Abstract:
By using biochemical and immunochemical approaches, we have isolated a rat spermatocyte surface protein of an apparent molecular weight of 80 kd involved in spermatocyte-Sertoli cell recognition in culture. Preliminary characterization of such a molecule has demonstrated that 1) it is a nonintegral membrane component; 2) it possesses a small amount of N-linked oligosaccharides of the high mannose type; and c) it is a stage-specific molecule, being present only in middle-late pachytene spermatocytes.
