An epigenetic factor that is essential for producing mature egg cells in mice has been identified by RIKEN researchers for ...

Cell division, the basic means by which genetic information is passed from generation to generation, involves tightly coordinated movements of a cell's DNA. This page describes the major phases of ...

Scientists have used human skin cells to produce functional eggs using a new scientific technique they say could one day help ...

There is a high unmet need for accessible, affordable, and high-quality fertility care, as approximately 1 in 6 people are affected by infertility worldwide. While meiotic failure is a major cause of ...

The chromatids arrive at the either end of each cell and new nuclear membranes form. With meiosis in a female, there is only one dividing cell at this point. As in telophase I, the cytoplasm of the ...

How do we grow from a single fertilized egg into a fully grown person with trillions of cells? Our cells divide, of course! And it's no mean feat. Each time a cell divides, it must duplicate our 23 ...

Interphase is the period between cell divisions. During this time, chromosomes replicate—each DNA strand unzips into two strands while free-floating bases attach to the unzipped strands. The ...
