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 ...

CRISPR-Cas9 can generate unexpected, heritable mutations

CRISPR-Cas9, the "genetic scissors," creates new potential for curing diseases, but treatments must be reliable. In a new study, researchers have discovered that the method can give rise to unforeseen changes in DNA that ...

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 ...

Germ cell

Germ cells are progenitors of the gametes. These singled-out cells move through the gut to the developing gonads and undergo mitotic proliferation followed by meiosis and differentiation into either eggs or sperm (mature gametes). Plants do not have a germ line set aside in early development. Instead germ cells can come from somatic cells in the adult floral meristem.
