| Outline of Final Research Achievements |
In this study, we tried to establish the functional new cell lines (iPS cell lines and immortalized cell line) from critically endangered animals. We used the sea turtles, and lowland anoa, and african savanna elephant. The primary cells shows enlarged cytoplasm after the specific times of cell divisions. In these cell lines, senescence associated protein, p16 is expected to accumulated in its cytoplasm. In general, senescence cells shows positive staining for SA-beta galactosidase staining.
For the induction of immortalized cell lines, the genetic introduction by lentiviruses were used. The primary cells of the critically endangered animals were immortalized with the expression of mutant cyclin dependent kinase (CDK4) and Cyclin D, and enzymatic subunit of human derived telomerase.
