APUD Cells

Medical Definition:	Cells derived from primitive cell types in the neural crest. During ontogeny they migrate to the foregut and specific locations of the neuroendocrine system. Properly located these cells form part of the normal hormone producing tissues of the neuroendocrine system. If misdirected these cells may become hyperplastic, adenomatous, or malignant (cf. APUDOMA).
Guide Notes:	named APUD from Amine Precursor Uptake & Decarboxylation; use term only when used by author; A 11 qualif
