In the early neurulae (E4), the lamprey ZicA homolog is expressed throughout the neural plate, overlapping MsxA at the neural plate border.
Interestingly, lamprey neural crest specifier genes exhibit a biphasic mode of expression: a subset of them are expressed early in the neural plate border, while others are found only in the bona fide neural crest progenitors of the E5.5-E6 neurulae and later in the migrating/differentiation crest.
Early neural crest specifiers, such as AP-2, Id, Snail, or c-Myc/n-Myc, initiate expression in the E4.5 lamprey neurulae, shortly after the onset of neural plate border specifiers, MsxA, ZicA and Pax3/7, and their expression domains overlap in the neural plate border.
