The thymus of 18-day-old normal-chick embryos, partially decerebrated chick embryos, and partially decerebrated embryos bearing hypophyseal allografts were analysed by light and transmission electron microscopy. The hypophyseal influence on the cytological differentiation of epithelial components has been studied. The thymus of partially decerebrated embryos showed a delayed differentiation of some types of epithelial cells and a marked decrease in number of lymphoid cells. Partially decerebrated embryos with hypophyseal implants showed a consistent recovery in the degree of differentiation of epithelial components. These findings indicate the influence of the hypophysis in establishing a correct environment for stromal cell differentiation.
对18日龄正常鸡胚、部分去脑鸡胚以及带有垂体同种异体移植的部分去脑鸡胚的胸腺进行了光镜和透射电镜分析。研究了垂体对上皮成分细胞分化的影响。部分去脑鸡胚的胸腺显示某些类型上皮细胞的分化延迟，淋巴细胞数量显著减少。带有垂体植入物的部分去脑鸡胚上皮成分的分化程度呈现出持续的恢复。这些发现表明垂体在为基质细胞分化建立正确环境方面的影响。
