简介:目的体外模拟机体缺血环境,研究骨髓间充质干细胞(MSCs)旁分泌对心脏成纤维细胞胶原合成的影响,为MSCs移植机制提供实验依据.方法分离培养SD大鼠的MSCs,换以无血清培养液同时缺氧处理不同时间,然后收集MSCs的条件培养液,以此条件培养液作为刺激因子孵育SD大鼠的心脏成纤维细胞,用MTT和3H-脯氨酸掺入观察心脏成纤维细胞的增殖及胶原合成.结果用MSCs条件培养液培养心脏成纤维细胞,3H-脯氨酸掺入明显高于对照组,缺氧6h组的3H-脯氨酸掺入高于对照组约100%,提示MSCs条件培养液刺激心脏成纤维细胞胶原合成增加;MTT结果无显著差异,提示:MSCs条件培养液没有影响心脏成纤维细胞的增殖.结论大鼠骨髓间充质干细胞的缺氧和无血清条件培养液能够通过旁分泌刺激心脏成纤维细胞自身合成胶原能力的增强,提示移植到缺血心肌缺血区的骨髓间充质干细胞可能通过旁分泌作用影响心脏成纤维细胞的胶原合成,从而参与损伤心肌的修复.

简介:债权得以实现主要依靠债务人自觉履行债务的行为,如果债务人不积极履行债务,债权人虽诉诸法律程序也往往难以收到实效。有时法院判决由债务人清偿债务,但因判决时债务人已丧失了清偿能力,或因第三人对债权有异议,或债务人虽对第三人享有债权,但通过执行第三人的途径仍然保证不了债权的实现等。律师执业过程中遇到此类情况应当尽其可能为债权人谋求一些诉讼或仲裁以外的解决纠纷的方法,使债权人免遭经济损失。经济纠纷是纷繁复杂的。债务人在对债权人负有债务的同时常常对第三人享有债权;第三人在对前还债务人负有债务的同时也可能对前述债权人中享有债权。债务人对债权人负债、债权人对第三人负债、第三人对债务人负债的事实使债务人、第三
