Pluripotent derived neurones. Coloured scanning electron micrograph (SEM). Human neurons engineered from induced pluripotent stem cells (iPSCs) through Neurogenin 2 (Ngn2) overexpression are widely used to study neuronal differentiation mechanisms and to model neurological diseases. These Ngn2-induced neurons (Ngn2-iNs) functionally mature into morphologically complex and electrophysiological active neurons.
