Researchers have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies for conditions such as liver failure and type 1 diabetes. The study used nanoscale pH sensors and MRI machines to tell if liver cells injected into mice survived over time.
