The involvement of collagen in bone biomineralization is commonly admitted, yet its role remains unclear. Here we show that type I collagen in vitro can initiate and orientate the growth of ...

Hydroxyapatite (HA) is a mineral found in human bones and teeth. It plays a role in the structural strength of bone and in bone regeneration.

Level 1 bone consists of bone’s two primary components: chalk-like hydroxyapatite and collagen fibrils, ... as an explanation for bone’s toughness; the crystals are too small to break easily.

Bone is mostly made of mineral crystals and the protein collagen. While the structure of collagen is well understood, how the minerals in bone – made of hydroxyapatite – are organised is less ...

What’s more, hydroxyapatite crystals align along the synthetic fibers much as they do along collagen fibers in natural bone. Molecules with thin hydrophobic tails (left) assemble themselves in ...

The key to this breakthrough is a synthetic yeast nicknamed “osteoyeast.” Inspired by mammalian bone cells called osteoblasts ...

Bone is made primarily of collagen and a crystal mineral called carbonate-substituted hydroxyapatite. About a century ago, scientists discovered that bone is structured like rope, with multiple coils ...

Genetically modified yeast transforms human urine into hydroxyapatite, a valuable biomaterial for bone repair, enhancing ...

Scientists and engineers are eager to understand the secret behind bone’s lightweight toughness so they can mimic it in the design of new materials, but previous studies have revealed a number ...

He found that the mineralized collagen fibrils in level 2 bone are made up of strings of alternating collagen molecules and consistently sized hydroxyapatite crystals.
