采用小鼠神经母细胞癌细胞无血清培养建立神经细胞老化实验研究模型。
Serum-free culture of mouse neuroblastoma cessl were used for the study of neuronal aging, with microfluorometry of the autofluorescence of lipofuscin as the index of neuronal aging.
过去，Shetty博士以及其他的研究人员认为显示随着大脑的老化，在海马区――学习记忆中心很少有新的神经细胞生成。
Previous studies by Shetty and others had demonstrated that as the brain ages, fewer new nerve cells, or neurons, are born in the hippocampus, the brain's learning and memory center.
评估神经细胞变化的指标检测：采用显微荧光分光光度计测定细胞老化指标脂褐素水平（相对荧光值）反映细胞老化程度；
