| Outline of Final Research Achievements |
The aim of this project is the establishment of transgenic reptiles as a new experimental model of life sciences. To achieve this purpose, we targeted adult testicular stem cells and introduced expression vectors for fluorescent proteins (a linearized RFP expression vector and GFP expression vector with transposon sequences) into the testis of adult Madagascar ground geckoes. At 10 days after in vivo electroporation, we confirmed RFP and GFP expression in the testicular cells in seminiferous tubes. Furthermore, we detected RFP transgene in 1 of 8 embryos by genomic PCR analysis. These data suggest that making transgenic reptiles by targeting adult testicular stem cells is highly feasible, although further technical improvements are required to increase the efficiency of transgenesis.
