Scientists from the Francis Crick Institute in the UK have successfully developed human stem cell models that include a functional notochord, a vital structure for spinal and neurological development. This advancement offers new insights into early human development and the origins of related disorders. The research could pave the way for understanding genetic abnormalities affecting the spine and insights into conditions like disc degeneration. The study highlights the intricate process of creating a notochord in the lab, akin to perfecting a recipe, allowing for better understanding of developmental defects.
