The proliferating AR42J-B13 pancreatic cell line is known to respond to glucocorticoid treatment by producing foci of cells that express the liver-specific albumin gene. We demonstrate that this cell line also expresses liver-specific or liver-enriched functional cytochrome P450 proteins when stimulated to trans-differentiate into hepatocytes by glucocorticoid. These data suggest that this cell line has an unusual ability to trans-differentiate into functional hepatocytes and that it could be possible to generate a limitless supply of functional hepatocyte-like cells in vitro.

The rat pancreatic progenitor cell line B-13 is of interest for research on drug metabolism and toxicity since the cells trans-differentiate into functional hepatocyte-like cells (B-13/H) when treated with glucocorticoids.

The R28 rat retinal progenitor cell line was developed from postnatal day six rat retina immortalized with the 12S E1A gene of adenovirus. R28 cells have been distributed to over 100 laboratories worldwide, with over 60 publications on topics that include in vitro toxicology, cellular physiology, gene expression analysis, and experimental transplantation. In this paper, we present a microarray dataset of R28 cells that describes the presence or absence of 8799 genes and ESTs that may be relevant to current and future studies of R28 retinal precursor cells.

Abstract We show a dramatic downregulation of the stem cell factor (SCF) receptor in different hematopoietic cell lines by murine stroma. Growth of the human erythroid/macrophage progenitor cell line TF-1 is dependent on granulocyte-macrophage colony-stimulating factor (GM-CSF) or interleukin-3 (IL-3). However, TF-1 cells clone and proliferate equally well on stroma. Independent stroma-dependent TF-1 clones (TF-1S) were generated on MS-5 stroma. Growth of TF-1S and TF-1 cells on stroma still requires interaction between c-kit (SCF receptor) and its ligand SCF, because antibodies against c-kit inhibit growth to less than 2%. Surprisingly, c-kit receptor expression (RNA and protein) was downregulated by 2 to 3 orders of magnitude in TF-1S and TF-1 cells grown on stroma. This stroma-dependent regulation of the kit receptor in TF-1 was also observed on exposure to kit ligand-negative stroma, thus indicating the need for heterologous receptor ligand interaction. Removal of stroma induced upregulation by 2 to 4 orders of magnitude. Downregulation and upregulation of c-kit expression could also be shown for the megakaryocytic progenitor cell line M-07e and was comparable to that of TF-1, indicating that stroma-dependent regulation of c-kit is a general mechanism. Downregulation may be an economic way to compensate for the increased sensitivity of the c-kit/ligand interaction on stroma. The stroma-dependent c-kit regulation most likely occurs at the transcriptional level, because mechanisms, such as splicing, attenuation, differential promoter usage, or mRNA stability, could be excluded.
