For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

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 ...

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 ...

Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...

Cells in developing ovaries or testes support germ cells, which are central to sexual reproduction. These supporting cells are thought to send the signals that determine the fate of germ cells. One of ...
