Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

“For many cell-based therapies, progress comes from connecting the right pieces at the right moment,” Klein said. “When biology, computation, and the right support come together, you can start to move ...

Meanwhile, medical research has changed. We can now study human disease using patient-derived cells, human organoids, advanced imaging and computational tools that reveal mechanisms we could not see ...

King's College London researchers have created a unique collection of human stem cell models that could help to uncover why ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

In a recent study, researchers manipulated cellular proteins that control genes in aged mice. Experimental results showed their livers were rejuvenated to younger states. This work shows promise as a ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells.

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely ...
