Figure 1. Rejection of primary and secondary allogeneic skin grafts in μMT B6 mice.
Comparison of the number of days until rejection of primary sensitizing skin grafts versus rejection of secondary skin grafts. μMT B6 (n = 11–13) mice were skin grafted with fully MHC-mismatched B10.A tail skin and followed daily for rejection. Ten weeks following rejection of the first graft, the mice were then regrafted and followed daily for second-set responses. The skin graft data from two separate experiments were compiled and subjected to T-test (**p < 0.005).
