[Regulation of histogenesis in the axial organ of echinoderms (Echinodermata) according to findings from diffusion chamber cultivation].
Fragments of axial organs of different echinoderms were cultivated together with the gonad epithelium in the diffusion chambers made of millipore filters impermeable for cells (VUFS). Under these conditions, the histogenesis of amoebocytes suffered definite changes: the number of middle amoebocytes increased 2-3 times and that of large amoebocytes decreased correspondingly. Similar results were obtained not only under the direct contact of two tissues, but also under the contact realized through the millipore filter impermeable for cells. Corticosteroid agents of vertebrates did not influence the histogenesis of amoebocytes in Echinodermata.
