Like a magician, the freshwater flatworm known as planaria can survive decapitation or even being cut into many pieces. Its ability to fully regenerate from tiny remnants of tissue is due to a special population of adult stem cells known as neoblasts.  Scientists have spent decades studying the mechanisms that drive this remarkable feat, with the hopes that any secrets they uncover might lead to … Continue reading Elusive key molecular signal for planarian stem cell regeneration identified.
