Changes in the erythrocyte population during postnatal development of the opossum have been studied. At birth, the red cells of the peripheral blood number less than 600,000/cmm and the characteristic erythrocyte is a large nucleated cell ('megaloblast'). These are rapidly replaced by smaller, nonnucleated cells. The results indicate that the yolk-sac period of blood formation is short and that the hepatic phase of hemopoiesis begins prior to birth. The data also suggest that megaloblasts in the opossum may be able to transform into megalocytes.
对负鼠出生后发育过程中红细胞群体的变化进行了研究。出生时，外周血红细胞数量少于600,000/立方毫米，特征性红细胞是大的有核细胞（“巨幼红细胞”）。这些细胞迅速被较小的无核细胞取代。结果表明，卵黄囊造血期很短，肝脏造血期在出生前就开始了。数据还表明，负鼠中的巨幼红细胞可能能够转化为巨红细胞。
