Lab-Grown Pineal Gland Organoids Successfully Produce Melatonin

Researchers at Yale School of Medicine have successfully developed functional pineal gland organoids that produce melatonin, marking a significant advancement in organoid technology. The pineal gland is a small brain structure that regulates sleep patterns through melatonin production. These lab-grown organoids offer a new experimental model for studying sleep disorders and circadian rhythm regulation. Over the past two decades, scientists have created organoids for various organs including the gut, lung, liver, mammary gland, and brain, but functional pineal gland organoids represent a novel addition to this growing field of research.
