title: Oriented migration of interstitial cells and nematocytes inHydra attenuata.
abstract: The migratory properties of hydra cells within the tissue were studied. The extent and direction of cell migration were examined in budding, non-budding, and regenerating animals. Nematocytes and a small number of single big interstitial cells (the multipotent interstitial cells) actively migrate preferentially in an apical direction. Basal migration of these cells occurs only when a bud is present and, in which case, the cells migrate into the developing bud. The regeneration of the hypostome and tentacles does not affect cell migration in either direction, except for apical migration of stenotele nematocytes, which was markedly reduced.
