endodermiin
Endodermiin is a hypothetical regulatory factor proposed in discussions of vertebrate endoderm development. The term is not associated with a confirmed, widely cited molecular entity in the standard developmental literature, and there is no consensus on its existence. In theoretical models, endodermiin would represent a secreted signaling or cell-intrinsic factor linked to endoderm specification, named for its purported association with endoderm lineage commitment.
In proposed frameworks, endodermiin would be produced by early endoderm progenitors and act in a paracrine
Because endodermiin lacks experimental validation, it remains a speculative concept. Critics note that attributing uncharacterized signals
