Separation of the sperm agglutinin and the acrosome reaction-inducing substance in egg jelly of starfish.
The egg jelly of the starfish Asterias amurensis was separated into the fractions J1, J2, and J3 on a Sephadex G-100 column. The Jl fraction induced the acrosome reaction and J2 induced sperm agglutination. Chemical analysis and chromatography revealed that sperm agglutinin is similar to asterosaponin A.
متن کاملThe Acrosome Reaction In
Suspensions of Mytilus edulis eggs were fixed with osmium tetroxide at various intervals between 1 and l0 seconds after heavy insemination, and sectioned for electron microscopy to follow the natural process of acrosome reaction in the spermatozoa around the eggs. Sperm suspensions were also fixed after the addition of I0 per cent by volume of M/3 calcium chloride. Within the first second after...
متن کاملThe effect of platelet activating factor on the motility and acrosome reaction of ram spermatozoa
Platelet activating factor (PAF) is a novel signaling phospholipids that in addition to platelet activation has many biological properties. The acrosome reaction, as an essential step in mammalian fertilization, can occur in response to several agents such as PAF. Therefore, the present study aimed to assess the effect of PAF on the motility and acrosome reaction of ram spermatozoa. Semen was c...
متن کاملRegulating the acrosome reaction.
The acrosome reaction is a secretory event that must be completed by the sperm of many animal species prior to fusion with eggs. In mammals, exocytosis in triggered by ZP3, a glycoprotein component of the egg pellucida, following gamete contact. ZP3 promotes a sustained influx of Ca2+ into sperm that is necessary for the acrosome reaction. Here, we discuss the mechanism by which ZP3 generates C...
متن کاملModulation of spermatozoon acrosome reaction.
Spermatozoon acrosome reaction is an exocytotic event of the utmost importance for the development of mammalian fertilisation. Current evidence shows that the triggering of the acrosome reaction (AR) could be regulated by the action of diverse compounds, namely, metabolites, neurotransmitters and hormones. The aim of the present review is to describe the modulating effects of several compounds ...
