mtDNA copy number of 143B osteosarcoma following EtBr exposure.

Cell type	Days without EtBr	mtDNA (copy/cell)
143B	—	1060.11
𝜌^08w	0	0.93
𝜌^08w revertant	14	1009.9
Clone #23	50	0.98

143B: parental osteosarcoma; 𝜌⁰8w: 143B following 8 weeks of EtBr exposure; 𝜌⁰8w revertant: recovered mtDNA level in the absence of EtBr for 14 days.
Clones 23, 24, 31, 35, 36, and 38 were selected clones through limiting dilution.
