根据美国国立老年研究所(NIA)的报告,骨质疏松症的研究策略侧重于下面五个方面: 1、骨质丢失的基础生物学研究探索从分子和细胞的水平上来阐明骨质丢失的机制。骨的重建和吸收依赖于破骨细胞,骨的新生和置换依赖于成骨细胞,这两类细胞现已明确均来源于骨髓。它们的发 According to the report of the National Institute of Aging (NIA), the research strategy for osteoporosis focuses on the following five aspects: 1. The basic biological study of bone loss explores mechanisms of bone loss at the molecular and cellular levels . Bone remodeling and uptake is dependent on osteoclasts, and bone regeneration and replacement depend on osteoblasts, both of which are now clearly bone marrow-derived. Their hair
