Porter/SPL Scientists have extracted mitochondria from a woman’s leg muscles and injected them into the vitreous fluid of her eyes in an attempt to treat severe
Labelling the cellular structures with ECL probes Preparation of Ru(bpy)3 2+–N-hydroxysuccinimide-ester-labelled antibody 1 ml, 1 mg ml−1 goat anti-rabbit immunoglobulin G (IgG) antibody (Huabio, HA1002) was dialysed (Viskase, Membra-Cel MD44) overnight at 4 °C in 3 l of 0.01 M phosphate buffer saline (PBS, pH 7.6, Sigma) and adjusted to a concentration of 2 mg ml−1. Then 1 mg of Ru(bpy)2(mcbpy-O-Su-ester)(PF6)2 (Aladdin, R131404) was dissolved
A needle approaches an egg (purple) during in vitro fertilization, which some clinics offer in combination with a procedure called mitochondrial replacement therapy. Credit: Zephyr/Scientific Photo Library A small number of fertility clinics around the world are offering a controversial treatment: a procedure to provide clients’ embryos with donated mitochondria as a way to increase
Mitochondria (green in this false-color transmission electron micrograph) may play a role in the physiological effects of microgravity.Credit: José Calvo/Scientific Photography Library Researchers have found that exposure to microgravity aboard the International Space Station causes mitochondria in human cells and worms to produce fewer proteins. The work also identified a previously unknown molecular pathway that
