Bone tissue collagen maturity

WebAug 4, 2024 · Bone tissue is a two-component material made primarily of poorly crystalline hydroxyapatite tablets and type I collagen-based organic matrices . The mineral component confers stiffness to the bone tissue (2, 3) while collagen confers a degree of tensile strength, ductility, and toughness (4, 5). WebDec 14, 2011 · In inner bone, mineral maturity was reduced compared to the center bone, both in control and lathyritic bones (1.28 vs 1.20, respectively), and collagen maturity decreased in parallel (2.4 in both control and lathyritic bones). Thus for a given mineral maturity, collagen maturity did not vary between control or lathyritic bones .
