Changes in the Distribution of Cell Contacts and Mitotic Cycle Disturbances in Cells of the Allograft of Rat Embryonic Neocortex

摘要

Morphological changes in the allograft of rat anterior cerebral vesicle at the early stages after transplantation into the peripheral nerve of an adult rat were studied by immunohistochemical methods. Immunohistochemical reaction to bromodeoxyuridine showed that the delay of mitotic division in neural stem/progenitor cells in the grafts occurred during S/G2 stage. In transplants of rat embryonic neocortex (E13), changes in the cell cycle of neural stem/progenitor cells in 3 h after transplantation into the nerve correlated with abnormal distribution of adherens junctions and interkinetic nuclear migration.
