Effect of glucocorticoids on miRNA expression spectrum of rat femoral head microcirculation endothelial cells

The study profiled the differential miRNA expression from femoral head bone microvascular endothelial cells (BMECs) between model group and control group to explore the pathogenesis of steroid-induced osteonecrosis of femoral head (ONFH). Twenty 8-week-old Female Sprague-Dawley (SD) rats were randomly divided into control and model groups. Rats in model group received an intraperitoneal injection of 20-μg/kg lipopolysaccharide (LPS) at an...
