Neural progenitor cells have different modes of division. A. Temporal sequence of neurogenesis in the mouse cerebral cortex. Neurons begin to accumulate in the cortical plate (CP) during the last 5 days of embryonic development. Within the cortical plate neurons populate the deep layers before settling in the superficial layers. (MZ, marginal zone; PP, preplate; SP, subplate; IZ, intermediate zone; SVZ, subventricular zone; VZ, ventricular zone; WM, white matter.) B. Asymmetric and symmetric modes of cell division. A progenitor cell (P) undergoes asymmetric division to generate a neuron (N) and a glial cell (G) (left). A progenitor undergoes and asymmetric division, giving Principles rise to another progenitor and a neuron. This mode of division contributes to the Source:cell Differentiation Survival of Nerve Cells, of Neural Science,cell Fifth Editon generation of neurons at early stages of development, and of glial cells at later stages, typical of many regions of the central nervous system (middle).
