TL;DR
A pattern of Set 1-related transcripts very similar to that observed in midgestation embryos is found in pluripotential EC and EK cell lines, and the abundance of these RNAs decreases upon differentiation in vitro.
Abstract
We have previously isolated cDNA clones homologous to mRNAs present at elevated levels in transformed mouse fibroblasts. Clones of Set 1 contain a dispersed repetitive element present thousands of times in the mouse genome. This repeat identifies in mouse embryos a large number of transcripts that are quantitatively regulated during development. At maximal expression these RNAs constitute between 1% and 3% of polyadenylated RNA. A pattern of Set 1-related transcripts very similar to that observed in midgestation embryos is found in pluripotential EC and EK cell lines, and the abundance of these RNAs decreases upon differentiation in vitro. However, the F9 line of EC cells, which has a more restricted developmental capacity, exhibits a much simpler pattern of transcripts containing the Set 1 repeat.

The cell type generated by retinoic acid and dibutyryl cAMP treatment is therefore indistinguishable from definitive parietal endoderm, and analysis of the final phenotype indicates that it is not dependent upon the continued presence of either compound, and that cAMP agents are active only on cells that have been treated with retinoi acid.
