The transcriptional profiles of mouse embryonic, neural, and hematopoietic stem cells were
compared to define a genetic program for stem cells. A total of 216 genes are enriched in all
three types of stem cells, and several of these genes are clustered in the genome. When
compared to differentiated cell types, stem cells express a significantly higher number of
genes (represented by expressed sequence tags) whose functions are unknown. Embryonic
and neural stem cells have many similarities at the transcriptional level. These results …
