概括
与安慰剂相比,膝关节骨关节炎的干细胞注射可能会略有改善疼痛和功能,但证据质量较低. 长期益处,对生活质量的影响和安全性仍然不确定.
科学领域:
- 再生医学是一种再生医学.
- 整形外科 整形外科 整形外科
- 生物技术是生物技术.
背景情况:
- 干细胞是能够修复组织的专门细胞,越来越多地用于膝关节骨关节炎 (OA).
- 干细胞治疗膝关节OA的确切机制,益处和危害尚未完全理解.
- 现有证据需要综合来指导临床实践和患者决策.
研究的目的:
- 评估干细胞注射治疗膝关节关节炎的益处和危害.
- 通过活跃的系统审查,保持最新的证据基础.
主要方法:
- 在多个数据库 (CENTRAL,MEDLINE,Embase) 和临床试验注册表中进行系统搜索.
- 包括随机对照试验 (RCT) 和准随机试验,将干细胞注射与各种对照试验进行比较 (安慰剂,没有治疗,其他注射等). ) 的情况.
- 使用GRADE方法进行数据提取,偏差风险评估和证据确定性评估.
主要成果:
- 包括25个RCT (1341名参与者),大多数试验规模小,容易产生偏见.
- 与安慰剂相比,干细胞注射在疼痛和功能改善方面显示出低确定性益处,长达六个月.
- 关于生活质量,治疗成功和严重不良事件的证据的确定性非常低,表明存在重大不确定性.
结论:
- 根据低确定性证据,干细胞注射对膝盖OA患者的疼痛和功能提供了潜在的,尽管很小的改善,而不是安慰剂.
- 关于对生活质量的影响,治疗成功率以及膝关节OA干细胞治疗的整体安全性概况,仍然存在重大不确定性.
- 对再生效应和结构变化的潜力仍未得到证实,需要进一步进行高质量的研究.

Stem Cell Therapy for Tissue Regeneration
4.0K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

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...
