摘要 随着年龄的增长,大脑侧脑室的室下带及海马齿状回产生新的神经能力却在下降,其机制现在不是很清楚,可能是与成人大脑老化过程中内部的一些改变有关。成人大脑与婴幼儿大脑相比,其神经发生的能力显著下降,而老化的大脑内部结构功能的改变及有害产物增加、信号转导通路异常等一系列的内环境的改变都抑制了神经的发生,退行性疾病则更加剧了这种抑制效应,这也致使神经干细胞移植在治疗神经退行性疾病的应用中受到限制。在神经干细胞移植治疗取得成功之前,必须清楚认识成人大脑、老化大脑和退行性病变的大脑内部的一系列变化过程及其对神经干细胞的影响作用,鉴于这一点,本文将着重介绍近几年对成人大脑及病变大脑内神经干细胞生物学特性的最新研究成果,和神经干细胞对神经退行性疾病的治疗进展。
