Scientists are growing heart cells in the laboratory to develop an AI tool that can detect disease in heart cells more quickly. The team at the University of East London is looking at how cells in the heart become defective during ageing. “One of the hardest things with the heart is its low regenerative capacity. So the heart has a turnover of heart cells, at a very low rate of 1 per cent, and by the time we reach 80 years of age that significantly decreases by almost half,” said Prashant Jay Ruchaya, a cardiovascular scientist at the University of East London.
