背景情况:
- 母亲的免疫耐受性对于成功怀孕至关重要.
- 果性介质干细胞 (MSCs) 在调节母体免疫反应方面发挥作用.
- 了解MSC在自发性流产 (SA) 和复发性流产 (RA) 中的功能至关重要.
研究的目的:
- 评估人类叶MSCs对淋巴细胞增殖,细胞亡和调节性T细胞 (Treg) 百分比在第一季度堕胎中的免疫活动.
- 将这些MSC活动与自发性流产 (SA) 和复发性流产 (RA) 进行比较.
主要方法:
- 一个前性队列研究,对在第一季度堕胎的妇女进行.
- 从SA和RA病例 (SA-MSC和RA-MSC) 中分离和分类数叶性MSC.
- 与SA-MSCs和RA-MSCs共同培养周围血液单核细胞,以评估对淋巴细胞增殖,亡和Treg水平的影响.
主要成果:
- 与对照组相比,MSC显著增加了Treg百分比,同时降低了淋巴细胞增殖和亡.
- 在RA-MSCs与SA-MSCs相比,Treg百分比的增加和亡的减少显著减少.
- 虽然MSCs的增殖抑制作用在RA-MSC中较低,但这种差异在统计学上并不显著.
结论:

Mesenchymal Stem Cells
4.7K
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...

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...
