Immunoreactive Substance P is localized in the intramural neural plexuses of mammalian intestine, and in endocrine cells in the intestinal mucosa which have now been identified as enterochromaffin (EC). The presence of a neurotransmitter peptide in these cells favours the hypothesis of their neuroectodermal origin.
免疫反应性P物质定位于哺乳动物肠道的壁内神经丛以及现已被鉴定为肠嗜铬细胞(EC)的肠黏膜内分泌细胞中。这些细胞中存在神经递质肽支持了它们起源于神经外胚层的假说。
