections of peripheral nerves and ganglia of C57BL/6J mice during development and regeneration. In sciatic nerves of adult mice, C1 but not M1 antigen is found in vimentin- and glial fibrillary acidic protein (GFAP)-positive Schwann cells. A similar distribution is also seen in trigeminal nerve, dorsal root and superior cervical ganglia, and olfactory nerve. In all cases vimentin-positive structures outnumber GFAP- or C1 antigen-positive ones. At birth, C1 antigen and vimentin are expressed in sciatic nerves, but GFAP is not yet detectable. M1 antigen cannot be detected in Schwann cells. In monolayer cultures of neonatal mouse dorsal root ganglia, C1 antigen is expressed in a fibrillary staining pattern in some, but not all morphologically identified Schwann cells. In vitro, M1 antigen is not detectable in Schwann cells. After lesioning sciatic nerves of adult mice by cut or crush, detectable levels of C1 antigen rise after 4-6 days: The number of immunofluorescently labeled structures and their relative intensities are drastically augmented, first distally more so than proximally, over control values from non-lesioned, i.e. contralateral nerves. A similar augmentation is also observed for vimentin and GFAP. M1 antigen expression does not reach detectable levels in Schwann cells under these conditions. The increased detectability of C1 antigen persists up to 150 days after lesioning, the longest time period tested.
