During mouse development, the implanting blastocyst embryo is composed of the inner cell mass (ICM) and the outer trophectoderm (TE) layer. Permanent stem cell lines can be derived from these two lineages; embryonic stem (ES) cells from ICM [1] [2] and trophoblast stem (TS) cells from TE [3]. TS cells can differentiate into multiple cell types only of the trophoblast lineage, while ES cells can differentiated into all three germ layer cell types. TS cells grow in the presence of fibroblast growth factor (FGF) 4 and mouse embryonic fibroblast-conditioned medium (MEF-CM). Removal of FGF4 and MEF-CM from the TS cell culture medium causes them to differentiate in vitro into trophoblast giant cells and other trophoblast subtypes. We want to investigate how gene expression is controlled in the trophoblast lineage. To do this we conducted a timecourse analysis of gene expression profiles of TS cells after the removal of FGF4 and MEF-CM. |

|
TS cell lines are maintained in an undifferentiated state in the presence of FGF4 and 70% MEF-CM, and are differentiated by removal of FGF4 and MEF-CM for 0, 1, 2, 3, 4, 5, or 6 days (total 7 points). We used following three TS cell lines: a wild-type female TS cell line “B1”, a wild-type male TS cell line “Rybp”, and an Ring1A-/- male TS cell line “R1AB” (Ring1A-/- mice are healthy and exhibit no apparent phenotype in placental tissues [4]) . |
