Outline of Final Research Achievements |
The objective of this study was to establish feline ES (embryonic stem) cell lines and iPS (induced pluripotent stem) cell lines, and to induce hematopoietic cells from these stem cells. The following results were obtained. ① Blastocyst formation was observed using piezo-ICSI, and primary feline ES-like cell conolies were formed from blastocysts. ② We confirm the successful production for the first time of biologically active feline LIF within E.coli.③ We transduced four transcriptional factors (mouse Oct3/4, Sox2, Klf4, c-Myc) into fetal fibroblast cells of domestic cats with retrovirus vector, and could establish an iPSC-like cell line.④ We transduced four transcriptional factors into fetal fibroblast cells of domestic cats with sendai virus vector, and primary feline iPS-like cell colonies were formed.⑤ Feline iPS-like cells can be differentiated into macrophages and erythroid cells.
