Elongation of microvilli and formation of actin filaments after treatment with a phorbol ester, TPA, were investigated in unfertilized eggs of Hemicentrotus pulcherrimus. Microvilli on the egg surface were examined by scanning electron microscopy. Actin filaments in the cortical layer of the eggs we

Three years ago I showed that if the unfertilized eggs of the sea urchin Strongylocentrotus purpuratus are exposed for a minute o r longer to a solution of non-electrolyte (urea or glycerol), isosmotic with sea water and at a p H of 7 or 8, such eggs lose irreversibly the power of forming membranes
Changes in the intracellular Ca2+ concentration ([Ca2+]i) and the formation of actin filaments were investigated in unfertilized eggs of the sea urchin Hemicentrotus pulcherrimus after activation with a phorbol ester, 12-O-tetradecanoyl phorbol13-acetate (TPA). Intracellular Ca2+ oscillation was obs
I n a recent paper it was reported(1) that the fragility of certain mammalian erythrocytes is increased by testicular extract. In the last analysis such a change in erythrocytes signifies an increase in their permeability to hemoglobin. Since there was a certain amount of evidence from the work of D
