“…This cell lineage, which is known as the trunk lateral cells, expresses the HNK-1 epitope as well as the Twist, FoxD, AP2, and Myc orthologs ( Jeffery 2006;Jeffery et al 2008). Further studies are necessary to determine unequivocally if these cells are derived from the neural plate border, neural tube, or other tissue (Hall and Gillis 2013). In an intriguing recent study, Abitua et al (2012) showed that a lineage a9.49 in Ciona intestinalis expresses ID, Snail, ETS, and FoxD, as well as melanogenic genes like MITF, TYR, and TYRP.…”
