概括
炎症和缺血性心力衰竭与减少喷射率 (HFrEF) 显著增加心血管死亡风险. 中酶体前体细胞 (MPCs) 在高风险的炎症HFrEF患者中大大减少了主要的不良心血管事件.
科学领域:
- 心脏病学 心脏病学
- 再生医学是一种再生医学.
- 免疫学 免疫学 免疫学
背景情况:
- 减少喷射分数 (HFrEF) 的心力衰竭涉及促炎和修复性心脏巨细胞之间的不平衡.
- 介质细胞前体细胞 (MPCs) 显示出恢复这种平衡并改善炎症条件下的结果的潜力.
研究的目的:
- 在DREAM-HF试验中确定HFrEF患者心血管死亡 (CVD) 风险因素.

Mesenchymal Stem Cells
4.6K
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...
