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.
Consistent with previous findings (Kim and Li, 2004), we found that flp-20 is expressed in the TRNs (ALM, AVM, PLM, PVM), along with a few other neurons (ASE, LUA, and PVC).
wdr-5.1 was nuclear-localized in Y/PDA throughout transdifferentiation.In some cases faint additional WDR-5.1::GFP staining was observed in the cytoplasm.
