Summary
Understanding physiological mineralization, initiated by matrix vesicles, offers insights into preventing pathological soft tissue mineralization. This review explores key regulators and mechanisms for therapeutic development.
Area of Science:
- Biomineralization
- Cell Biology
- Tissue Engineering
Background:
- Physiological mineralization is crucial for skeletal health.
- Pathological mineralization in soft tissues causes significant morbidity and mortality.
- Mechanisms of physiological and ectopic mineralization may overlap.
Purpose of the Study:
- To review current knowledge on physiological mineralization mechanisms.
- To identify determinants regulating physiological mineralization.
- To explore how these determinants can inform strategies against ectopic mineralization.
Main Methods:
- Literature review of recent findings on mineralization.
- Analysis of matrix vesicle function.
- Examination of mineralization regulators (activators and inhibitors).
Main Results:
- Matrix vesicles initiate both physiological and pathological mineralization.
- Identified activators and inhibitors regulate both processes.
- Apoptosis may contribute to physiological and induce ectopic mineralization.
Conclusions:
- Understanding physiological mineralization mechanisms is key to preventing ectopic mineralization.
- Matrix vesicles and regulatory factors offer therapeutic targets.
- Apoptosis's role in mineralization warrants further investigation.

01:40Bone Remodeling
40.1K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:31Essential Minerals for Bone Health
5.8K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:18The Bone Matrix
5.3K
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

01:29Bone Disorders
5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:31Osteoclasts in Bone Remodeling
3.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

01:17Hormones and Bone Tissue
3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
