Fluorescence microscopy of mitochondria after SCNT. Fluorescence microscopy of donor cell preloaded with CMXRos, 30Â min after fusion of donor cell into enucleated oocyte. Donor-derived mitochondria locate near the donor nucleus and disperse into the cytoplasm in developing embryos with heteroplasmy as observed up to the blastocyst stages. From Zhong et al. [4].
