Human cells are extremely small and tightly packed – at about 20 micrometers across, ...

The most complex engineering of human cell lines ever has been achieved by scientists, revealing that our genomes are more resilient to significant structural changes than was previously thought. The ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

RAB7A plays a central role in the final stages of autophagy, facilitating autophagosome-lysosome fusion, lysosome positioning, and cargo degradation. Its activation by guanine nucleotide exchange ...

Assessing the toxicity of food contaminants—including carcinogenic potential—is a major challenge in evaluating the risks ...

Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...

Typically, bone marrow research relies heavily on animal models and oversimplified cell cultures in the laboratory. Now, researchers from the Department of Biomedicine at the University of Basel and ...

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 ...

Researchers at the Icahn School of Medicine at Mount Sinai have characterized how cellular senescence—a biological process in which aging cells change ...

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production ...
