| Outline of Final Research Achievements |
The role of the blastocoel in early embryos are unknown. In this study, we hypothesized that it functions as the space which is used for signaling between tissues or for cell proliferation, and tried to verify this using proteomics of the blastocoel fluid.
We identified proteins that are involved in iron ion transport or homeostasis, proteinases, etc. However, we could not detect ligand proteins involved in cell signaling, and our hypothesis was not supported. The results suggested that the blastocoel may be utilized as a pool to digest unnecessary proteins during early embryogenesis.
