The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, w...
Mature Sperm and Eggs Grown from Same Stem Cells, Reports on a series of experiments wherein scientists have transformed cells from mouse embryos into skin, heart muscle, and eggs. Political and ethical debate over whether similar experiment should be conducted with cells derived from ... NewsNat...
Reproductive cells cannot be stored at home. For egg and sperm cells to be available for later use, they have to be cryopreserved in special conditions. Moreover, in the case of egg freezing, surgery is necessary prior to storing the ova, so the woman has to visit an egg bank or fertil...

Some cells are set up to become stem cells, which will then have the potential to develop into any type of cell in the body. And some cells in the fetus become primordial germ cells and eventually evolve into the cells of either sperm or eggs, which will allow this offspring to pass th...
Like embryonic germ cells, which are cells that develop early in the formation of the fetus and that later generate eggs or sperm,embryonic stem cells have the ability of developing themselves into different kinds of body tissue. 选项:

that if they could copy it, they could coax any cell along the same path. Working mostly in rodents, these pioneers in so-called in vitro gametogenesis, or IVG, have since turned mice stem cellsinto sperm and eggs, including a recent success creatingeggs from the stem cellsof a male ...
