Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

5.0K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

科学领域:

  • 免疫学
  • 复原医学
  • 传染性疾病

背景情况:

  • 细菌感染导致全球数百万人死亡,而抗菌药物耐药性使治疗复杂化.
  • 介质干细胞/流体细胞 (MSC) 和它们的分泌物正在作为细菌感染的新疗法进行探索.
  • 由于MSC的定义和特征不一致,现有关于细菌感染的MSC的临床前研究显示出变异性.

研究的目的:

  • 在动物模型中系统审查使用人类MSC及其分泌物治疗细菌感染的研究.
  • 提供证据概述,以指导未来的MSC治疗细菌感染的临床研究.

主要方法:

  • 在PROSPERO注册的系统审查中,遵守PRISMA指南.
  • 在PubMed中搜索了介质干细胞,细菌感染和治疗的术语.
  • 从包含的研究中使用叙事方法合成数据.

主要成果:

  • 三十七项研究符合纳入标准,分析了动物模型中的人类MSC和分泌物效应.
  • 人类MSC减少了细菌负载,减少了伤害,改善了生存率,骨髓衍生MSC是最有效的.
  • 在动物中,MSC及其分泌物表现出免疫调节能力.

结论:

  • 在临床前的细菌感染中,基于干细胞和无细胞的MSC疗法显著有前途.
  • 局限性包括依赖动物模型和缺乏供体特异性数据,阻碍临床转化.
  • 在临床实施之前,MSC异质性仍然是一个挑战,需要进一步研究.
