Pregnancy-Stimulated Neurogenesis in the Adult Female Forebrain Mediated by Prolactin
Tetsuro Shingo,*Christopher Gregg,Emeka Enwere,Hirokazu Fujikawa,Rozina Hassam,Colleen Geary,James C. Cross,Samuel Weiss
Neurogenesis occurs in the olfactory system of the adult brain
throughout life, in both invertebrates and vertebrates, butits
physiological regulation is not understood. We show that theproduction
of neuronal progenitors is stimulated in the forebrainsubventricular
zone of female mice during pregnancy and that thiseffect is mediated
by the hormone prolactin. The progenitors thenmigrate to produce new
olfactory interneurons, a process likelyto be important for maternal
behavior, because olfactory discriminationis critical for recognition
and rearing of offspring. Neurogenesisoccurs even in females that mate
with sterile males. These findingsimply that forebrain olfactory
neurogenesis may contribute toadaptive behaviors in mating and
pregnancy.
