Fig. 4. Impaired migration of the ENCCs in RET S697A mutant mice.
Whole-mount in situ hybridization with riboprobe specific for RET on the
developing guts in wild-type (A-C) and homozygous RET S697A mutant mice
(D-F) at E11.5 (A,D), E12.5 (B,E) and E14.5 (C,F).
(A'-C',D'-F') show
high-power views of the front of the migrating RET positive ENCCs in A-F,
respectively. Arrows, the front of the migrating ENCCs; arrowheads, cecum;
asterisks, terminus of the hindgut. Scale bars: 500 µm.
