查询词典 stem cells

BACKGROUND: Bone marrow mesenchymal stem cells of mice are different from human and rats. The difficulties of culture, sustaining impermanency activity of BMSCs after passage and short-term effect of stem cells tracking limited the study of mice.

背景：小鼠骨髓间充质干细胞培养不同于人及大鼠，培养扩展难度高，传代后干细胞活性保持时间短；又鉴于干细胞本身特点，使现有干细胞示踪方法作用时间短，这些因素均影响小鼠骨髓间充质干细胞的实验研究。
