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 ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

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 ...

In the same vein as weather forecast models that predict developing storms, researchers have now developed a method to predict the cell activity in tissues over time. The new software combines ...

We use our lips to talk, eat, drink, and breathe; they signal our emotions, health, and aesthetic beauty. It takes a complex structure to perform so many roles, so lip problems can be hard to repair ...

A newly identified virus–cell hybrid structure allows viruses to spread faster and more aggressively by hitching a ride on migrating cells. Viruses rely on efficient movement between cells to ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...
