## Abstract Cleavageโinitiating activity of various biological materials was tested by microinjection into unfertilized eggs of __Oryzias latipes__. Injection of intact sea urchin spermatozoa, their flagellumโ and centrioleโfractions induced cleavage of unfertilized eggs. On the contrary, injection
## Abstract Fractions of sperm homogenates from various animals (medaka, loach, toad, and rat) have been injected into unfertilized mature eggs of the medaka, __Oryzias latipes__, to test their cleavageโinitiating activity (CIA). The relationship between CIA and components of each fraction was also
## Abstract Mature unfertilized eggs of the medaka, __Oryzias latipes__, were injected with sperm flagellar microtubules of the sea urchin, __Hemicentrotus pulcherrimus__, and were observed with reference to the process of early development. Groups of injected eggs, most of which initiated cleavage
