Egg Membrane Lytic Activity Of Sperm Extract And Its Significance In Relation To Sperm Entry In Hydroides Hexagonus (Annelida), Arthur L. Colwin, Laura Hunter Colwin
Egg Membrane Lytic Activity Of Sperm Extract And Its Significance In Relation To Sperm Entry In Hydroides Hexagonus (Annelida), Arthur L. Colwin, Laura Hunter Colwin
Publications and Research
Previous electron microscope studies indicated that the individual spermatozoön of Hydroides hexagonus forms a hole in the vitelline membrane by means of lysis. Other observations established that the hole is real, being visible in living material during sperm entry. During the present investigation sea water extracts from frozen-thawed sperm were tested for lytic effect on the membrane. In normal living eggs the membrane appears as a single thick envelope, but in electron micrographs of sections it is seen to consist of a narrow outer border layer, a wide principal or middle layer, and a narrow inner border layer. After immersion …
Formation Of Sperm Entry Holes In The Vitelline Membrane Of Hydroides Hexagonus (Annelida) And Evidence Of Their Lytic Origin, Laura Hunter Colwin, Arthur L. Colwin
Formation Of Sperm Entry Holes In The Vitelline Membrane Of Hydroides Hexagonus (Annelida) And Evidence Of Their Lytic Origin, Laura Hunter Colwin, Arthur L. Colwin
Publications and Research
Electron micrographs of inseminated eggs of Hydroides hexagonus previously had shown that in the immediate vicinity of the penetrating spermatozoön a small portion of the vitelline membrane regularly was absent, and it had been suggested that this area was a hole made by lytic activity of the individual spermatozoön during the course of its passage through the membrane. This deduction would receive support if it could be established that a sperm entry hole does form in living material. During the present study a hole repeatedly observed and photographed in the membrane of living eggs was found to arise as the …
