title: Cytasters from sea urchin eggs parthenogenetically activated by procaine.
abstract: A method is presented for the isolation of cytasters from unfertilized sea urchin eggs parthenogenetically activated by procaine. These cytasters do not appear to contain centrioles. The microtubules seem to grow out from the condensed chromosomes. The chromosomes have an unusual morphology.
