Abstract
The immunogenic activity of native and irradiated syngeneic and xenogeneic tumor cells, carrying a common transplantation antigen specific for SV40 on their surface, was compared in Syrian hamsters. The results showed that syngeneic tumor cells were more immunogenic for the recipient than xenogeneic tumor cells containing antigen of the same specificity. Irradiation makes tumor cells, including xenogeneic cells, more immunogenic, possibly on account of the ability of the unirradiated cells to escape recognition on account of their ability to divide.
