part of part of marginal zone of embryo embryonic tissue noninvoluting endocytic marginal cell cluster UBERON:2001126 NEM ZFA:0001126 noninvoluting endocytic marginal cells This class was sourced from an external ontology (teleost_anatomy). Its definitions, naming conventions and relationships may need to be checked for compatibility with uberon The NEM cell cluster lies in a superficial position of the dorsal blastoderm margin encompassing EVL cells and one or two layers of underlying deep cells. Unlike other marginal blastomeres, cells in this cluster do not participate in involution. Cooper et al, 1996.
