Modified Cells (IMAGE) Cell Press Caption This image shows human osteosarcoma cells and mitochondria (green), with additional mitochondria (red) from human embryonic kidney cells transferred via the nanoblade. Very few red-labeled mitochondria are actually delivered by the nanoblade into each cell, compared to the pre-existing green mitochondria. Over a few weeks, the mitochondrial DNA in the red-labeled mitochondria will massively amplify. Credit Ting-Hsiang Wu Usage Restrictions Credit Required.
