Scientists at the University of Cambridge working with the Weizmann Institute have created primordial germ cells - cells that will go on to become egg and sperm - using human embryonic stem cells. Although this had already been done using rodent stem cells, the study, published today in the jo...
The egg prevents more than one sperm from fertilizing it by disallowing the entry of any more sperms into the area near it. Firstly, a reaction...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tou...
planarians, during maturation divisions. In other cases, a new cell center is formed after fertilization from centrioles introduced by sperm or, infrequently, by new formation. Yolk inclusions are a specific constituent of the cytoplasm. The differences in amount and distribution of yolk in ...
The question at the centre of our research is How do sperm and egg transform into an embryo during fertilisation? This is still really unknown for any species. We study the problem in the mouse partly because it is possible to make experimental changes to mouse embryos to see what happens,...
Germ cells are the precursors of the gametes and are, therefore, critical for the survival of the species. Mature female (oocytes or “eggs”) and male (spermatozoa or “sperm”) germ cells are similar in that both are haploid cells derived from their diploid precursors by meiotic division,...

Genetic studies have identified many proteins that contribute to the first contact between egg and sperm. However, no direct evidence has yet demonstrated how these factors bind or form complexes to carry out their function as a “lock-and-key” mechanism. Now, Andrea Pauli’...
