Mechanisms of calcification: role of collagen, polyphosphates, and phosphatase

Fleish, Herbert, Neuman, William F.·1961·American Journal of Physiology-Legacy Content

Abstract

The nucleating properties of various collagens have been tested by determining quantitatively the minimum ion product, Ca times P, required to form calcium phosphate crystals. While most collagens require a product of 35 (mg%) 2 or greater for calcium phosphate to precipitate, some collagens extracted from tendon induce mineralization at a product of 16 (mg%) 2 . Plasma ultrafiltrate contains one or more substances which increase this minimum ion product, and therefore inhibit calcium phosphate nucleation. These substances are inactivated by alkaline phosphatase. Finally, polyphosphates, both organic and inorganic, are highly inhibitory to calcium phosphate nucleation and precipitation. It is therefore suggested that at least two mechanisms may be necessary for a tissue to mineralize: 1) the formation of a nucleating collagen and 2) the presence of phosphatase for the local destruction of the inhibitor(s) present in plasma.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
