Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

科学领域:

  • 整形生物学 (OBs) 涵盖了一系列针对骨科疾病的再生医学疗法.

背景情况:

  • 基于血液 (例如,富血小板血 - PRP) 和基于组织/细胞 (例如,介质细胞 stromal 细胞) 的疗法越来越多地被使用.
  • 准备和试验质量的异质性使OB的基于证据的指导方针变得复杂,特别是在诸如膝关节骨关节炎等疾病中对PRP的疗效.

研究的目的:

  • 审查当前的骨科生物疗法格局和制定基于证据的临床指导方针的挑战.
  • 为突出需要标准化协议和改善的临床试验框架为orthobiologics.

主要方法:

  • 对基于血液和基于细胞/组织的骨髓生理学药物的现有元分析和随机对照试验 (RCT) 的审查.
  • 分析骨科学会 (例如,ESSKA,AAOS) 制定指南的努力.

主要成果:

  • 在特定的骨科条件下,PRP显示出改善患者结果的潜力,但RCT通常具有很高的偏差.
  • 基于细胞/组织的疗法有较长的发展管道;虽然安全,但证据不如PRP那么丰富,主要集中在膝关节关节炎上.
  • 骨科协会正在使用综合证据和专家共识制定指南.

结论:

  • 准备,应用和结果测量的标准化协议对于脊椎生物学至关重要.
  • 患者分层和强大的临床试验框架对于释放整形生物学药物的全部潜力和建立可靠的指南至关重要.
