     With regard to the structure of protoplasm, he held that it was vesicular, the reticulum or walls of the vesicles being the part of the protoplasm in which the plasmogen resides, which is not contained in vesicular spaces.

   • 1912, Hugh S. Elliot, “Modern Vitalism”, in Bedrock, volume 1, page 328:

     With further cooling, and under certain physical conditions, with which we are unacquainted, combinations of yet greater complexity began to appear in special association with carbon, till at length the proteins and plasmogen were reached; and the peculiar physical and chemical properties of these complex substances are what we now call vital.

   • 1913, Edwin Ray Lankester, Science from an Easy Chair, page 191:

     To construct plasmogen itself is a task for the chemists of the distant future.

2. Misspelling of plasminogen.

     After binding to fibrin of blood clot, the plasmogen activator causes plasmin to accumulate in the vicinity of the clot.

   • 2021, Louis Dechmann, Valere Aude: Dare To Be Healthy:

     The administrations of N. sativa essential oil (25-200μg oil/mL( resulted in a substantial downregulation of the particular fibrinolytic product which included the plasmogen activator (t-PA), plasmogen activator inhibitor type 1 (PAI-1), and urokinase type plasmogen activator (u-PA) in cell cultures.
