If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

Researchers have found that the “mother” of all stem cells, known as totipotent stem cells, have a much slower rate of DNA replication, which helps improve their efficiency at differentiating into ...

A new LUMC study has changed our understanding of how cells work. Researchers have discovered that the CFAP20 protein acts as a kind of "traffic controller" on DNA. Without this protein, chaos ensues, ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...
