OBJECTIVE: To genetically screen zebrafish mutants with defective liver, intestine and gallbladder development.
Methods: Wild-type zebrafish were mutagenized with ENU and the classical F2 generation screening was performed. Whole embryo in situ hybridization using lfabp as a probe and BES-H2O2-Ac fluorescent dye were used to detect the phenotypes of early embryonic liver, intestine and gallbladder of zebrafish respectively. .
RESULTS: Twenty-three zebrafish digestive organ development-deficient mutant strains derived from 14 F2 families were screened out of 128 mutant genomes, and they were divided into 6 types according to phenotype.
Conclusion: The developmental regulatory mechanisms of zebrafish liver, intestine and gallbladder have similarities and differences.
