Programmed reactivation of the inactive X chromosome in mammals happens in female primordial germ cells (PGCs) to prepare for meiosis and the generation of haploid germ cells that contain a single ...

A newly found organelle, the hemifusome, helps manage cellular recycling. It may play a role in inherited diseases and open ...

Hemifusomes are fused vesicles, or sacs of fluid, that were previously unknown to exist inside cells. They were discovered ...

Each time a cell divides, a small section of each chromosome's protective cap—the telomere—is worn away. Most cells use an enzyme called telomerase to help mitigate this loss, but 10% to 15% ...

By using a genetic technique developed at UT Southwestern Medical Center that forces cells to rid themselves of mitochondria, researchers are gaining new insights into the function of these critical ...

Specialized structure, dubbed a “hemifusome” by University of Virginia School of Medicine and the National Institutes of ...

A new organelle has been discovered in human cells — and scientists call it a "hemifusome." Like the full-size organs in our bodies, the organelles within cells are specialized structures that carry ...

Cell biology is a world of constant motion and hidden structures. Much of what we know about cells comes from decades of research using microscopes, stains, and models. Yet, even in this well-charted ...
