In Vitro Assay to Examine Osteoclast Resorptive Activity Under Estrogen Withdrawal

Blog Article

The bone is a highly dynamic organ that undergoes continuous remodeling through an intricate balance of bone formation and degradation.Hyperactivation of the bone-degrading cells, the osteoclasts (OCs), occurs in disease conditions and hormonal changes in females, resulting in osteoporosis, a disease characterized by altered microarchitecture of the bone tissue, ritual sister smoked pineapple and increased bone fragility.Thus, building robust assays to quantify OC resorptive activity to examine galaxy buds skin the molecular mechanisms underlying bone degradation is critical.

Here, we establish an in vitro model to investigate the effect of estrogen withdrawal on OCs derived from the mouse macrophage RAW 264.7 cell line in a bone biomimetic microenvironment.This simple and robust model can also be adapted to examine the effect of drugs and genetic factors influencing OC resorptive activity in addition to being compatible with fluorescent imaging.
