title: [Cells of coelomic liquid and cells of different tissues of sea star Asterias rubens L. isolated from intact and post-traumatic animals: behaviour and proliferation under cultivation in vitro].
abstract: Proposed sources of coelomocytes in Asteroidea after traumatic injures are coelomic epithelium, axial organ or Tidemann's bodies. To study the involvement of cell division in the process, proliferation of cells from different tissues of starfish Asterias rubens L. has been studied after bromdeoxyuridine incorporation in vivo. To study the differentiation of coelomocytes in vitro a method for isolation and cultivation of different tissue cells has been worked out and cell behaviour and proliferation in culture has been analyzed. The reliable BrdU incorporation has been found in coelomic epithelium cells in vivo. Coelomocytes and coelomic epithelium cells behaviour in culture dependent on the post-trauma period after which the cells were loaded into the culture whereas no difference was revealed for axial organ and Tidemann's bodies cells. Two-month cultivation of coelomic epithelium cells resulted in formation of colony-like accumulations of the cells with high nuclear-cytoplasm ratio which of colony-like accumulation of the cells with high nuclear-cytoplasm ratio which incorporated BrdU. Thus, coelomic epithelium cells seem to be more promising object for the study of A. rubens cell differentiation in vitro.
