The egl-27 reporter is expressed in the Y cell in the 1.5-fold embryonic stage as well as during the L1 larval stage, which precedes the initiation of Y transdifferentiation.
cho-1 is expressed in terminally differentiated AIA interneurons. Reporter fusions to the unc-17/cha-1 locus and to the choline reuptake transporter cho-1 are expressed in IL2 neurons.
Ce-cdd-2 first appeared in the 8 h sample (late L1), and then was more or less constitutively expressed up to the 34 h sample (young adult), after which expression increased in the 3640 h samples.
