What bone cells are responsible for the deposition of minerals?
Osteocytes, the living cells of bone tissue, form the mineral matrix of bones. There are two types of bone tissue: compact and spongy.
What is responsible for bone deposition in the body?
Bone is resorbed by osteoclasts, and is deposited by osteoblasts in a process called ossification. Osteocyte activity plays a key role in this process.
What are osteocytes osteoblasts and osteoclasts?
Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells. An equilibrium between osteoblasts and osteoclasts maintains bone tissue.
What are osteoblasts?
Osteoblasts are specialized mesenchymal cells that synthesize bone matrix and coordinate the mineralization of the skeleton. These cells work in harmony with osteoclasts, which resorb bone, in a continuous cycle that occurs throughout life.
What do osteocytes do?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
What are osteoclast cells?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/monocyte lineage that circulate in the blood after their formation in the bone marrow.
What osteocytes do?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
What are osteoblasts and osteocytes?
Cells that are involved in growing bone: Osteoblasts, lining the surface of bone, secrete collagen and the organic matrix of bone (osteoid), which becomes calcified soon after it has been deposited. As they become trapped in the organic matrix, they become osteocytes. Osteocytes maintain bone tissue.
What do osteoblast cells do?
Osteoblasts are specialized mesenchymal cells that synthesize bone matrix and coordinate the mineralization of the skeleton. These cells work in harmony with osteoclasts, which resorb bone, in a continuous cycle that occurs throughout life.
What is osteoblast and osteoclast?
Osteoblast and osteoclast are the two main cells participating in those progresses (Matsuo and Irie, 2008). Osteoclasts are responsible for aged bone resorption and osteoblasts are responsible for new bone formation (Matsuoka et al., 2014). The resorption and formation is in stable at physiological conditions.
What do osteocytes cells do?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.

What is osteocyte and osteoblast?
Osteocytes are derived from osteoblasts and make up over ninety percent of the cells in bone. However, the mechanisms that control the differentiation of osteoblasts into osteocytes embedded in bone matrix are not well understood.
Are osteocytes osteoblasts or osteoclasts?
These cells also control the differentiation and activity of osteoclasts. Osteocytes are osteoblasts that have been incorporated into bone matrix and are cells with extensive dendritic processes through which the cells communicate with other osteocytes and with osteoblasts.
