  • Title: [Experimental-morphological study of morphogenetic potencies of homogeneous aggregates of different types of cells from the freshwater sponge Ephydatia fluviatilis (L.)].
    Author: Nikitin NS.
    Journal: Ontogenez; 1977; 8(5):460-7. PubMed ID: 909680.
    Abstract:
    The morphogenetic potencies of somatic cells of the fresh-water sponge Ephydatia fluviatilis in the developing aggregates depend on their initial specialization and the number of cells in the aggregate. The aggregates of nucleolar amoebocytes consisting of 500 or more cells have the highest morphogenetic potencies. All main cell types can arise in the developing homogeneous aggregates of nucleolar amoebocytes. The fine structure of nucleolar amoebocytes at different stages of development of the homogeneous aggregates was studied by means of electron microscopy. The structural rearrangements are described which accompany the process of redifferentiation of the nucleolar amoebocytes in other cell types.
