obsolete forerunner cell group true forerunner cells UBERON:2000023 ZFA:0000023 dorsal forerunner cells incorrectly generalized to teleosts so being obsoleted. 'embryonic structure' and develops_from some 'noninvoluting endocytic marginal cell cluster' A group of cells that migrate at the leading edge of shield during gastrulation but do not involute. At the end of gastrulation, forerunner cells migrate deep into the embryo and organize to form Kuppfer's vesicle. Cooper and D'Amico, 1996. 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 DFCs
