Fig. 4. Enhanced basal keratinocyte proliferation in hai1a mutant embryos occurs subsequent to epidermal cell aggregation. (A-D) Confocal images of ventral yolk epidermis of wild-type siblings (WT; A,C) and hai1a mutants (B,D) at 24 hpf (A,B) and 48 hpf (C,D), after BrdU labeling of proliferating cells (green) and anti-p63 immunolabeling of basal keratinocytes (red).
