( D ) Survival of BALB/c cardiac allografts in B6 and cDC1-KO mice as determined by manual palpation with rejection occurring at complete cessation of heartbeat and a palpation score of 0. n = 9–11 per group. **** P < 0.0001 by log-rank test. ( E ) Mean palpation score of BALB/c cardiac allografts in B6 and cDC1-KO mice. ( F ) Measurement of fractional shortening of cardiac allografts by echocardiography 42 days after transplantation. n = 3 per group. * P < 0.05 by 2-tailed unpaired t test.
