Fig. 2From: Nicorandil potentiates sodium butyrate induced preconditioning of neurons and enhances their survival upon subsequent treatment with H2O2 Sodium butyrate (NaB) treatment of neural stem cells (NSCs). a Treatment of NSCs with NaB decreased the rate of neurosphere formation whereas the rate of cluster formation was significantly increased as compared to the non-treated control cells (PÂ <Â 0.05). b Phase contrast image of neural clusters after treatment with NaB. c Phase contrast image of the derivative neurons after 10-day treatment with NaBBack to article page
