Additional file 1: of Transcriptional regulation of ependymal cell maturation within the postnatal brain

Lack of NFIX immunoreactivity in ependymal cells within postnatal Nfix −/− mice. Coronal sections of wild-type (A-C) and Nfix −/− (D-F) brains at P15 showing expression of vimentin and NFIX. In wild-type mice, vimentin labelled cells lining the lateral ventricles (LV) clearly expressed NFIX (arrowheads in A-C). In Nfix −/− mice, however, NFIX expression was absent in ependymal cells (arrows in D and F). Scale bar (in A): 30 μm. (TIFF 7739 kb
