| Emergence IPL | St38 (E8.5) | HH31 (E7) | Drenhaus et al. (2007) | |
| Emergence OPL | St39 (E9) | HH34 (E8) | ||
| Hatched retina | Proliferative activity | Abundant PCNA‐positive nuclei both in the CMZ and outer region of the INL in the central and mid‐peripheral retina | Sparse PCNA‐positive nuclei in the CMZ. A few PCNA‐immunopositive nuclei in the ONL of the central and mid‐peripheral retina | Fischer & Reh, (2000) |
| Abundant pHisH3‐positive cells both in the CMZ and scleral surface of the central and mid‐peripheral retina | Sparse pHisH3‐positive cells restricted to the CMZ |
