Fetal membranes at the end of pregnancy have been examined indirectly with the help of FITC labelled antibodies for the occurrence of different collagen types (I, II, III, IV) and their initial steps as well as fibronectin and laminin. The connective tissue of amnion and chorion is composed of collagen type I and p-III. Collagen type IV occurs only rarely. Despite of the borderline reticulin fibres are not the component of these mechanical resistant fibre-mats. In the PAS positive material, seen between the cells of the trophoblast, laminin and type IV collagen were found. It can be stated that the compound of the intercellular substance is of the same kind as the basement membrane.
在妊娠末期，借助异硫氰酸荧光素标记抗体对胎膜进行了间接检查，以检测不同类型胶原蛋白（I、II、III、IV型）的存在及其初始阶段，以及纤连蛋白和层粘连蛋白。羊膜和绒毛膜的结缔组织由I型和III型前胶原组成。IV型胶原蛋白仅偶尔出现。尽管存在交界性网状纤维，但它们并非这些机械抗性纤维垫的组成部分。在滋养层细胞之间可见的PAS阳性物质中，发现了层粘连蛋白和IV型胶原蛋白。可以说，细胞间物质的复合物与基底膜同类。
