   *these mineralo-organic nanoparticles form spontaneously in body fluids when the concentrations of calcium and phosphate ions exceed saturation, although it may be that they develop from **membrane vesicles (MVs)** secreted by various cells.   *these mineralo-organic nanoparticles form spontaneously in body fluids when the concentrations of calcium and phosphate ions exceed saturation, although it may be that they develop from **membrane vesicles (MVs)** secreted by various cells.
     *these MVs are 20-400nm in size and contain the serum proteins albumin, fetuin-A, and apolipoprotein A1; the mineralization-associated enzyme alkaline phosphatase; and the exosome proteins TNFR1 and CD63, and have been shown to form nanoparticles when added to cell culture medium and that it may be the presence of calcium-binding lipid phosphatidylserine (PS) on their surface which acts as nucleating sites for calcium phosphate deposition on the vesicles. **This would suggest that secretion of MVs are the cause of the calcification, and not nanoparticles per se** (([[http://www.ncbi.nlm.nih.gov/pubmed/23990473]]))     *these MVs are 20-400nm in size and contain the serum proteins albumin, fetuin-A, and apolipoprotein A1; the mineralization-associated enzyme alkaline phosphatase; and the exosome proteins TNFR1 and CD63, and have been shown to form nanoparticles when added to cell culture medium and that it may be the presence of calcium-binding lipid phosphatidylserine (PS) on their surface which acts as nucleating sites for calcium phosphate deposition on the vesicles. **This would suggest that secretion of MVs are the cause of the calcification, and not nanoparticles per se** (([[http://www.ncbi.nlm.nih.gov/pubmed/23990473]]))
