Figure 6: Induction of NSCs from spinal astrocytes by SOX2 in culture.
From: In vivo conversion of astrocytes to neurons in the injured adult spinal cord

(a) Experimental scheme. (b) Immunocytochemistry confirming the astrocyte identity of cultured tdT+ cells. (c) Representative micrographs of neurospheres from spinal astrocytes infected with the hGFAP-GFP-T2A-SOX2 lentivirus. (d) Frequency of neurosphere-forming cells from spinal astrocytes infected with the indicated lentivirus. Secondary spheres were quantified at 7 days after plating (mean+s.d.; n=5; *P<0.01 by Student’s t-test). (e) Nestin (NES) expression in SOX2-induced neurospheres. (f) Multiple lineage differentiation of SOX2-induced secondary neurospheres. Immunocytochemistry was performed 6 days after plating dissociated single cells. Scale bars, 50 μm (b), 200 μm (c), 60 μm (e) and 40 μm (f).
