science 🧠 Harvard grew lab brains for 7 years to track diseases
Scientists successfully kept lab-grown human brain organoids alive for an unprecedented seven years. This research was conducted by Paola Arlotta’s team at the Harvard Stem Cell Institute. The organoids tracked developmental time with accuracy, matching human brain stages from gestation through early childhood. This offers a window to watch long-term pathologies like Alzheimer’s develop without waiting decades. Future applications involve testing CNS gene therapies in these advanced models.
