Long-term cell-mediated protein release from calcium phosphate ceramics.
Efficient delivery of growth factors from carrier biomaterials depends critically on the release kinetics of the proteins that constitute the carrier. Immobilizing growth factors to calcium phosphate ceramics has been attempted by direct adsorption and usually resulted in a rapid and passive release of the superficially adherent proteins. The insufficient retention of growth factors limited the...
متن کاملAddition of Alumina to Nanoporous Calcium Titanium Phosphate Glass-Ceramics and its Effects on Crystallization Behavior
Microporous Calcium Titanium Phosphate glass-ceramics have many uses in high-tech industries. For example, they have applications in catalysts industry. In this study, different molar percentages of alumina were added to a glass with P2O5 30, CaO 45, TiO2 25 (mol%) composition. The samples were melted at 1350°C and crystallization heat treatment was performed on...
متن کاملBone regeneration: molecular and cellular interactions with calcium phosphate ceramics
Calcium phosphate bioceramics are widely used in orthopedic and dental applications and porous scaffolds made of them are serious candidates in the field of bone tissue engineering. They have superior properties for the stimulation of bone formation and bone bonding, both related to the specific interactions of their surface with the extracellular fluids and cells, ie, ionic exchanges, superfic...
متن کاملSynthetic calcium phosphate ceramics for treatment of bone fractures.
Bone is a complex natural material with outstanding mechanical properties and remarkable self-healing capabilities. The mechanical strength is achieved by a complex structure of a mineral part comprising apatitic calcium phosphate crystals embedded in an organic matrix. Bone also contains several types of cells constantly replacing mature bone with new bone. These cells are able to seal fractur...
متن کاملThe material and biological characteristics of osteoinductive calcium phosphate ceramics
The discovery of osteoinductivity of calcium phosphate (Ca-P) ceramics has set an enduring paradigm of conferring biological regenerative activity to materials with carefully designed structural characteristics. The unique phase composition and porous structural features of osteoinductive Ca-P ceramics allow it to interact with signaling molecules and extracellular matrices in the host system, ...
