| Outline of Final Research Achievements |
In order to establish chicken-mutant library, we tried to culture chicken primordial germ cells using STO cells expressing chicken LIF as feeder cells. By using this feeder cells, certain level of PGC-growth and expression of PGC-marker was observed but reproducibility was very low. Then, we analyzed a key regulator gene that governs and sustains PGC-differentiation and growth, in order to facilitate the PGC-culture experiments. We chose prdm 14 as a candidate, and cloned the gene. By the functional analyses, we found that prdm 14 up-regulated PGC-specific gene expression.
