Raldh2 (green) and Islet1/2 (red) proteins on transverse spinal cord sections.
(E-F) Raldh2, Islet1 and Lim1 transcripts on adjacent
transverse spinal cord sections, at the posterior LMC level. The
Islet1 and Lim1 subpopulations within the LMC are marked by
brackets and vertical lines, respectively.
