Description générale

Hydroxyapatite(HAP) is an osteoconductive bioceramic material which has uniqueability to form direct bonds with living tissues. It can be easily prepared byvarious techniques such as sol-gel, hydrothermal, multiple emulsion, biomimeticdeposition, and electrodeposition.

Application

Hydroxyapatite can be used as:
  • An implant material for bone substitute due to its chemical similarity to the inorganic component of bone and osteo inductive properties.
  • A vehicle for gene and drug delivery because of its encapsulation capacity and affinity to several drugs and proteins.
  • A pH responsive particulate emulsifier.

Caractéristiques et avantages

  • Biocompatible
  • Osteoconductive
  • Stable under physiological conditions
  • High mechanical strength

The scavenger receptor cysteine-rich (SRCR) family of proteins comprises more than 20 membrane-associated and secreted molecules. Characterised by the presence of one or more copies of the ∼110 amino-acid SRCR domain, this class of proteins have widespread functions as antimicrobial

Calcium phosphate precipitates (CPPs) form complexes with DNA, which enter cells via endocytosis. Under this condition CPPs induce autophagy via the canonic autophagy machinery. Here we showed that CPP-induced autophagy was also dependent on endocytosis as the process was significantly

Pyrophosphate ions are both inhibitors of HA formation and substrates for phosphatase enzymes. Unlike polyphosphates their hydrolysis results simultaneously in the complete loss of mineral formation inhibition and a localised elevation in orthophosphate ion concentration.

Recombinant human bone morphogenetic protein-2 (rhBMP-2) applied on an absorbable collagen sponge improves open tibial fracture-healing as an adjunct to unreamed intramedullary nail fixation. We evaluated rhBMP-2 and a new, injectable calcium phosphate matrix (CPM) formulation in acute closed tibial

As an alternative to an autologous bone graft, deproteinized bovine bone (DBB) is widely used in the clinical dentistry. Although DBB provides an osteoconductive scaffold, it is not capable of enhancing bone regeneration because it is not osteoinductive. In order
