Abstract
It is widely believed that evolutionarily advanced cells require nuclei rich in DNA to proliferate, while mitochondria isolated from nuclei cannot proliferate. We have developed a novel stable cell line, designated “mitochondrial cells (MitoCells)”, maintaining active mitochondria, the majority of which lacked nuclei. MitoCells can be continuously generated in culture. Herein, we report proliferation studies of MitoCells. We found that the nuclear DNA-less (nDNA-less) MitoCells, which were sorted with flow cytometry and were filtrated with 1.2 μmeter and 3 μmeter isopore membrane filters, could exist and proliferate. We also confirmed that the sorted nDNA-less MitoCells had mitochondrial DNA(mtDNA) with T9176C mutation analysis and that the unsorted MitoCells had SURF-1 gene of nDNA. These results suggest that MitoCells could have prokaryotic nature with both mtDNA and nDNA.
