Percentage of tetraploid neurons in the cerebral cortex of wild-type and p75NTR−/− mice. A, Quantification of neuronal tetraploidy in the cerebral cortex of P0 and 2-month-old mice. The levels of tetraploidy in NeuN-positive nuclei were reduced in the cerebral cortex of p75NTR−/− mice. B, Quantification of neuronal tetraploidy in the cerebral cortex of P0 and 2-month-old mice. The levels of tetraploidy in CTIP2-positive nuclei were reduced in the cerebral cortex of p75NTR−/− mice. *p < 0.05 (Student's t test).
