Conditioned medium (CM) from cultured NOV/COS-7 cells (NOV-CM) was collected, it markedly promoted the incorporation of JH-TdR in cultured NSCs, the effect was concentration-dependent, this indicated that NOV-CM promoted proliferation of NSCs.

• 收集培养NOV/COS、7细胞的条件培养液（NO－CM），发现NOV－CM能明显促进 NSCSsH1dR的摄入，且其作用存在一定的量效关系，提示NOVCM能刺激NSCS的增殖；
