Mouse Global gene expression profiles of mouse embryonic day3.75 inner cell mass cells


ABSTRACT: The goal of this study is elucidating the mechanisms of the primitive endoderm (PrE, founder of the yolk sac) segregates from the epiblast (EPI, founder of the foetus). Within the uterus and ex vivo, precursors of the EPI and PrE emerge in an unsorted manner in inner cell mass (ICM). Coincident with identity acquisition, the cells physically sort, resulting in PrE establishing a single layer of cells covering the cavity-facing surface of the ICM with the EPI enclosed between the PrE and polar trophectoderm. The mechanism that determines this spatial segregation between EPI and PrE is still poorly understood. To achieve this goal, we have compared mouse embryonic day (E) 3.75 ICM cells’ transcriptome profiling to other existing mouse E3.5 and E4.5 ICM cells’ RNA-seq data. We have identified the timing of EPI and PrE lineages specification and maturation and each stage- and lineage-specific genes expression profiles.
