title: From blood to brain: the neurogenic niche of the crayfish brain.
abstract: Adult neurogenic niches are present in both vertebrates and invertebrates. Where do stem cells populating these niches originate, and what are the mechanisms maintaining their self-renewal? In this issue of Developmental Cell, Benton et al. (2014) show that in crayfish, hemolymph-derived cells enter a neurogenic niche to replenish neural progenitors.
