I am looking for cell line/ cell type of mammalian origin, which lacks mitochondria but retains nucleus. I am aware of the cell line which is devoid of mitochondrial DNA called as Rho-zero, however, they are metabolically proficient. The rabbit reticulocyte lysate is one of the options, but those cells are known to lose their mitochondria later in their development, so I am not sure if I should consider that as an option.
Any suggestions?
