title: Inhibition of Crotalidae venom hemorrhagic activities by Didelphis marsupialis liver spheroids culture supernatants.
abstract: The main aim of this work was the development of a primary hepatocyte culture from Didelphis marsupialis, to determine the possible use of culture medium supernatants as a source of inhibitors of the Bothrops lanceolatus venom hemorrhagic activity. The cellular culture was carried out from isolated hepatocytes by the double perfusion technique, and digestion of the liver with collagenase and culturing the hepatocytes in a liquid media under continuous agitation at 37 degrees C in 5% CO2. The hemorrhagic activity inhibition assays were performed inoculating intradermically, a mixture of Bothrops lanceolatus venom plus a pool of liver spheroids culture supernatants, in mice. These liver Didelphis marsupialis spheroid cultures were adequate to obtain large supernatant volumes with inhibitors of hemorrhagic activity.
