The Role of Stem Cell Strategies in Coping with Environmental Stress and Choosing Between Alternative Reproductive Modes: Turbellaria Rely on a Single Cell Type to Maintain ­Individual Life and Propagate Species

Abstract: Abstract. To contribute to a better understanding of the interrelationships of different forms of asexual and sexual reproduction in the Turbellaria, three selected species were studied with respect to the cellular correlates underlying the diverse reproductive strategies. The exclusively asexual freshwater triclad Dugesia tahitiensis holds the top position in regenerative and fissioning capacities within the Tricladida and, in addition, has the most neoblasts (stem or regenerative cells) known within this ta… Show more

“…Funayama believes that both archaeocytes and choanocytes of sponges are pluripotent. Neoblasts of planarians are considered totipotent (Shibata et al, 1999;Gschwentner et al, 2001;Peter et al, 2001;Sköld et al, 2009) or pluripotent (Shibata et al, 2010). Similarly, stem cells of colonial rhizocephalan crustaceans can also be considered totipotent (Isaeva et al, , 2008b(Isaeva et al, , 2009Shukalyuk et al, , 2007 or pluripotent.…”

“…Interstitial cells in hydra and other cnidarians can produce both germline cells and some but not all somatic cell types, since epidermal and gastrodermal cells are also capable of mitotic reproduction; so the stem cell system in hydroids includes interstitial, epidermal and gastrodermal stem cells continuously undergoing the mitotic cycle (Campbell, 1974;Thomas & Edwards, 1991;Bode, 1996). For the identification of stem cells capable of mitotic reproduction, bromodeoxyuridine, a thymidine analogue, was successfully used to reveal DNA synthesis in interstitial cells in hydra (Teragawa & Bode, 1990), and neoblasts in flatworms (Gschwentner et al, 2001;Peter et al, 2001). Ethynyl deoxyurudine, another thymidine analogue, was employed for the same purpose in the ctenophore Pleurobrachia pileus (Alié et al, 2011).…”
