Quantification of Cutaneous Ionocytes in Small Aquatic Organisms
[Abstract] Aquatic organisms have specialized cells called ionocytes that regulate the ionic composition, osmolarity, and acid/base status of internal fluids. In small aquatic organisms such as fishes in their early life stages, ionocytes are typically found on the cutaneous surface and their abundance can change to help cope with various metabolic and ...

[Abstract] Zebrafish have become an increasingly important model organism in the field of wound healing and regenerative medicine, due to their high regenerative capacity coupled with high-resolution imaging in living animals. In a recent study, we described multiple physical and chemical methods to induce notochord injury that led to highly specific ...
Zebrafish Embryo Xenograft and Metastasis Assay
[Abstract] Xenograft models, and in particular the mouse xenograft model, where human cancer cells are transplanted into immunocompromised mice, have been used extensively in cancer studies. Although these models have contributed enormously to our understanding of cancer biology, the zebrafish xenograft model offers several advantages over the mouse model. ...

[Abstract] We described a simple method for microinjecting DNA/RNA/Protein solutions into medaka eggs under an upright microscope. Medaka is an excellent vertebrate model for reverse genetics, because of its daily spawning, short generation time, and egg transparency. These features enable us to efficiently perform functional genomic analyses of transgenic ...
