Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...

In Brief: The authors present ‘RETFound’, a self-supervised learning approach that has so far analysed 1.6 million retinal images to enable disease detection. RETFound shows good accuracy for diagnosis and prognosis of sight-threatening eye diseases. It also contributes to incident prediction of complex systemic disorders such as heart failure and myocardial infarction.The well-known saying ‘the eyes are the window to the soul’ means ...
