A team led by University of Osaka researchers has developed a technique to generate testes from mouse embryonic stem cells ...

Single-molecule imaging shows that three CBX2 protein molecules can seed Polycomb condensates that silence genes in stem cells. The discovery reveals how rare proteins organize genome regulation and ...

Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

How do cells acquire their identities? In hopes of answering this question, a Duke team recently completed a study explaining the expression of stem cells after a decade of research. Stem cells are ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Senescence. It’s a beautiful-sounding word whose tones suggest it should be a perfume or an essential oil. But that’s not even close. Senescence is the loss of a cell’s power to divide and grow, thus ...

Re “Stepping Out of Line in Stem Cell Research,” Commentary, Oct. 25: Yesterday I sent in my absentee ballot and voted yes on stem cell research. I did so with mixed feelings because this is high-tech ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Jennifer Zenker receives funding from NHMRC and Viertel Foundation. Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in ...

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...
