【#Tech24H】A research team from Cincinnati Children’s Hospital in the United States and the University of Nantes in France has developed a novel 3D-printed culture system capable of growing larger, more complex human intestinal organoids twice as fast as previous methods, with these organoids even developing their own nervous systems. For example, in just 14 days, the new system produced all cell types and tissue structures that previously took 28 days to form. The resulting small intestine, colon, and stomach organoids reached centimeter scale, nearly ten times larger than tissues grown with previous methods. This improved technology is expected to accelerate the production of “mini human tissues” large enough to repair damaged functions in the human small intestine, stomach, and colon. Such tissues could also be used in disease research in the future, offering more accurate assessments of the risk of organ damage from oral medications, among other applications.  [ By Zhang Liyan | Tang Ruohan ]
