title: VIP-like immunoreactivity in the suprachiasmatic nuclei of a mutant anophthalmic mouse.
abstract: The suprachiasmatic nuclei (SCN) of mutant anophthalmic (strain ZRDCT-An) and sighted control mice was examined using light microscopic methods for cytoarchitecture and immunocytochemistry for vasoactive intestinal polypeptide (VIP). The SCN of the anophthalmic mice were asymmetrical, and quite variable in cytoarchitecture. Immunocytochemistry for VIP revealed strong staining of cells and fibers. Within the SCN, the distribution of VIP-immunoreactive cells was more diffuse in anophthalmic mice than in the controls; immunoreactive neurons were frequently observed in ectopic locations in the mutant animals.
