| Popis: | We manufactured a highly sensitive oligonucleotide microarray system comprised entirely of transcription regulatory factors (a TF oligo microarray) in order to comprehensively analyze the expression profiles of transcription factors in mice. We compared the expression profiles of transcription regulatory factors in mouse embryonic stem (ES) cells and ES-differentiated cells by using this TF oligo microarray, a cDNA microarray, a GeneChip system, and quantitative RT-PCR. The TF oligo microarray was able to comprehensively analyze the expression profile of transcription regulatory factors. In addition, we used the manufactured TF oligo microarray to analyze the expression patterns of transcriptional regulatory factors during the formation of embryoid bodies. The TF array was able to reveal the chronologic expression profile of transcription regulatory factors involved in embryogenesis or the maintenance of pluripotency in ES cells. |
