Both the mouse OSCs and human DDX4-positive cells maintained in vitro generated spontaneous oocytes, and expressed known oocyte markers and, respectively, the mouse and human diploten-stage oocyte ...

Partly through the expression of specific genes, the oocyte-cumulus interaction helps the oocyte to acquire its developmental competence. Our aim was therefore to identify at the level of cumulus ...

Scientists Clone Mice From Adult Skin Stem Cells Date: February 12, 2007 Source: Rockefeller University Summary: Using a nuclear transfer procedure, scientists at Rockefeller University and the ...

By activating just eight genes for transcription factors, researchers at Kyushu University have directly converted mouse stem cells into oocyte-like cells that mature and can even be fertilized ...

South Korean and U.S. researchers said Wednesday they had cloned a human embryo and extracted from it sought-after cells called embryonic stem cells.

Elvan Böke, an oocyte biologist at the Centre for Genomic Regulation, and her team collected human oocytes to study how protein degradation contributes to the prolonged life of these cells. Shown here ...

A typical mammalian egg is surrounded by an outer layer of about 3,000 cumulus cells embedded in an extracellular matrix rich in hyaluronic acid. A current, widely proposed model is that the ...
