Fig. 9 Midline expression of shh in ntl mutants (A) and cyc;ntl double mutants (B) detected by RNA in situ hybridization. Left side views of the trunk of whole-mounted 24-hr embryos, with anterior to the left and dorsal to the top. In ntl mutants, shh transcripts are present in floor plate (white arrowhead) and in a few cells beneath the spinal cord (arrow). cyc;ntl double mutants only show floor plate labeling, present in approximately a 1-cell-wide row. Scale bar, 25 um.
