文题释义:
血管外膜细胞:
是血管周围星状细胞,广泛分布于全身的毛细血管和微血管的管壁,是血管周围微环境的重要核心组成成分。它们可以为其他细胞的生长繁殖提供支持作用以及调节机体的免疫状态和免疫防御等。近年来越来越多的研究显示,血管外膜细胞是间充质干细胞的前体细胞,其表达间充质干细胞表面标记物,具有多向分化潜能,并可支持造血。
造血干细胞:造血干细胞被认为处于造血级联的顶端,具有长期自我更新能力及多向分化潜能,能分化为各种血细胞前体细胞,可以说它是一切血细胞的原始细胞,为机体源源不断提供各种成熟血细胞,同时也能维持自身数量与功能的稳定。

 

摘要
背景:
血管外膜细胞广泛分布于全身的毛细血管和微血管的管壁,是血管周围微环境的重要核心组成成分。它们可以为其他细胞的生长繁殖提供支持作用以及调节机体的免疫状态和免疫防御等。近年来越来越多研究显示,血管外膜细胞是间充质干细胞的前体细胞,其通过细胞接触或旁分泌效应调节造血干细胞的行为并支持造血。
目的:就血管外膜细胞的分布、功能以及对造血干/祖细胞的支持作用作一综述。
方法:以“pericyte,perivascular cell,hematopoietic stem/progenitor cells”以及“血管外膜细胞,间充质干细胞,周细胞,造血干/祖细胞”为检索词,检索PubMed数据库、CNKI数据库及万方数据库2008至2018年间相关文献,并纳入64篇文献进行综述。
结果与结论:血管外膜细胞是间充质干细胞的前体细胞,具有与间充质干细胞相似的生物学特性,表达间充质干细胞的表面标记物,并具有向成骨、成脂及成软骨细胞等分化的潜能,且可调节造血干细胞行为并支持造血。

Abstract:

BACKGROUND: Perivascular cells/pericytes are the important core component of the perivascular microenvironment that are widely distributed throughout the body’s capillary and microvessel wall. These cells can support the growth and reproduction of other cells, and regulate the body’s immune status and immune defenses. In recent years, increasing studies have shown that perivascular cells are the precursor cells of mesenchymal stem/stromal cells, which regulate the behavior of hematopoietic stem cells and support hematopoiesis through cell-to-cell contact or paracrine effects.
OBJECTIVE: To review the distribution and function of perivascular cell/pericytes and their supporting effect on hematopoietic stem/progenitor cells.
METHODS: The key words of “pericyte, perivascular cell, hematopoietic stem/progenitor cells, mesenchymal stem/stromal cells” in Chinese and English were used to retrieve PubMed and CNKI databases for related literature published from 2008 to 2018. Finally, 64 articles were selected to review.
RESULTS AND CONCLUSION: Perivascular cells are the precursor cells of mesenchymal stem cells, which have the similar biological characteristics of mesenchymal stem cells, and express the surface markers of mesenchymal stem cells. In addition, perivascular cells can differentiate into osteoblasts, adipocytes and chondrocytes, regulate hematopoietic stem cell behavior and support hematopoiesis.
