TS14: branchial arch	Present	Regionally restricted	6D	Crabp1 positive neural crest cells were found streaming ventrally from the neuroepithelium at the top of the section into the second branchial arch.

Structure	Level	Pattern	Image	Note
TS13: future hindbrain	Present	Regionally restricted		Immunoreactivity appears as a single stripe throughout the full thickness of the neuroepithelium in the presumptive hindbrain region of the embryo before neural tube closure.
