Transcription profiling of mouse developing placenta, with placental and decidual tissues profiled separately

We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). At each stage, the fetal placenta and maternal decidual tissues were dissected and profiled separately Experiment Overall Design: Mouse placentas were obtained from timed pregnant female mice at each timepoint, and fetal tissues were used to confirm embryo staging. Fetal placenta and maternal decidual tissues were dissected and pooled separately for each litter prior to RNA extraction and hybridization on Affymetrix microarrays.
