nr5a2 is expressed in the developing endoderm and is required for exocrine pancreas formation. (A) Expression pattern of nr5a2 in the developing endoderm by in situ hybridization. nr5a2 appears in the developing liver bud (red arrow) by 30 hpf and the pancreas bud (blue arrow) by 36 hpf. After 84 hpf, it is expressed in the mature liver (red arrow) and exocrine pancreas (blue arrow). (B) Expression of nr5a2 in FACS isolated acinar cells from the Tg(trypsin:GFP) line at 72 hpf by qRT-PCR. (C) Expression of nr5a2 in FACS isolated hepatocytes from pooled Tg(fabp10a:GFP) embryos at 72 hpf by qRT-PCR (fold enrichment displayed as an average of technical triplicates). (D) Splice-site morpholino (MO) knockdown of Nr5a2 reduces the size of the exocrine pancreas by in situ hybridization for trypsin at 96 hpf. (E) nr5a2 MO injected embryos (96 hpf) have a reduced exocrine pancreas size (blue arrow) by histology and section in situ hybridization for trypsin (n=5). (F) FACS quantification of GFP+cells (% of control) from elastase:GFP reporter fish at 96 hpf demonstrates that MO knockdown of nr5a2 reduces the number of exocrine pancreas cells (n=20 per treatment; p<0.05; unpaired t-test). |
