Individual weight-gain records of a litter of 6 newborn C57BL/6 mice all of which received an intra- venous injection of 12 million DBA/i spleen cells at birth. On the fifth day of life four animals (solid dots) received a second intravenous injection of 18 million spleen cells from adult C57BL/6 mice which had pre- viously rejected skin grafts from DBA/i donors. This is a particularly favourable example of the protective effect which can be achieved by a relatively late injection of sensitized cells. within a single litter and may be attributable in part to differences in the immunological capacity of the cells used in different experi- ments. Microscopic examination of the spleens and lymph nodes of surviving animals treated in this way at about 4 weeks of age reveals considerable hyperplasia with many active germinal centres.
