Abstract
Background
Osteonecrosis of femoral head (ONFH) is a pathological state caused by lack of blood
supply in femoral head. This study aimed to explore the function of Lycium barbarum
polysaccharide (LBP), an antioxidant agent extracted from L. barbarum, on ONFH.
Methods
Osteonecrosis rat model was generated using lipopolysaccharide (LPS) and methylprednisolone
followed by examination of body weight, blood glucose, morphology, and BMSC osteoblast
differentiation. The effect and underlying mechanism of LBP on the proliferation,
apoptosis, and osteoblast differentiation of BMSC were determined with or without
LPS or hypoxia treatment using CCK-8. Alizarin Red S staining, flow cytometry, and
western blot, respectively.
Result
LBP could protect against glucocorticoid-induced ONFH in rats, resulting in improved
sparse trabecular bone, empty lacunae and bone cell coagulation. Moreover, LBP promoted
the proliferation and osteoblast differentiation of bone mesenchymal-derived stem
cells (BMSCs) in a dose-dependent manner. Furthermore, LBP enhanced osteoblast differentiation
of BMSCs under hypoxia condition. Mechanistically, we found that LBP treatment enhanced
Runx2 and ALP expression in BMSCs. LBP restored the expression of Runx2 and ALP under
hypoxia, suggesting that LBP might be involved in regulating Runx2/ALP expression
and contributed to osteoblast differentiation. Knockdown of Runx2 significantly inhibited
BMSCs proliferation, while LBP treatment did not rescue the osteoblast differentiation
ability of BMSCs with Runx2 knockdown.
Conclusion
Our findings suggested that LBP protects against ONFH via regulating Runx2 expression,
which could be utilized to treat patients suffering ONFH.
