New Technology Reveals Genetic Origin of Newborn Neurons in the Brain

Geneva, Switzerland (Scicasts) — Our brain is home to different types of neurons, each with their own genetic signature that defines their function. These neurons are derived from progenitor cells, which are specialized stem cells that have the ability to divide to give rise to neurons. Neuroscientists from the Faculty of Medicine at the University of Geneva (UNIGE) have now shed light on the mechanisms that allow progenitors to generate neurons. By developing a novel technology called FlashTag that enables them to isolate and visualize neurons at the very moment they are born, they have deciphered the basic genetic code allowing the construction of a neuron. This discovery, which was published March 3 in Science, allows us not only to understand how our brain develops, but also how to use…
