The tissue was chopped into a fine paste, resuspended in DMEM + L-Glut, Pen-Strep and 20% FBS, and plated out in a 25cm flask. In general, the following sites should be avoided: The known biology and effects of any individual tumor model must be described in the animal use protocol, including expected clinical signs, anticipated moribundity/mortality, interventions for the relief of pain and suffering, and objective criteria for the assessment of humane endpoints. A tumour that spreads to the blood and lymphatic system can travel to the skin. .
