| Outline of Final Research Achievements |
We established a culture system to induce primordial germ cell-like cells (cj-PGCLCs) from common marmoset ES cells. The transcriptomic and epigenetic features of cj-PGCLCs were quite similar to those of human PGCLCs. Based on the transcriptome analysis, we identified surface marker antigens that are specifically expressed on cj-PGCLCs. By recognizing these antigens with antibodies, we were able to isolate cj-PGCLCs from a variety of common marmoset ES cell lines. The obtained cj-PGCLCs were differentiated into the late germ cell lineage by co-culture with mouse embryonic ovarian somatic cells, suggesting that they have the ability to differentiate into gametes.
