Outline of Final Research Achievements |
Primordial germ cells (PGCs) are origin of all germ cell lineage including sperm and egg. During embryogenesis PGCs are specified at an early developmental stage. This study aims to identify genes involved in PGC specification by using haploid embryonic stem cell lines, which are convenient for forward genetics to identify functional genes. Thus far, we have constructed a plasmid vector that interfere endogenous gene expression at the integrated genomic locus. By transfection of the plasmid vector to haploid ES cells, we have made a pool of ES cell lines in which multiple copies of the vectors are inserted in the genome. Based on the established materials, we are going to screen functional genes involved in PGC specification.
