[The effect of pH, temperature and albumin content on the vitality of fetal rat liver cells during in vitro tests].

The influence of pH, temperature, and albumin content in the incubation medium on the vitality incubated hepatocytes was tested in vitro as well as the effects in the trypan-blue exclusion test. pH changes between 6.8 and 7.4 in the incubation medium have not any influence on the vitality of the hepatocytes or the trypan-blue exclusion test. Reduced vitality results occurred in an initial pH 7.8 in the incubation medium. The vital dye exclusion test is not useful in case of incubation temperature of 4 degrees C, since the results regarding the vitality of the hepatocytes are only apparently better. An addition of human serum albumin is necessary for a good survival of the hepatocytes during the incubation.
