Revised lineage of larval photoreceptor cells in Ciona reveals archetypal collaboration between neural tube and neural crest in sensory organ formation
Dechorionated Ciona embryos exhibit abnormal patterning of the brain. Fates of neural plate cells were determined in nondechorionated Ciona embryos. Photoreceptor cell lineages of the larval ocelli are extensively revised. The ocellus pigment shows prototypic contribution of neural crest to a sense organ.
