We used microarrays to detail the molecular mechanism of cell-death caused by Met deprivation in undifferentiated ES cells and checked the difference of Met cycle relate gene expression between undifferentiated human ES cells and ES cell derived endoderm. Cells were harvested at undifferentiated or differentiated stages for RNA extraction and hybridization on Affymetrix microarrays. We performed gene expression profiles of undifferentiated khES3 cells cultured in complete (compl) or Met-deprived conditions (deltaMet) for 5 or 24 hr.
