You have identified a new molecule associated with the immune system that drastically reduces cell division by tumor cells in vivo. Develop a hypothesis and design an experiment to test your hypothesis using a model organism
Include an explanation as to why it is the best model for your experiment.
What will be an ideal response?
Answer: Answers will vary; however, the hypothesis would indicate the utility of the cytokine for lymphoma treatment. The obvious model organism would be the mouse model. It shares a great many similarities to humans at the cellular, anatomical, and physiological levels. It is well characterized, and the genome has been sequenced. Further, there is a mouse model of lymphoma currently available. Mice are easy to care for and require a relatively small amount of space to maintain.
