Utilizing semi-thin and, respectively, thick sections after indian ink injections, we have analyzed morphohistogenesis and vessel development in the adenohypophysis of chick embryos from the 4th to the 19th incubation day. Our preliminary results indicate that a close correlation exists between cellular differentiation and vasculogenesis. Vessels begin to enter the gland only at the 6th day when the first endocellular granules become detectable, and, from the 10th day, they markedly increase in number and size, gradually acquiring a peculiar sinusoidal arrangement around cellular groups, as cell differentiation further progresses.
在注射印度墨汁后，分别利用半薄切片和厚切片，我们分析了鸡胚从孵化第4天到第19天腺垂体的形态组织发生和血管发育。我们的初步结果表明，细胞分化与血管生成之间存在密切关联。血管仅在第6天开始进入腺体，此时首次可检测到细胞内颗粒，并且从第10天起，它们的数量和大小显著增加，随着细胞分化进一步推进，逐渐在细胞群周围形成一种特殊的窦状排列。
