Table 1. Mean percentage of distinct leukocyte populations positive for different leukocyte markers in unstimulated perfused trout liver in comparison to spleen and kidney (N = 6).

Populations	Liver	Spleen	Kidney
IgM+	13.70±8.20	28.64±14.66	14.45±2.93
IgD+	2.83±1.60	3.86±1.95	2.67±1.96
MHC-II+	23.30±6.30	72.30±5.65	63.47±14.12
CD8α+	3.91±1.02	4.34±0.59	3.37±1.15
Thrombocytes+	0.85±0.40	5.84±4.54	0.80±0.29

The percentages were calculated over the leukocyte gate.
