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 ...

Cells in the body have to move around in order to do their jobs. During development, for instance, cells are distributed to create and grow tissue. And in the event of an immune response, different ...

Cells are constantly on the move, whether in a developing embryo or metastatic cancer. But how do cells adapt to new environments they encounter? Traditionally, scientists have believed that cells ...

Orthopedic non-invasive stem cell therapy regenerates damaged tissue rather than just improving symptoms. Autologous stem cell therapy uses cells from your own body, minimizing rejection risks.

Stem cells are the body’s ultimate shape-shifters, sustaining tissues by balancing two competing demands: maintaining their own population and generating specialized descendants. In many tissues, some ...

All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their basic functions. One of the most well-studied cellular responses is how ...

What researchers know of human cells is pieced together like a scrapbook full of snapshots: division here, fertilization there, with maybe a bit of differentiation in between. While scientists know ...

A long-standing mystery in cancer treatment is how tumor cells so often become resistant to drugs, even ones they have never encountered before.

Scientists are looking for answers about how these confounding trips, known as metastases, occur throughout the human body Illustration of a human cancer cell Amber Dance, Knowable Magazine Back in ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...
