The purpose of this study is to develop a possible therapeutic approach for psychiatric disorders by neurogenesis upregulation through increase of peripheral hematopoietic stem cells. First, we have demonstrated that the combined peripheral treatment of stem cells and antidepressant, which has been indicated to increase trophic factors in the serum could have potential to recover the abnormal behavior of treatment-resistant refractory depression model. We have also shown that peripherally treated neural stem cells concentrated much in the hypothalamus areas where oxytocin/vasopresinergic neurons exist, and recovered social/cognitive impairment of psychiatric disease model including parental behavior.
