| Research Abstract |
1) Cloning of Azoospermy factor gene (AZF)
We found YAC in which AZF should be included and subcloned the cosmid contig mede from the YAC to a plasmid vector. AZF was included within 30 Kb DNA.Then, using Exon trapping we picked up severalfunctional exons from each cosmid. After all of sequences were analyzed using the DNA data base in the Gene Bank, not a few exons revealed unknown sequences. Screening using the testis cDNA libraryis is now on in progree.
2) Cloning of genes which induce differentiation of human testis germ cells
For molecular cloning of genes which induce differentiation of human testis germ cells we screened human testis cDNA library using mouse cDNAs as probes. We isolated human SCP-1 which appears in the phase before the miosis and determined sequences of the DNA and the protein.
3) Establishment of in vitro culture of human germ cells
We established in vitro culture system of human germ cells which has been very difficult. Using this system we will be able to do experiments in vitro differentiation human germ cells.
