Biologists have identified the specific region in vertebrates where adult blood stem cells arise during embryonic development. The researchers say their time-lapse imaging of the process, by which primitive embryonic tissues first produce the parent stem cells that produce all adult blood cells over the life of an individual, should help guide future efforts to repair and replace this cell population for therapeutic purposes.
