PLoS Comput Biol:计算机模拟间充质干细胞疗法 将心脏病治疗风险降至很低

2016-07-27 佚名 生物谷

最近科学家们使用数学计算模型模拟了人类间充质干细胞到达心脏损伤部位的过程,发现只用一个特定亚群的干细胞就能最大限度地减少间充质干细胞疗法带来的相关风险。相关研究结果发表在国际学术期刊Plos Computational Biology上,该研究代表了心肌损伤修复和再生策略的新发展,能够提高干细胞疗法在心脏病患者中的应用安全性。心肌梗死——也即心脏病发作——在美国平均每43秒就会发生。这一情况大大激

最近科学家们使用数学计算模型模拟了人类间充质干细胞到达心脏损伤部位的过程,发现只用一个特定亚群的干细胞就能最大限度地减少间充质干细胞疗法带来的相关风险。相关研究结果发表在国际学术期刊Plos Computational Biology上,该研究代表了心肌损伤修复和再生策略的新发展,能够提高干细胞疗法在心脏病患者中的应用安全性。

心肌梗死——也即心脏病发作——在美国平均每43秒就会发生。这一情况大大激励了科学家们对心肌损伤修复和再生治疗新方法的开发,其中包括人类间充质干细胞治疗。但是在临床试验中间充质干细胞疗法的作用常常比较微弱且短暂,这表明我们对于间充质干细胞如何影响心脏功能的机制仍了解有限。

美国西奈山伊坎医学院的Joshua Mayourian等人使用数学计算模型模拟了这些干细胞与心脏细胞之间的电相互作用,深入了解了其中可能存在的有害影响,同时提出了降低间充质干细胞治疗中一些潜在风险的可能方法。

他们的计算机模拟结果表明一个人类间充质干细胞亚群能够将干细胞对单个心肌细胞和整个组织电活性的干扰降至最小,这群特定的间充质干细胞亚群或可增加心脏病患者接受干细胞治疗的安全性。该研究因此有望引领新的临床研究,并在未来改进对心衰病人的干细胞治疗。

这项研究开发了一个新的数学计算模型未来可用于对间充质干细胞进行计算研究。该研究还为人类间充质干细胞和心脏细胞之间的相互作用提出了新的见解,可以指导未来的实验性研究,进一步理解间充质干细胞用于心脏病治疗的机制.
