A statistical summary of the cell marker staining results.

For Islet1+ACs, zn8+ GCs, and Prox1+ & Islet1+ HCs, their numbers were counted and normalized by the corresponding retinal area. The mean (), standard deviation (s) and the number of embryos (N) for each group at each stage are listed, and the corresponding U- and p-values from the Mann-Whitney test computed. The figure numbers of the corresponding immunostaining pictures are also listed.
