Conditioned media to inhibit growth of tumor cells

摘要

Conditioned media compositions having valuable biological activity are obtained from cultures of immune cells from elasmobranch fishes. A method is provided for producing the conditioned media compositions. Conditioned media obtained using epigonal cells from bonnethead sharks (Sphyrna tiburo) and lemon sharks (Negaprion brevirostris) demonstrate strong anti-tumor activities. The conditioned media compositions can be used for treating tumor proliferation.
