We have developed a low-cost liver cell culture device that creates fluidic flow over a 3D primary liver cell culture that consists of multiple liver cell types, including hepatocytes and non-parenchymal cells (fibroblasts, stellate cells, and Kupffer cells).

Williams and Kallman pointed out one of the major artifacts in the electron microscopy of biological thin sections, namely, the failure to form images of membranes which are inclined at large angles within the section. This loss is a significant consideration in the qualitative interpretation of electron micrographs and especially in the quantitative assay of endoplasmic reticulum and mitochondrial cristae membranes. In order to estimate the effective loss of membrane images it would be desirable to use a specimen which provides a considerable length of membrane tilted at a known angle and a simple method of measuring its “visibility”. The spherical nuclear envelopes of rat liver parenchymal cells satisfy these conditions. Figure 1 shows part of a binucleate liver cell in which the nuclear membrane is clearly visible around the larger section but blurred by oblique orientation in the smaller section.

Different Origin

In an attempt to establish the functional organization of the hepatic parenchymal unit, we used histo- and microchemical procedures to assess metabolic liver cell heterogeneity at the level of the primary lobule. Because of the close interrelation of glucogenesis and ketone body formation, and in view of the distinct regional differences of the in vivo activity of glucose-6-phosphatase (G6Pase), these techniques were used on livers from male rats to investigate the distribution of the ketogenic enzyme, 3-hydroxybutyrate dehydrogenase (3-HBDH), during the post-resorptive phase. A close reciprocity was found between the general increase in the activity of 3-HBDH and the decrease of the in vivo activity of G6Pase along the sinusoidal axis, and also with regard to enzyme gradients along sinusoids of different origin. The activity of the ketogenic enzyme was higher throughout septal than portal sinusoids, whereas the opposite applied to the glucogenic enzyme. Histo- and microchemical data support the concept of a lobular parenchymal unit composed of "primary lobules," and show also that hepatocyte function varies with cell location along the sinusoidal axis and with the origin of the sinusoids.

Parenchymal Cells

Liver parenchymal cells show a wide variety of plasma membrane transporters that are tightly regulated by endocrine and nutritional factors. This review summarizes work performed in our laboratory on these transport systems, particularly nucleoside transporters, which are up-regulated in physiological situations associated with liver cell growth. Rat hepatocytes show a Na+-dependent nucleoside transport activity that is stimulated by pancreatic hormones. Indeed, this biological activity appears to be the result of the co-expression of at least two isoforms of nucleoside carriers, CNT1 and CNT2 (also called SPNT). These two transporters are up-regulated during the early phase of liver growth after partial hepatectomy, although to different extents, suggesting differential regulation of the two isoforms. The recent generation of isoform-specific antibodies allowed us to demonstrate that carrier expression may also have complex post-transcriptional regulation on the basis of the lack of correspondence between mRNA and protein levels. The analysis of nucleoside transport systems in hepatoma cells and the comparison with those in hepatocytes has also provided evidence that the differentiation status of liver parenchymal cells may determine the pattern of nucleoside transporters expressed.Key words: liver, hepatocyte, regeneration, cell cycle, nucleoside, plasma membrane, transport systems.
