Small RNAs in undifferentiated and differentiating mouse embryonic stem cells
We report the identification of small RNAs in undifferentiated (d0) and differentiating (d4) mouse embryonic stem (ES) cells using high-throughput sequencing.  The goal of this study was to identify small RNAs involved in X-chromosome inactivation (XCI).  We have identified a subset of small RNAs that are generated from transposon sequences and map to the X-chromosome, suggesting their involvement in transposon control on the inactivating X-chromosome. Overall design: Examination of 5 small RNA and 4 RNA-seq libraries in 3 ES cell states.
