提供了从第8天到孵化的鸡胚胎红细胞正常成熟的数据。一般来说，红细胞的数量和存在的血红蛋白的数量是逐渐增加的，但单个细胞的血红蛋白含量并没有增加。详细介绍了这三种红细胞的变化关系。对于所研究的大多数方面，第8-10天和15-17天是变化最快的时期。关于细胞大小的数据与以前的报道有很大的不同，这似乎主要与本研究中使用尿囊静脉穿刺法获取标本以及使用肝素作为抗凝剂的技术有关。发现白细胞在血液循环中出现的时间比之前认为的要晚。较早的出现可能是由于夹层造成的创伤。
Data are presented on the normal maturation of the erythrocytes of the chick embryo from day 8 through hatching. There is in general a progressive increase in numbers of erythrocytes and in the amount of hemoglobin present, but not in the hemoglobin content of the individual cell. The changing relationship of the 3 types of erythrocyte is presented in detail. For most of the facets studied days 8-10 and 15-17 are the periods of most rapid change. Data on cell size differ significantly from previous reports and this seems related primarily to technique[long dash]the use of allantoic venepuncture to obtain specimens, and the use of heparin as an anticoagulant, in the present study. Leucocytes were found to appear later in the circulation than had previously been thought. Earlier appearance was probably caused by the trauma of dissection.
