Abstract
An attempt to isolate an ooplasmic factor active in inducing pole cells in Drosophila embryos is described. With the help of a bioassay system, we demonstrated that RNA extracted from embryos was active in inducing pole cells. These RNA-induced pole cells were morphologically identical to the normal ones. In addition, a local application of cycloheximide suggests that translation in the posterior pole cytoplasm is a precondition for pole cell formation.Keywords
