High-throughput screen for genes predominantly expressed in the ICM of mouse blastocysts by whole mount in situ hybridiz


ABSTRACT: We attempted to identify candidate genes that are expressed more highly in the ICM than in TE cells. Mouse ES cells are cultured from the ICM, whereas mouse TS cells are cultured from the TE. Although these cells have been cultured in vitro, they represent the in vitro equivalents of the ICM and TE. Therefore, genes which are expressed more highly in ES than TS in microarray studies were good candidates for genes predominantly expressed in the ICM in blastocysts.

Mammalian preimplantation embryos provide an excellent opportunity to study temporal and spatial gene expression in whole mount in situ hybridization (WISH). However, large-scale studies are made difficult by the size of the embryos ( approximately 60mum diameter) and their fragility. We have developed a chamber system that allows parallel processing of embryos without the aid of a microscope. We first selected 91 candidate genes that were transcription factors highly expressed in blastocysts, a  ...[more]
