Fig 12. With an ischemic period of 4 hours, average percentage of apoptotic leukocytes increases with longer harvest time.

Quantitative analysis of: (A) apoptotic cell density in tissue subject to 4 hours of ischemia; (B) percentage of apoptotic T cells in tissue subject to 4 hours of ischemia; (C) percentage of apoptotic leukocytes in tissue subject to 4 hours of ischemia. Analysis was completed in three random high-powered fields per lymph node. Data are presented as mean ± S.E.M. N = 4 lymph nodes per group. *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001.
