Fig. 1. Genetic screen for regeneration and identification of the ncp
mutant. (A) Illustration depicting mutagenesis and screen for
temperature-sensitive fin regeneration mutants. (B) Whole-mount wild-type and
ncp caudal fin regenerates at 2 and 7 days postamputation. The
ncp mutant showed a clear defect in fin regeneration by 7 days
postamputation. Arrows demarcate amputation plane in each photo. Original
magnification is 15x.
