The classic origin story for a biotech startup is that of a scientist who nurtures his work out of a university and to commercial success. For Link Biologics Ltd. and its TSG6-based pipeline, the story is the other way around; it began with now-CEO Reuben Dawkins meeting University of Manchester scientists Tony Day and Caroline Milner while he was on the lookout for “great science that needs help to make it to patients.” The three are now co-founders of Link, which spun out of the University of Manchester in 2021 and has four programs in three indications, all based on TSG-6 biology.
