Researchers at the Francis Crick Institute have shown that gonadotrophs, cells in the pituitary gland with a key role in puberty and reproduction, come from two different populations, with the ...

Scientists Found Cells That Defy the Rules of Reproduction—and Could Change Biology Mitosis is no longer just what you learned in high school.

Maybe you remember high school biology. It was probably then that you learned about cells dividing through mitosis, and mentally repeated the terms interphase, prophase, metaphase, anaphase ...

Explore how DNA gets sorted into sperm cells and egg cells. What’s special about sex cells? Figure out how they’re made (in a process called meiosis), and learn why it matters. You will see four ...

Recombinase DMC1, first described in yeasts and found to play a central role in recombination events, synaptonemal complex formation, and cell cycle progression (Bishop et al., 1992), belongs to the ...

Researchers are inching closer to creating human eggs and sperm in the lab that carry a full complement of anyone's DNA. It could revolutionize fertility treatment and raises huge ethical questions.

NPR Creating a sperm or egg from any cell? Reproduction revolution on the horizon Researchers are inching closer to creating human eggs and sperm in the lab that carry a full complement of anyone ...

Sperm and eggs are produced by meiotic cell division. The central events in meiosis include homologous chromosome (homologs) pairing, synapsis, recombination and segregation. During meiotic ...

Further advances to the production of synthetic reproductive cells and even organisms in 2023 could boost our understanding of human fertility and why many pregnancies don’t reach full term.

A study from Karolinska Institutet in Sweden, among others, presents the theory that egg-sperm fusion, a crucial feature of sexual reproduction in plants and animals, may have originated from an ...
