Results:(1)NSCs form typical neurospheres under adequate concentration in vitro, which are immunoreactive to Vimentin. Typically and terminally differentiated mature neural cells could not be found without the stimulus of mitogen or only under NSCs self-regulation and self-induction;(2)NSCs derived from hippocampus maintain the character of stem cells much longer with better biological behavior; NSCs passed to the 2-3 passage are the best to graft since they have not differentiated;(3)NSCs cultured in vitro could self-regulate and differentiate into neurospheres and progenitors positively immunoreactive to specific antibodies representing neurons, astrocytes, oligodendrocytes and Schwann cells;(4)There are widespread synaptic contacts between various kinds of descendent clones and cells;(5)Neurospheres could be formed without the stimulus of mitogen when NSCs and OECs are cocultured. Many neurospheres and cells immunoreactive to Vimentin, GFAP, MAP2, 02, p75NGFR, GFAP, S-100, Synaptosis, Vimentin, Tau (Tau is only positive in cocultureof HNSCs+HOECs) could be found;(6)The supernatant fluid triturated from adult rat spinal cord stimulates NSCs to differentiate into neurons, but do not terminally differentiate;(7)Fibroblasts and O4 oligodendrocytes are not supported to grow under this culture medium.Part II: Isolation, culture and identification of rat and human olfactory ensheathing cellsOlfactory ensheathing cells/glials are the most powerful cells to enable the regeneration of axons in the central nervous system.

结果表明：①在适宜的浓度体外培养条件下，NSCs能形成典型的神经干细胞克隆球，Vimentin免疫荧光染色阳性，单靠丝裂原刺激或NSCs自我调节和分化诱导，不会产生典型的终末分化的成熟神经细胞；②海马源性的NSCs维持干细胞特性的时间更长，生物学特性更优；③传至第2～3代的NSCs尚未分化时移植最佳；④体外培养的NSCs能自我调控分化为神经元、星形胶质细胞、O2少突胶质细胞、雪旺氏细胞染色阳性克隆球和前体细胞；⑤各种子代克隆球和细胞存在广泛的突触联系；⑥NSCs与OECs联合培养时，不需丝裂原刺激即能形成克隆球，获得大量Vimentin、GFAP、MAP2、O2、p75NGFR、GFAP、S-100、Synaptosis、Vimentin、Tau(Tau只有人HNSCs+HOECs联合培养时出现阳染)染色阳性的克隆球和细胞；⑦脊髓研磨后的上清液刺激神经干细胞向神经元方向分化，但并不出现终末分化；⑧本研究培养条件不利于成纤维细胞、O4生长。
