New method of studying the release of fibrinolysis activators in tissue cultures

Tissue cultivation in the presence of standardized fibrin clot containing plasminogen permitted to reveal and to study quantitatively the relase of the fibrinolysis activators into the medium (by the amount of the fibrin-fibrinogen degradation products). A possibility of in vitro study of the regulation of fibrinolysis activators release by the tissues was offered by the method described.
