异足新米虾（Neocaridina heteropoda）（甲壳纲，软甲纲，十足目）起源于亚洲，是世界上广泛存在的物种之一，因为它是水族馆中最受欢迎的养殖虾。中肠的结构和超微结构已被描述使用X射线显微断层扫描，透射电子显微镜，光学和荧光显微镜。内胚层区是营养系统的内胚层区。异足纲动物由肠和肝胰腺组成。没有观察到差异的结构和超微结构的男性和女性的虾进行了检查。肠是一个管状器官，肝胰腺由两个大的憩室组成，分为盲端小管。肝胰管有三个不同的区域-近端，中间和远端。在肠的上皮细胞中，区分两种类型的细胞- D和E-细胞，而在肝胰腺的上皮中观察到三种类型的细胞- F、B和E-细胞。我们的研究表明，细胞活动的区域化发生沿着肝胰管的长度。所有类型的上皮细胞的作用和超微结构进行了讨论，特别强调的E细胞，这是中肠再生细胞的功能。此外，我们提出了第一份报告的存在与甲壳纲的E细胞的细胞间连接。
The freshwater shrimp Neocaridina heteropoda (Crustacea, Malacostraca, Decapoda) originates from Asia and is one of the species that is widely available all over the world because it is the most popular shrimp that is bred in aquaria. The structure and the ultrastructure of the midgut have been described using X-ray microtomography, transmission electron microscopy, light and fluorescence microscopes. The endodermal region of the alimentary system in N. heteropoda consists of an intestine and a hepatopancreas. No differences were observed in the structure and ultrastructure of males and females of the shrimp that were examined. The intestine is a tube-shaped organ and the hepatopancreas is composed of two large diverticles that are divided into the blind-end tubules. Hepatopancreatic tubules have three distinct zones – proximal, medial and distal. Among the epithelial cells of the intestine, two types of cells were distinguished – D and E-cells, while three types of cells were observed in the epithelium of the hepatopancreas – F, B and E-cells. Our studies showed that the regionalization in the activity of cells occurs along the length of the hepatopancreatic tubules. The role and ultrastructure of all types of epithelial cells are discussed, with the special emphasis on the function of the E-cells, which are the midgut regenerative cells. Additionally, we present the first report on the existence of an intercellular junction that is connected with the E-cells of Crustacea.
