Transcriptional profiling of stem cells. Embryonic, neural, and hematopoietic stem cells, as well as the corresponding differentiated cell populations (lateral ventricle brain and bone marrow main population), were isolated and their mRNAs were amplified and hybridized to oligonucleotide arrays. The arrays were analyzed by a combination of the Microarray Suite (Affymetrix) and dChip (Wong lab, Harvard) software, followed by public database searches and functional annotation. Indicated at the bottom are well-known genes that were expected to be enriched in each of the three stem cells and were indeed detected as enriched.
