The Bone Matrix01:18

The Bone Matrix

3.0K
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...

Bone Remodeling01:40

Bone Remodeling

38.2K
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.

Main Methods:

  • Literature review focusing on calcium phosphates in in vitro bone model development.
  • Analysis of CaP's properties influencing cell proliferation, differentiation, and matrix formation.
  • Evaluation of CaP's suitability for osteogenesis, angiogenesis, and mechanical support.

Main Results:

  • Calcium phosphates exhibit properties essential for mimicking bone physiology in vitro.
  • CaP materials promote osteogenesis and angiogenesis, crucial for bone tissue generation.
  • The physico-chemical characteristics of CaP provide mechanical integrity for bone models.

Conclusions:

  • Calcium phosphates are indispensable for developing functional in vitro bone models.
