Fig. 5. Cdx4 and Cdx1a function redundantly. (A-D) The pdx1
domain is further expanded in zebrafish kgg mutants and siblings
following morpholino (MO) knockdown of cdx1a. (E-H) The
insulin domain is further expanded, and β-cells show a delay in
converging to form the islet, following cdx1a knockdown in
kgg mutants and siblings. Numbers indicate somites. Dorsal views.
