The Role of Extracellular Vesicles in Osteoporosis: A Scoping Review

As an insidious metabolic bone disease, osteoporosis plagues the world, with high incidence rates. Patients with osteoporosis are prone to falls and becoming disabled, and their cone fractures and hip fractures are very serious, so the diagnosis and treatment of osteoporosis is very urgent. Extracellular vesicles (EVs) are particles secreted from cells to the outside of the cell and they are wrapped in a bilayer of phospholipids. According to the size of the particles, they can be divided into three categories, namely exosomes, microvesicles, and apoptotic bodies. The diameter of exosomes is 30-150 nm, the diameter of microvesicles is 100-1000 nm, and the diameter of apoptotic bodies is about 50-5000 nm. EVs play an important role in various biological process and diseases including osteoporosis. In this review, the role of EVs in osteoporosis is systematically reviewed and some insights for the prevention and treatment of osteoporosis are provided.

Automated summary

Osteoporosis is a common metabolic bone disease characterized by high incidence rates. Extracellular vesicles (EVs) play a significant role in the pathogenesis of osteoporosis, and understanding their role can provide valuable insights for the prevention and treatment of osteoporosis.
