Fig. 7From: In vitro induction of human embryonal carcinoma differentiation by a crude extract of Rhazya stricta Differentiation of NT2 cells into postmitotic neurons when incubated with 10 μM RA. (A1) On day 4, the morphology of NT2 cells with 10 μM RA had begun to change. (A2) On day 12 and (A3) day 21, the NT2 cells showed neuronal morphology with an extended network over the surface of the culture. (B1, B2 and B3) Vehicle control (0.001% DMSO) cells maintained their morphology over 21 days. Scale bar, 500 μm. Magnification (10×). Arrows indicate neuronal morphology with extended networkBack to article page
