Figure 2.
Characterization of HHT3 and HHT4 cells. (A) Representative phase-contrast cell image (a) and electron micrographs (b, c) of HHT4 cells are shown. Representative images of a mitotic HHT3 cell (d-f) and a mitotic HHT4 cell (g-i) analyzed by fluorescence in situ hybridization (FISH) with a whole chromosome 16 painting probe or whole chromosome 1 painting probe, respectively. (B) Expression profiles of hepatocyte-specific genes in HHT3 and HHT4 cells analyzed by cDNA microarray. The expression ratios of HHT3 or HHT4 cells over hTERT-immortalized normal human fibroblasts (NHF) are shown. Hepatocyte-specific genes were selected based on a SAGE transcript profile of freshly isolated and cultured normal primary human hepatocytes (33).
