Fig 8. Apoptotic cell density increases with increasing harvest time.

Quantitative analysis of the density of apoptotic cells in lymph nodes subject to (A) 1-hour, (B) 2-hours, (C) 4-hours, and (D) 8-hours of ischemia. There is a trend of increasing apoptotic cell density as harvest time increases. Analysis was completed in three random high-powered fields per lymph node. Data are presented as mean ± S.E.M. N = 16 lymph nodes per group. *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001.
