| Outline of Final Research Achievements |
In this study, we aimed to generate culture cells of chipmunk neuron and to prepare a platform for elucidating molecular mechanisms of hibernation in vitro. First of all, we established the breeding system of chipmunk based on observation of chipmunk’s mating behavior to obtain chipmunk’s embryo. A female unique estrus call played a role in acceptance of male and copulation success. Through systematic mating experiments referring to female estrus call, we were able to obtain fresh chipmunk’s embryos from some pregnant females and provide them to subsequent culturing experiments. As a notable output for culture cells, we have succeeded to establish the culture system of chipmunk neural stem cells (neurosphere). These cells can be stored in LN. When necessary, cells are thawed and differentiated into mature neurons by appropriate procedures. We also make the culture device that does not require CO2. It makes low temperature culture easily without CO2 incubator.
