| Outline of Final Research Achievements |
Primordial germ cells, the origin of germline cells, undergo epigenetic reprogramming in which their epigenetic modifications dramatically change just after their specification in mice. To elucidate the molecular basis of it, the roles of three transcription factors, BLIMP1, PRDM14, and TFPA2C were analyzed on a genome-wide scale. By utilizing an in vitro culture system that is functionally validated, ChIP-seq (chromatin immunoprecipitation followed by high-throughput DNA sequencing) and transcriptome analyses were conducted. These analyses suggested that both of BLIMP1 and PRDM14 played a pivotal role in the activation of germline program, and TFAP2C contributed to activation of transcription.
