Cells naturally exchange cytoplasmic components like proteins, RNA, and mitochondria, but scientists lack tools to control such transfers in living cells. Now, researchers in Japan have developed a nanotube membrane-based injector—a system that enables high-efficiency, minimally invasive cytoplasmic transfer between cells. This platform preserves cell viability and can even transfer functional mitochondria, opening new possibilities for cell engineering and regenerative medicine.

A first-in-human trial from Institute of Science Tokyo and EVA Therapeutics, Inc., demonstrates that enteral ventilation, a technique that could deliver oxygen through the intestine, is safe and feasible in healthy subjects. The method involves intrarectal administration of an oxygen-carrying fluid into the gut, where oxygen may diffuse into the bloodstream. These findings provide important evidence for further testing of enteral ventilation as a potential alternative oxygenation method for patients with respiratory failure.
