Developmental changes of chick cerebellar cortex revealed by monoclonal antibodies.
Immunohistochemistry studies of the embryonic and newly hatched chick cerebellum were performed with 13 monoclonal antibodies (MAbs) raised against the embryonic chick optic nerve and a MAb which binds to cell nuclei. Neural MAbs differentially stained Purkinje cells, the external granular layer, molecular layer, internal granular layer, climbing fibers, basket cell axons, Bergmann glia and Ramón y Cajal's ansiform fibers. At the different developmental stages each component responded to MAbs differently. For example, staining of Purkinje cells with MAbs 23C10, 82E10 and 94C2 appeared on day 11 of incubation and disappeared sequentially after day 18. These results reveal molecular heterogeneity not only in cerebellar neurons but also at various developmental stages.
