title: Bone cells in culture: morphologic transformation by hormones.
abstract: Hormones and purine nucleosides and nucleotides induced cultured bone cells to transform transiently from a spherical to a stellate shape. Cytochalasin B also induced the transformation. The change was blocked by colchicine and vinblastine, but not by lumicolchicine or cycloheximide. This morphologic transformation may provide a dynamic model of hormone action and bone cell modulation in vitro.
