    GO:2000352    negative regulation of endothelial cell apoptotic process    Any process that stops, prevents or reduces the frequency, rate or extent of endothelial cell apoptotic process.
    GO:1902042    negative regulation of extrinsic apoptotic signaling pathway via death domain receptors    Any process that stops, prevents or reduces the frequency, rate or extent of extrinsic apoptotic signaling pathway via death domain receptors.
    GO:0051918    negative regulation of fibrinolysis    Any process that stops, prevents, or reduces the frequency, rate or extent of fibrinolysis, an ongoing process that solubilizes fibrin, resulting in the removal of small blood clots.
    GO:0010466    negative regulation of peptidase activity    Any process that stops or reduces the rate of peptidase activity, the hydrolysis of peptide bonds within proteins.
    GO:0010757    negative regulation of plasminogen activation    Any process that decreases the rate, frequency or extent of plasminogen activation. Plasminogen activation is the process in which plasminogen is processed to plasmin.

    GO:2000098    negative regulation of smooth muscle cell-matrix adhesion    Any process that stops, prevents, or reduces the frequency, rate or extent of smooth muscle cell-matrix adhesion.
    GO:0061044    negative regulation of vascular wound healing    Any process that decreases the rate, frequency, or extent of blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels and contribute to the series of events that restore integrity to damaged vasculature.
    GO:0061045    negative regulation of wound healing    Any process that decreases the rate, frequency, or extent of the series of events that restore integrity to a damaged tissue, following an injury.
    GO:0002576    platelet degranulation    The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.
    GO:0045766    positive regulation of angiogenesis    Any process that activates or increases angiogenesis.
