Osteoblasts

Meaning

Osteoblasts are specialized, mononuclear cells responsible for the synthesis and mineralization of the bone matrix, the organic and inorganic components that give bone its strength and structure. These cells are essential for bone formation, a continuous process known as bone remodeling, which maintains skeletal integrity throughout life. They play a critical role in calcium homeostasis and are directly influenced by a range of systemic hormones, including parathyroid hormone, calcitonin, and sex steroids. A healthy population and activity of osteoblasts are paramount for preventing osteoporosis and maintaining musculoskeletal health.
