Bioceramics Composed of Octacalcium Phosphate Demonstrate Enhanced Biological Behavior [PDF]

, 2016
Bioceramics are used to treat bone defects but in general do not induce formation of new bone, which is essential for regeneration process. Many aspects related to bioceramics synthesis, properties and biological response that are still unknown and ...

Evaluation of bioactivity of octacalcium phosphate using osteoblastic cell aggregates on a spheroid culture device

Regenerative Therapy, 2016
Much attention has been paid to three-dimensional cell culture systems in the field of regenerative medicine, since three-dimensional cellular aggregates, or spheroids, are thought to better mimic the in vivo microenvironments compared to conventional ...

The Solubility of Octacalcium Phosphate at 37°C in the System Ca(OH)2-H 3PO4-KNO3-H2O [PDF]

, 1983
The solubility product of octacalcium phosphate [Ca4H(PO4)3 · 2.5H 2O] has been determined in the system Ca(OH)2-H3PO 4KNO3-H2O at 37°C in experiments involving a range of hydrodynamics, ionic strength, and equilibration time. A value of pK so= 49.3 ± 0.
