Figure Caption

Fig. 5 Lack of Dnmt1 activity does not arrest the cell cycle. (A, B) Confocal planes showing EdU incorporation in 84 hpf WT (A) and dnmt1 mutant (B) Tg(ptf1a:EGFP)^jh1; Tg(ins:dsRed)^m1081 larvae. (C, D) Phospho-histone 3 (late G2 interphase through anaphase marker) and Dnmt1 staining of 84 hpf WT and dnmt1^s904 mutant Tg(fabp10:DsRed; ela:GFP)^gz12 larvae. (C′, D′) Dnmt1 channel only. (E) EdU incorporation rate in pancreatic acinar cells, hepatocytes, and intestine of dnmt1 mutants appears indistinguishable from WT (p = 0.87, p = 0.52, p = 0.91, respectively). Error bars = SEM. Significance assessed by Student′s t-test. (F, G) H2BRFP label retention analysis of endodermal organ forming region in WT Tg(gut:GFP)^s854 animals at 52 (F) and 84 (G) hpf. The ventral pancreatic bud (vpb) is demarcated by a dashed line. H2BRFP is diminished in the highly proliferative vpb relative to the dorsal pancreatic bud during outgrowth (F) and pancreas tail formation (G). (F′, G′) H2BRFP (red) and Ins (blue) channels only. Primary islet (pi).
