Does calcium activate osteoblasts?
Calcium supports PTH effects on osteoblast proliferation and bone formation.
What is bone matrix?
Bone matrix is a composite material that derives its strength from a compression-resistant mineral phase and a tension-resistant network of collagen fibers.
What is involved in bone resorption?
Bone Resorption: Osteoclast Action and Proteolytic Enzymes. Bone resorption involves both dissolution of bone mineral and degradation of organic bone matrix. Osteoclasts are highly specialized to perform both of these functions.
How can I improve my osteoblast activity?
Additional components known to enhance osteoblast differentiation are strontium, isoflavones, and whey protein [40–42]. Whether any of these dietary components actually leads to an increase in the anabolic response of bone tissue—as a whole—to mechanical loading remains to be investigated.
What hormone stimulates osteoblast activity?
Thyroxine, a hormone secreted by the thyroid gland promotes osteoblastic activity and the synthesis of bone matrix.
What affects osteoblast activity?
OPG expression in osteoblasts is regulated by amount of hormones, cytokines and growth factors (Theoleyre et al., 2004), such as estrogen, 1, 25(OH)2D3 and TNF. RANKL is also called osteoclast differentiation factor (ODF), TNF-related activation-induced cytokine (TRANCE) and osteoprotegerin ligland(OPGL)(Lacey et al.
What hormone is responsible for stimulating bone resorption?
Parathyroid hormone (PTH)
Parathyroid hormone (PTH) stimulates osteoclast proliferation and resorption of bone by osteoclasts.
What is responsible for replacing bone matrix?
osteoblasts
While bone resorption is performed by large immune cells called osteoclasts, osteoblasts, a type of specialized connective tissue-related cells, is responsible for making new bone. Bone remodeling is impaired in osteopetrosis due to inadequate osteoclast function and impairment of bone resorption.
What happens when there is abnormal bone resorption?
Conditions that result in a decrease in bone mass can either be caused by an increase in resorption or by a decrease in ossification. During childhood, bone formation exceeds resorption. As the aging process occurs, resorption exceeds formation….

Why does an endocrinologist treat osteoporosis?
Since osteoporosis can develop without any obvious symptoms, it is up to endocrinologists to spot often overlooked signs of bone loss and conduct research to improve understanding of osteoporosis and other bone diseases.
How long does it take for bone to remodel?
About 20% of all bone tissue is replaced annually by the remodeling process. There are five phases in the bone remodeling process: ACTIVATION, RESORPTION, REVERSAL, FORMATION, and QUIESCENCE. The total process takes about 4 to 8 months, and occurs continually throughout our lives.
How does osteoporosis affect the bone matrix?
With osteoporosis, there is reduced bone density and structure in the spongy bone, as well as thinning of the cortical bone. When your bones have thinned to the point that osteoporosis is diagnosed, the physical structure — and soundness — of your bones has changed.
