The medaka, Oryzias latipes is a useful animal model for the study of primary vasculature in vertebrate embryos. Using benzidine stain for erythroid cells, we found presumptive erythropoietic foci in the yolk sac vitellolysis zone at stage 39. These foci were present in the yolk syncytial layer, in the extravascular and vitellolysis zone from 9 days post fertilization (dpf) to 11 dpf, and then declined between 12 to 13 dpf with yolk mass depletion. A table of previous reports on various species of fish showing yolk sac erythropoiesis is also presented.
青鳉（Oryzias latipes）是研究脊椎动物胚胎初级血管系统的一种有用的动物模型。使用联苯胺对红细胞进行染色，我们在第39阶段的卵黄囊卵黄溶解区发现了推定的造血灶。这些造血灶存在于卵黄合胞体层、受精后9天（dpf）至11 dpf的血管外卵黄溶解区，然后在12至13 dpf随着卵黄质量的消耗而减少。还列出了先前关于各种鱼类卵黄囊造血的报告表格。
