Distribution of proliferating cells in the Main Proliferative Zone (MPZ).

A–H. Distribution of proliferating cells in the MPZ (A, B), RMS (C, D), CMS (E, F), and midlayer (G, H). Lateral view. Each EdU-labeled nucleus is shown as a colored dot with colors assigned according to Table 2 (A, C, E, G). Each EdU-labeled nucleus located in the RMS is shown as a lilac dot, in the CMS as a blue dot, and in the midlayer as a red dot (B, D, F, H). I–K. Pie chart showing the percentage of EdU-labeled nuclei located in different parts of the MPZ (I), CMS (J), and midlayer (K). Abbreviated names are given according to Table 2. 120 days-old mouse one hour post EdU injection.
