有证据表明,外周神经元具有促生长作用,如一旦损伤支配肢体的外周神经,则妨障蝾螈的肢体再生功能,完整的感觉神经支配对于大鼠的角膜损伤愈合是必不可少的;近年不少实验资料表明:某些神经肽可调节细胞的增殖活动,如NKA和SP刺激人成纤维细胞和大鼠平滑肌细胞的增殖。降钙素基因相关肽作 There is evidence that peripheral neurons have the role of promoting growth, such as once the limbs damage peripheral nerve control limbs, barrier Newt limb limb regeneration, complete sensory innervation of corneal injury in rats is essential for healing; in recent years Many experimental data show that: some neuropeptides can regulate cell proliferation activities, such as NKA and SP stimulate human fibroblasts and rat smooth muscle cell proliferation.
