Fig. 2 PGE2 Affects Embryonic Pancreas Outgrowth (A) In situ hybridization for trypsin, an exocrine pancreas-specific marker, following exposure to dmPGE2 or Indo reveals that embryonic pancreas size is regulated by PGE2. dmPGE2 increases exocrine pancreas size (57.6% embryos with an enlarged pancreas; n = 38/66), whereas Indo diminishes exocrine pancreas size (70.6% embryos with a smaller pancreas; n = 36/51). Dorsal view. (B) FACS quantification of GFP+ exocrine pancreas cells in elastase:GFP embryos at 96 hpf following exposure to dmPGE2 or Indo. dmPGE2 increases and Indo decreases the relative number of exocrine pancreas cells. (Data are represented as mean ± SEM; ****significant across treatment groups, ANOVA, p < 0.0001.)
