Neural stem cells (NSCs) will proliferate as progenitors a few times even after the complete growth medium is replaced with the appropriate differentiation medium. If the cells reach 90% confluency, it might be necessary to split the cells at a 1:2 ratio. However, do not split the cells once they reach day 9-10 of differentiation when they can get damaged during the passaging process.
IMPORTANT! Do not expose cells to air at any time after they have differentiated into neurons.
