Egg cell (IMAGE)
Caption
Female mammals are born with all the egg cells they will ever have in their ovaries. Some of these cells therefore live for a long time – and must remain functional throughout this period. Experiments with mice have now shown: Extremely long-lived proteins in the ovary can keep egg cells healthy and preserve fertility for a long time. In the mouse egg cell shown here, the chromosomes are stained magenta and the cytoskeletal protein actin is stained blue and white.
