Discovery of genes involved in infertility mechanism

Most cells in the tissues of organisms proliferate through somatic cell division (mitosis). This is a continuous cycle by which a single cell doubles its genetic information (chromosomes) and divides equally to create two ...

Identification of all types of germ cells tumors

Germ cell tumors constitute a diverse group of rare tumors, which occur in the testes, ovaries and also in other places. Some germ cell tumors exist prenatally, while others present during or after puberty. The majority are ...

Ancient epigenetic changes silence cancer-linked genes

An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research ...

DNA repair gene linked to male infertility

A key DNA repair gene known as X-ray repair cross-complementing group 1, or XRCC1, plays a vital role in maintaining genomic stability and is highly expressed in the early stages of sperm cell development (also known as spermatogenesis). ...

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.
