Fig. 2. The floorplate is reduced in width in both mol-/- and
smu-/- embryos. (A-C) Lateral views of the floorplate in
the trunk of living wild-type, mol-/- and
smu-/- embryos. Cuboidal floorplate cells are present in
all embryos, although the cells are increased in size in
mol-/-. (D-F) Dorsal views of foxa expression in
the hindbrain floorplate. In the mol-/- and
smu-/- mutants, expression is reduced from a six cell wide
band to a one to three cell wide band (black lines). Additionally, gaps of
expression are present in the mol-/- mutant. (G-I) Dorsal
views of foxa2 expression in the head. Midline expression is narrow
in both the mol-/- and the smu-/-
mutant, and additionally is patchy in the midbrain and hindbrain in the
mol-/- mutant. e, endoderm; fp, floorplate; hy, hypochord;
nc, notochord; ZLI, zona limitans intrathalamica.
