During embryonic development of some organisms including mice and humans, certain genes will exhibit genomic imprinting: cells will express only the copy of the gene expressed from one parent, either the mother or the father. In the study that produced this image, researchers analyzed the overall tissue-specific gene expression of a maternally-expressed imprinted gene, Zim1, during mouse embryo development. The nucleus of each cell is labeled with blue dye, and cells expressing the gene are also labeled with red dye.
