Fig. 4From: In vivo conversion of rat astrocytes into neuronal cells through neural stem cells in injured spinal cord with a single zinc-finger transcription factorThe differentiation of adult astrocyte-derived induced neural stem cells (iNSCs) in vitro. a Phase-contrast images of astrocytes (AST), induced neural stem cells (iNSCs) at passage 5 (P5), and 3 weeks post-differentiation (3 WPD). b Immunostaining of iNSCs differentiated into NF200 and Gaba-A receptor-positive neurons, Glast and glial fibrillary acidic protein (Gfap)-positive astrocytes, and Olig2-positive oligodendrocytes. Nuclei were counterstained with DAPIBack to article page
