Abstract
The menopausal hormone abnormal changes such as estrogen deficiency and increased FSH secretion in female patients in old age may cause osteoporosis which is plagued by patients. The pathogenesis of osteoporosis is not yet fully understood. BMP in the transforming growth factor-β
superfamily is a key member in the process of bone growth and development, among which BMP-2 exerts critical roles. Impaired osteogenic differentiation of bone marrow mesenchymal stem cells (BMSC) contributes to the progress of osteoporosis. BMSC plays an indispensable role in treating osteoporosis
and can develop into different directions through induction. As the regenerative medicine nanotechnology has become a new medical method, it is believed that BMSC can be used to treat osteoporosis and other related diseases. Our study analyzed the effects of BMP-2/estrogen composite nanoparticles
on the proliferation and differentiation of osteoporotic BMSC cells to provide a reliable reference for the future treatment. Our results showed that BMP-2/estrogen composite nanoparticles promoted BMSC cell proliferation, increased ALP activity, decreased apoptosis rate, increased the expression
of Col-1, Runx2 and Osterix, upregulated the osteogenic marker BMP-2. As confirmed by Alizarin Red staining, it could differentiate into osteoblasts and the content of Trap was decreased. In conclusion, our study confirms that BMP-2/estrogen composite nanoparticles can promote BMSC cell proliferation,
osteogenic differentiation, and inhibit osteoclast differentiation, thereby providing new treatments and theoretical reference basis for treating osteoporosis.
