For the extensive use of precision-cut liver slices (particularly of human origin) for toxicological investigations successful cryopreservation is necessary. But so far, survival of thawed slices was limited to few hours. This was now overcome by modification of previous procedures. The concentration of DMSO as a cryoprotectant was enhanced to 30%, and washing steps after rapid thawing were omitted. The slices were frozen in liquid nitrogen, thawed at 38 degrees C and incubated immediately in Williams medium E. Protein and potassium contents were stable until 24 h. Glutathione content, amounting to nearly 50% of fresh slices, increased during incubation. High initial lactate dehydrogenase leakage dropped after medium change to less than half during 2-24 h. Testosterone hydroxylation and 7-ethoxycoumarin O-deethylation rates were similar to fresh slices, the latter reaction was inducible by beta-naphthoflavone within 24 h. Methylumbelliferone glucuronidation and p-nitrophenol glucuronidation and sulfation were well measurable and either maintained or decreased by about 50% until 24 h.Altogether, the results are encouraging for further experiments to standardise cryopreservation conditions and to investigate the suitability of this cryopreservation protocol with human liver slices.
