[Autoradiography of the exchanges that can occur between murine sarcoma cells (BP 8) and yeast cells (Saccharomyces cerevisiae, complete or protoplast)].

We can tell after observing the resulting negative that yeasts are able, in our experimental conditions, to collect a sequence of ADN and of ARN proceeding from the cancerous cells. Then, those yeasts could turn their synthesis towards the production of new materials. If those informed yeasts were introduced into a mouse, they would induce at the level of the immunocompetent cells a specific immunizing antitumoral power.
