    Notes: Summary We describe a rapid method for the isolation of large numbers of livingHydra cells of defined cell type in an isotonic cell medium (Gierer et al. 1972). Intact animals are enzymatically dissociated into a single cell suspension and the various cell types separated in less than one hour by counterflow centrifugation elutriation. Cell loss is minimal. RNA isolated from various fractions can be probed with cell type specific cDNA-clones.

    Notes: Abstract We investigated morphology, dynamics and origin of cells surrounding the mouth of Hydra vulgaris using the monoclonal antibody L96. This antibody recognises a one cell-thick ring of endodermal epithelial cells exactly at the boundary between endoderm (gastrodermis) and ectoderm (epidermis). L96+ cells can stretch considerably without any cell rupture during mouth opening. Thus, our data prove the existence of a distinct cell population defining hydra's mouth. A model for mouth opening is proposed and the significance of L96+ cells for boundary formation between ectoderm and endoderm is discussed.
