| Summary: | <p>Abstract</p> <p>Background</p> <p>Large volumes of lymph can be collected from the eye-sacs of bubble-eye goldfish. We attempted to induce vitellogenin (Vtg) in the eye-sac lymph of bubble-eye goldfish and develop a method for visualizing Vtg incorporation by zebrafish oocytes using FITC-labeling.</p> <p>Methods</p> <p>Estrogen efficiently induced Vtg in the eye-sac lymph of goldfish. After FITC-labeled Vtg was prepared, it was injected into mature female zebrafish.</p> <p>Results</p> <p>Incorporation of FITC-labeled Vtg by zebrafish oocytes was detected in <it>in vivo </it>and <it>in vitro </it>experiments. The embryos obtained from zebrafish females injected with FITC-labeled Vtg emitted FITC fluorescence from the yolk sac and developed normally.</p> <p>Conclusion</p> <p>This method for achieving Vtg incorporation by zebrafish oocytes could be useful in experiments related to the development and endocrinology of zebrafish oocytes.</p> |
