Experimental mouse. Gloved hand holding a nude breed of mouse,Mus muscula,which has been specially bred for use in medical experiments. This mouse does not have a functioning thymus gland,meaning that some of the cells in its immune system cannot mature. These T cells would normally attack foreign tissue and regulate the activity of other types of immune cells. Due to its deficiency,this mouse can have samples of cancer-causing chemicals (carcinogens),human tumours or skin tissues transplanted into its body. The development of any cancers,and the effect of drugs upon them,can then be observed | |
