The colonial internae of two decapod parasites Peltogasterella gracilis and Sacculina polygenea (Crustacea: Cirripedia: Rhizocephala) were studied in vitro by histological, and histochemical methods. We found stem cells, characterized by basophilic cytoplasm, a large nucleus and nucleolus, and a high alkaline phosphatase activity. The cytochemical manifestation of alkaline phosphatase activity in totipotent stem cells of the colonial rhizocephala is the first evidence of commonality in the functional characteristics of embryonic stem cells in vertebrate and invertebrate animals of such different taxa as the mammals and Crustacea.
采用组织学和组织化学方法，在体外对两种十足目寄生虫——细弱囊腺介虫（Peltogasterella gracilis）和多基因根头目虫（Sacculina polygenea，甲壳纲：蔓足亚纲：根头目）的群体内体进行了研究。我们发现了干细胞，其特征为嗜碱性细胞质、大细胞核和核仁，以及高碱性磷酸酶活性。群体根头目的全能干细胞中碱性磷酸酶活性的细胞化学表现，首次证明了在哺乳动物和甲壳纲等不同分类群的脊椎动物和无脊椎动物中，胚胎干细胞功能特征具有共性。
