One step closer to artificial rhino eggs

To prevent the extinction of the northern white rhino, the international consortium BioRescue is attempting to create artificial egg cells from stem cells. A team led by MDC's Sebastian Diecke and Micha Drukker of Leiden ...

Gene repression can be sex-specific

Researchers have shown for the first time that embryonic cells destined to become either egg or sperm rely on different methods of repressive gene regulation.

Male-biased protein expression discovered in fruit flies

Fruit flies (Drosophila) are important model organisms for biological research. Molecular tools exist that can turn on (or induce) gene expression in fruit flies, allowing researchers to learn more about the functions of ...

Freezing fruit flies for future function

The fruit fly Drosophila melanogaster has long been an important experimental model for biological research. While you may be eager to rid your kitchen of this unwanted pest, researchers in Japan have developed a new technique ...

Patterns in primordial germ cell migration

Whenever an organism develops and forms organs, a tumor creates metastases or the immune system becomes active in inflammation, cells migrate within the body. As they do, they interact with surrounding tissues which influence ...
