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

When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

Organoids have transformed biomedical research by giving scientists miniature versions of human organs to study in the lab.

Human pluripotent stem-cells (HPSCs)—including human embryonic stem-cells and human induced pluripotent stem-cells—are reshaping the landscape of regenerative medicine.1,2 In Parkinson's disease, ...

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 ...

Researchers from the University of California San Diego Sanford Stem Cell Institute have discovered that spaceflight accelerates the aging of human hematopoietic stem and progenitor cells (HSPCs), ...

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 ...

Graham Johnson, a computational biologist and scientific illustrator at the Allen Institute for Cell Science, recalls fantasizing at a lunch table, more than 15 years ago, about a computer model of a ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...
