Figures 1 and 2 show a Colorswitch experiment in which the
direct influence of HGF on the expression level of liver-specific genes
is analyzed.
To do this, fetal hepatocytes were cultivated under 2 different culture
conditions (collagen 1 without HGF and collagen 1 with HGF, respectively).
The expression of liver-specific markers, such as albumin, Cytochrome
P 450, GST, etc., in the various cultivated hepatocytes was subsequently
tested with the Rat Liver Chip.
The culture condition 2 (collagen 1 with HGF) led to an up-regulation
of liver-specific genes in both experiments.

analysis (Cy3 against Cy5 fluorescence signal, logarithmic) of a typical
experiment according to Figure 1.
The diagonal through the origin represents the anticipated AE of 1.
As a result, HGF leads to an up-regulation of liver-specific genes.
Results
The developed Rat Liver Chip includes 240 liver-specific genes, which
primarily encode phase I and phase II enzymes and matrices. Oxidation,
reduction, methylation and desulphurizing reactions, as well as hydrolytic
cleavages occur in phase I of the
