Nolz1 is expressed in subsets of postmitotic spinal MNs.
(A-H) In situ hybridization of Nolz1 mRNA expression on
transverse sections of embryonic chick spinal cords. (I-R) Confocal
micrographs showing analysis of Nolz1 protein expression as compared with
molecular markers of specific spinal motor columns. Arrows mark Nolz1 and Lim3
coexpressing MNs. (S) Summary of Nolz1 expression in relation to motor
column development. The dashed orange line indicates transient Nolz1
expression. MMC, median motor column; MMCm, medial division of the MMC; MMCl,
lateral division of the MMC; LMC, lateral motor column; LMCm, medial division
of the LMC; LMCl, lateral division of the LMC; CT, column of Terni.
