Genome wide analysis of gene expression of rat ES cells, rat embryonic fibroblast cells and mouse ES cells

ABSTRACT: Rat ES cells were derived using 3I medium from E4.5 blastocysts. Rat embryonic fibroblast cells were derived form E14.5 embryos. To analyze the mechanism under the selfrenewal of rat ES cells, microarrays were used for the genome wide analysis of gene expressoin profiles in rat ES cells. Rat embryonic fibroblast cells and mouse ES cells were tested at same time as control. Our results from clustering analysis demonstrated that the gene expression profile of rat ES cells resembles mouse ES cells, but not REFs. Keyword: 3I medium; rat embryonic stem cells; mouse ES cells; rat embryonic fibroblast cells Rat ES cells were cultured in 3I medium; rat embryonic fibroblast cells were derived and cultured GMEM/10% FBS; mouse ES cells (C57/BL6)were cultured in GMEM/10% FBS added LIF and feeder cells were removed before RNA extraction. Three replicates each.

Rats have important advantages over mice as an experimental system for physiological and pharmacological investigations. The lack of rat embryonic stem (ES) cells has restricted the availability of transgenic technologies to create genetic models in this species. Here, we show that rat ES cells can be efficiently derived, propagated, and genetically manipulated in the presence of small molecules that specifically inhibit GSK3, MEK, and FGF receptor tyrosine kinases. These rat ES cells express pl  ...[more]
