Improper orientation of collagen fibers
Witryna7 kwi 2024 · Osteons are composed of concentric lamellar structure, the concentric lamellae are composed of periodic thin and thick sub-lamellae, and every 5 sub-lamellae is a cycle, the periodic helix angle of mineralized collagen fibers in two adjacent sub-lamellae is 30°. Four biomimetic models with different fiber helix angles were … WitrynaBone cells in the body use proteins in combination with other building blocks to form collagen. Collagen forms fibers, which develop an organic net that a number of minerals, but chiefly calcium and phosphorous, attach themselves to.

WitrynaIt has been known for some time that collagen molecules in the native fibril are axially displaced or staggered by multiples of a unit referred to as D, which has been variously estimated at 64-68 nm. The best value, determined by x-ray diffraction, is now known to be close to 66.8 nm. WitrynaA study by Canty et al. [8] suggests that the orientation of collagen fibrils in the extracellular space is linked to the cytoskeletal organization induced by cellular responses to mechanical stress.
Witryna11 kwi 2024 · The results also confirmed that collagen fiber orientation allows the bone to withstand greater stress without breaking [116,117,118]. Similarly, in the in vitro biomimetic mineralization experiment of collagen, it was also found that the arrangement of collagen fibers had a great influence on the formation and deposition of HA.
