It is shown here that hedgehog polypeptides possess novel activities beyond phenotype specification. Using cultures derived from the embryonic day 14.5 (E14.5) rat ventral mesencephalon, we show that hedgehog is also trophic for dopaminergic neurons and other neurons which are sensitive to exotoxicity.

多肽具有超越表型规范的新活性。我们使用从胚胎14.5天(E14.5)的大鼠腹侧中脑衍生的培养物,展示了刺猬对
多巴胺能神经元和其他对外毒性敏感的神经元也具有营养作用。
