They may constitute a model for problems of cellular recognition and differentiation, since they may acquire and lose membrane markers during differentiation (Boyce and Ol

Whether or not the rodents are the proper objects of such immunological anthropomorphism can be argued, but it is clear that a concentration on the immune system of a few

The hypothesis that transplants are destroyed by an immunological reaction is based upon Medawar’s demonstration of specific accelerated rejection of repeat tissue grafts derived from the original donors, i.e., the second-set phenomenon (Medawar, 1963). Allografting thus causes the host
