I would like to propose a new AO term: ectomesenchyme

definition: cell population arising from the cranial neural crest and which cells populate a series of pharyngeal arches from which develops the support skeleton of the jaw and gills.

Ectomesenchyme develops from:
cranial neural crest (ID: ZFA:0001194)

pharyngeal skeleton (ID: ZFA:0001216): Develops from ectomesenchyme.

Based on gene expression, the ectomesenchyme would appear around 15.5 hpf in zebrafish.

      This publication is about trunk neural crest and fin mesenchyme.
      However, I didn't find any information about the existence (or not) of ectomesenchyme from cranial neural crest (which will give rise to the pharyngeal arches).

      From the introduction of the paper:
      "[...] experiments have provided considerable evidence that, in addition
      to melanocytes and cells of the peripheral nervous system, anterior
      dorsal neural folds form cranial ectomesenchyme during
      neurulation. From this population arise skeletogenic, odontogenic
      and connective tissues of the craniofacial skeleton"

      Therefore, the term ectomesenchyme appears to still be needed.

      (sorry for the delay of my answer, the e-mail ended in my junk mail.)

    should this not be related to ZFA:0000787 ! mesenchyme derived from head neural crest

    as it is in uberon?
