Rat hepatocytes prepared without collagenase: Prolonged retention of differentiated characteristics in culture

  • Published:
Cell Biology and Toxicology Aims and scope Submit manuscript

Rat hepatocytes prepared by collagenase digestion or ED TA dissociation were examined in culture for comparison of culture stability and morphology, and retention of selected adult rat liver characteristics. Cells prepared by EDTA perfusion followed by Percoll cen trifugation were deemed to form confluent monolayer cultures more rapidly and monolayers remained intact for up to 21 days without signs of nonparenchymal cell growth or loss of primary hepatocyte appearance. The spectrally determined cytochrome P-450 content remained constant through eight days in culture. Collagenase prepared cells contained an identical amount of P-450 but within 72 hr lost greater than 80% of the spectrally detectable P-450. Glutathione (GSH) content was higher in the EDTA-prepared hepatocytes and remained constant with only a modest effect of transferrin and selenium (TI S) supplementation, while GSH levels in collagenaseprepared cells increased, thereafter decreased with time in culture and was dependent on TI S supplementation. Cells prepared with ED TA also displayed an increase in GSH efflux rate in response to chronic GSH depletion by ethacrynic acid. γ-Cystathionase (CNase) activity was retained at initial levels in ED TAprepared hepatocytes supplemented with TI S and declined only about 25% in unsupplemented cells. Collagenase-prepared cells lost 75% of CNase activity by 72 hr. The established marker of hepatocyte neoplastic transformation, γ-glutamyl trans-peptidase (GGT), increased rapidly in collagenase-prepared cells. The accumulation of GGT was slowed by T/S supplementation. GGT activity did not increase in EDTA-prepared hepatocytes. Evaluation of morphological and biochemical criteria suggest that hepatocytes prepared without collagenase present superior model systems for the study of biochemical events through more extended culture times.
