| Outline of Final Research Achievements |
The main problem for mammalian reproduction experiments in space is the very small size of embryos (80-100 μm), which generally requires researchers to learn appropriate handling techniques. Presently, the thawing and culturing of embryos are difficult even on the ground, especially if the experimentalist has not had much practice. In addition, this project will be performed under μG conditions, which makes it difficult to predict how to handle the embryos. Therefore, it is not realistic to expect untrained astronauts to do this directly. For this reason, we have started to develop a very simple thawing and culture system of mouse embryos using commercially available products. Using this system, astronauts will not need to handle the embryos, and will not need prior training. To overcome the impracticality of handling and culturing mammalian embryos, we planned a simple embryo thawing and culture system, which will allow the astronauts to perform this project smoothly.
