Bone marrow adipose tissue (BMAT), sometimes referred to as marrow adipose tissue (MAT), is a type of fat deposit in bone marrow. It increases in states of low bone density, such as osteoporosis , [ 1 ] [ 2 ] anorexia nervosa / caloric restriction , [ 3 ] [ 4 ] skeletal unweighting such as that which occurs in space travel , [ 5 ] [ 6 ] and ...
Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly . [ 3 ]
Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
4. Are some women more at risk for osteoporosis? Yes. Your risk for osteoporosis is higher if you: Are past menopause. After menopause, your ovaries make very little of the hormone estrogen.
The bone disease osteoporosis, which significantly increases the risk of fracture, is a serious health concern. As we age, the prevalence of osteoporosis increases—especially for women.
A typical fat cell is 0.1 mm in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
Calcification is synonymous with the formation of calcium-based salts and crystals within cells and tissue. It is a process that occurs during ossification, but not necessarily vice versa. The exact mechanisms by which bone development is triggered remains unclear, but growth factors and cytokines appear to play a role.
