在这份报纸，我们报导人的脐的绳索的生存能力的辨别有导致相片的推迟的光(DL ) 的间充质的干细胞(hUC-MSCs ) 。我们用一个 ultraweak 光察觉系统测量 hUC-MSCs 的 DL 腐烂动力学，并且与高、低的生存能力为 hUC-MSCs 在腐烂率的重量分布发现重要差别。光谱有高、低的生存能力的 hUC-MSCs 的辨别被比较 DL 动力学参数因此执行包括起始的紧张，山峰腐烂率和山峰重量珍视。我们的结果证明为 hUC-MSCs 的生存能力诊断的新奇光方法有有希望的前景。

英文摘要：

In this paper, we report the discrimination of the viability of human umbilical cord mesenchymal~ stem cells （hUC-MSCs） with photo-induced delayed luminescence （DL）. We measure the DL decay kinetics of hUC-MSCs using an ultraweak luminescence detection system, and find the significant difference in the weight distributions of the decay rate for hUC-MSCs with high and low viabilities. Spectral discrimination of hUC-MSCs with high and low viabilities is thus carried out by comparing the DL kinetics parameters, including the initial intensity, the peak decay rate and the peak weight value. Our results show that the novel optical method for the viability diagnosis of hUC-MSCs has a promising prospect.
