| Description | The presence of laminin-1, collagen-IV, a6 and b1 integrin chains was detected by indirect immunohistochemistry using biotin/streptavidin/HRP or gold-conjugated secondary antibody at the light and electron microscope level, respectively. Cryo-treated segment of the peripheral stump without living Schwann cells (S-100-) did not display immunoreactivity for laminin-1 and integrin's chains, while the migrating Schwann cells in the marginal regions were immunostained for the antigens. Isolated acellular nerve segments protected from migration of Schwann cells (S-100-) exhibited laminin-l-, b1-, and a6- integrin chains immunoreactivities. Position of the basal lamina was verified by collagen-IV+ immunoreactivity. Results indicate that presence of the laminin in the peripheral nerve is related with living Schwann cells. |
