Abstract

A protein that stimulates the production of plasminogen activator and latent collagenase in cultured bovine capillary endothelial cells has been purified 10(6)-fold from term human placenta by using a combination of heparin affinity chromatography, ion-exchange chromatography, and gel chromatography. The purified molecule has a molecular weight of 18,700 as determined by NaDodSO4/PAGE under both reducing and nonreducing conditions. The purified molecule stimulates the production of plasminogen activator and latent collagenase in a dose-dependent manner between 0.1 and 10 ng of protein/ml. The purified protein also stimulates DNA synthesis and chemotaxis in capillary endothelial cells in the same concentration range. Thus, this molecule has all of the properties predicted for an angiogenic factor.

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.
