title: [Recognition of stem cells in the colonial internae of the Rhizocephala Peltogasterella gracilis and Sacculina polygenea at the parasitic life cycle stage].
abstract: 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.
