Atom RSS Feed Bone is a mineralized connective tissue from which bones, the main component of the vertebrate skeleton, are formed. Bone tissue is composed of cells, namely osteoblasts, osteoclasts and osteocytes, and an extracellular matrix comprising inorganic hydroxyapatite crystals and organic collag...
Successful materials design for bone-tissue engineering requires an understanding of the composition and structure of native bone tissue, as well as appropriate selection of biomimetic natural or tunable synthetic materials (biomaterials), such as polymers, bioceramics, metals and composites. Scalable fabri...
Bone - Structure, Function, Types: Grossly, bone tissue is organized into a variety of shapes and configurations adapted to the function of each bone: broad, flat plates, such as the scapula, serve as anchors for large muscle masses, while hollow, thick-

Bones can be classified by their shape and their macroscopic/microscopic structure. The basic unit of bone is the mineralized collagen...
Role of ferroptosis in lumbar disc herniation. Normal intervertebral discs consist of the external annulus fibrosus (AF), which forms a ring structure surrounding the nucleus pulposus (NP). Intervertebral disc degeneration, which is affected by various factors, is the primary cause of lumbar disc he...
Bone is a connective tissue composed of an organic collagenous matrix, a fine dispersion of reinforcing inorganic (calcium phosphate) nanocrystals, and bone-forming and -degrading cells. These different components have a synergistic and hierarchical structure that renders bone tissue properties unique in...
Cortical bone is made of osseous tissue, a type of connective tissue specific to bones. Osseous tissue consists of osteocytes, or bone cells, surrounded by a solid intercellular matrix of mineral salts and protein fibers. The matrix of osseous tissue is particularly rich in the calcium- and ph...

In addition, biomaterials carrying cells can be transplanted into the injured region. Transplanted cells can repair damaged nerves by promoting axonal regeneration, remyelinate denuded axons, ...
A honeycomb structure in a hydrogel was created with 3D bioprinting to simulate the vasculature in vitro for evaluating the migration of cancer cells, which showed that a reduced width of bioprinted capillaries increased the migratory velocity of cancer cells.126 In addition to the vessel diameter,...
The periosteum is a layer of dense connective tissue covering the surface of bone. It is tightly attached at the bone end and where the tendon is connected. Elsewhere, it is thick and easy to peel off. Although the tissue structure of the periosteum varies with different anatomical sites an...
