神经干细胞增殖、迁移及分化调控机制的研究

Mechanism of proliferation migration and differentiation of neural stem cells

神经干细胞能够不断增殖、迁移,并具有分化成神经元、星型胶质细胞和少突胶质细胞的能力,神经干细胞的这种特性为研究中枢神经系统退行性疾病及损伤后功能恢复奠定了基础,也为法医病理学死后时间和尸体损伤推断的研究提供了新的机遇。本文对神经干细胞的分布、生物学特性、鉴定、增殖、分化与迁移的影响因素,及其在治疗中枢神经系统疾病和法医病理学中的应用前景作一综述。

Recent researches have showed that neural stem cells be isolated not only in the embryonic nervous system but also in adult nervous system. Neural stem cells have some capacity for self-renewal, migration and can differentiate into neurons, astrocyte and oligodendrocyte. This provides a basis in therapy of degenerative diseases and functional recovery of the central nervous system injury. Also helps in the study of determining the postmortem interval （PMI） and postmortem injury. Distribution, biological characteristic, identification and the factors effecting the proliferation, differentiation and migration with reference to therapy of neural stem cells and applications in forensic pathology are reviewed.
