[Effects of fine particulate matter on bone mass and osteogenic differentiation of bone marrow mesenchymal stem cells in mice].

Objective: To observe the effects of exposure to fine particulate matter(PM_(2.5)) on bone mass, microstructure, biomechanical properties, and osteogenic differentiation ability of bone marrow mesenchymal stem cells(BMSCs) in mice.

Methods: A total of 16 C57BL/6J mice aged 8 weeks were randomly divided into control group(NS group) and PM_(2.
