Balance of differentiation and proliferation. This process ensures that an adequate amount of neurons will be produced. Neurons will be produced through (A) terminal symmetrical division or in a way that the (B) maintenance of the neural progenitor cell pool is ensured with the self-renewal of enough progenitors. Factors guiding each process are listed below. Legend to the right. NSC, neural stem cell; N, neuron; IP, intermediate progenitor; RG, radial glia; Post-transcriptional factors in blue in A and B; TF, transcription factors in red in A and B.
