Abstract: A cell culture system includes a first component having an opening at the bottom, a membrane for diffusing a gas into a liquid by dissolution, an enclosure able to hold a volume of gas that can diffuse into the liquid via the membrane and a drive member for driving the container, the container being inclined at a non-zero angle ? that is less than or equal to 30°. A cell culture system comprising a first component and a second component forming a ring-shaped container and a drive member, the container being inclined at a non-zero angle ? that is less than or equal to 30°. A method using a system of the invention and to an assembly comprising a system of the invention and a liquid containing a species that is to be cultured.

Abstract: A pharmaceutical composition intended for use in the prevention and/or treatment of leukaemia in a subject, the composition includes palytoxin (PLTX) and a pharmaceutically acceptable carrier. The application also relates to other medical uses of palytoxin and a method for its extraction from Palythoa clavata polyps. A method for isolating the symbiodinium dinoflagellate from Palythoa clavata is also described.
