Genomic and proteomic characterization of embryonic stem cells.

Stem cell biology, like all areas of cell biology, has been significantly affected by the arrival of the genomics era. The rendering of the human and mouse genome sequences and the development of attendant technologies have made it possible to comprehensively explore embryonic stem cell biology at the molecular level. Recently, there has been emphasis on global characterization of the transcriptome, epigenome, and proteome of embryonic stem cells. These omic evaluations of embryonic stem cells are leading to improved methods for cell-based therapies and are advancing our basic understanding of early embryonic development.
