褪黑素在制备预防间充质干细胞早衰药物中的应用
摘要：
本发明提供褪黑素在制备预防间充质干细胞早衰药物中的应用，所述间充质干细胞为骨髓间充质干细胞，从人源、猪源、鼠源或兔源组织获取，用CCK-8检测褪黑素对早衰间充质干细胞增殖能力的影响，用SA-β-Gal染色检测分析褪黑素作用于早衰间充质干细胞后SA-β-Gal染色阳性率的变化，用流式细胞术检测分析褪黑素作用于早衰间充质干细胞后细胞周期的变化，用钙结节茜素红染色，钙结节定量检测分析褪黑素对早衰间充质干细胞成骨分化能力的影响。本发明为以间充质干细胞为基础的细胞疗法防御氧化应激损伤提供了一种策略。
摘要（英）：

The invention provides application of melatonin in preparation of a medicine for preventing premature senility of mesenchymal stem cells; the mesenchymal stem cells are mesenchymal stem cells obtained from human, pig, mouse or rabbit tissues; influence of the melatonin to the multiplication capacity of premature senility mesenchymal stem cells is detected by using CCK-8; change of the SA-beta-Gal dyeing positive rate after the melatonin acts on the premature senility mesenchymal stem cells is detected and analyzed by using SA-beta-Gal dyeing; change of the cell cycle after the melatonin acts on the premature senility mesenchymal stem cells is detected and analyzed by using a flow cytometry; dyeing is carried out by using calcium nodule alizarin red; and influence of the melatonin to the osteogenesis ability of the premature senility mesenchymal stem cells is quantitatively detected and analyzed by using calcium nodule. Application disclosed by the invention provides a policy for preventing oxidative stress injury through cell therapy based on the mesenchymal stem cells.
