It is widely known that during the development of nervous system, the synapse between neurons and target tissues plays an important role in the survival and maturation of neurons because target tissues or target cells can produce and secrete many kinds of neurotrophic factors and neuroinductive factors which can promote the growth, differentiation and migration of innervating neurons.

在神经系统发育中，神经元与相应靶组织建立的突触联系，是神经元存活和分化的关键因素，因为靶组织或靶细胞可以合成、分泌多种神经营养因子和神经诱向因子，促进支配神经元的生长、分化和迁移。

MNSFP was a previously identified novel implantation-related factor that needed to be further investigated in our lab, and is a lymphokine produced by suppressor T cell.

MNSFD是本实验室正在研究的另一个新发现的着床相关因子，它是一种由抑制性T细胞合成的具有非特异性免疫抑制作用的淋巴因子，因其能抑制IL-4的分泌和Th2细胞的产生，所以推测其可能与母胎间免疫耐受的形成有关，但有待于研究证实。

objective the aim of this study is to investigate the expression and the distribution of the nerve growth factor during the period of neural tube development of human embryo.method early development of neural tube was studied in human embryos about 35 gestational days by using immunocytochemical abc technique.result there were ngf immuno-positive substances in the cytoplasm and nuclei of neuroepithelial cells in the ventricular zones of neural tube.in the intermediate zone of neural tube,ngf immunoreactivity was detected in the nuclei of some neurons,or the processes of other neurons which contained no ngf-immunoreactive substances in their nuclei;the expression pattern of ngf in the marginal zone of neural tube was similar to that of the intermediate zone.the density of ngf-immunorecative particles was higher on the rostrum side of neural tube than on the caudal side.the ngf immuno-positive cells were also observed among the somites of embryo under the neural tube.conclusion these results suggest that ngf was an important signal molecule to induce neural tube differentiation,and that ngf may play a significant role in regulation of the biological function of neurons in developing neural tube.
