Trypan blue-assessed cell viability before cryopreservation and after thawing of primary hepatocytes from cattle and pig.

Species	Trypan blue-negative hepatocytes per total cell fraction (%)
	Before	After	Difference
Cattle	87 ± 7	50 ± 17*	−36 ± 19
Pig	87 ± 3	63 ± 13*,#	−24 ± 13#

Data are means ± SD (n = 96 using 6 animals for each species) with p < 0.001 vs. ^*before of the same species and ^#cattle of the same test group (two-way ANOVA with Bonferroni post-hoc test).
