    名词解释题
    neural stem cell,NSCs (神经干细胞)

    正确答案: 主要有两类:神经嵴干细胞(neuralcreststemcell,NC-SC)和中枢神经干细胞(CNS-SC)。NCSC为外周神经干细胞(PNS-SC),既可发育为外周神经细胞、神经内分泌细胞和Schwann氏细胞,也能分化为色素细胞(pigmented cell)和平滑肌细胞等。NSC一般是指存在于脑部的中枢神经干细胞(CNS-SC),其子代细胞能分化成为神经系统的大部分细胞。以往认为,中枢神经系统的神经元在出生前或出生后不久,就失去再生能力。但近年的一些研究表明,成年哺乳动物的脑组织仍可不断产生新的神经元,成人脑组织中同样存在NSC。
    目前多使用基因转移的方法,建立神经干细胞系,即诱导NSC的细胞周期不断循环往复,从而阻止其分化过程。永生化的NSC具有较好的生物学特性,它们能自我复制并在体外大量增殖,在移植人体内后仍具有多向分化潜能,同时可被转染并稳定地表达外源基因。

    somatic stem cell (成体干细胞)

    正确答案: 是一类成熟较慢但能自我维持增殖的未分化的细胞,这种细胞存在于各种组织的特定位置上,一旦需要,这些细胞便可按发育途径,先进行细胞分裂,然后经过分化产生出另外一群具有有限分裂能力的细胞群。
    成体干细胞的发育等级较低,是多能或单能干细胞。造血干细胞(hematopoietic stem cell,HSC)和骨髓间质干细胞(mesenhymal stem cell)是熟知的成体干细胞。
