From blood to brain: the neurogenic niche of the crayfish brain
1Department of Molecular Cell and Developmental Biology, University of California Los Angeles, Los Angeles, CA 90095, USA.
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.
