WebMar 29, 2013 · Osteoclasts, the bone-resorbing cells, play a pivotal role in skeletal development and adult bone remodeling. They also participate in the pathogenesis of various bone disorders. Osteoclasts ... WebTwo main types of cells are responsible for bone metabolism: osteoblasts (which secrete new bone), and osteoclasts (which break bone down). The structure of bones as well as adequate supply of calcium requires close cooperation between these two cell types and other cell populations present at the bone remodeling sites (e.g. immune cells).

WebApr 14, 2024 · Osteoporosis is a disease that is characterised by reduced bone mineral density (BMD) and can be exacerbated by the excessive bone resorption of osteoclasts (OCs). Bioinformatic methods, including functional enrichment and network analysis, can provide information about the underlying molecular mechanisms that participate in the … WebNov 10, 1998 · Generally, it has been assumed that bone formation and bone resorption functions are linked mechanistically during bone remodeling (BR; refs. 2 – 4 ). One implication of this model is that the absence of or a functional defect in one cell type would greatly decrease the function of the other cell type to maintain a constant bone mass.
