Intestines modify their cellular structure in response to diet

Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie's Rebecca Obniski, ...

How intestinal cells renew themselves

The intestine must be able to renew itself to recover from environmental insults like bacterial infections. This renewal is made possible by a small number of intestinal stem cells which divide and produce daughter cells ...

It's all about the (stem cell) neighborhood

Stem cells have the ability to develop, or differentiate, into the many cell types in the body. They also serve as a repair system to replace aged or damaged cells. With their regenerative abilities, stem cells offer enormous ...

Clock mystery from 350 years ago is shedding light on human health

In 1665, the inventor of the pendulum clock, Christiaan Huygens, noticed that two of his clocks hung on the same wall would eventually sync up, so that their pendulums swung in opposite directions in perfect time. This "insensible ...

Study resolves long-disputed theory about stem cell populations

Adult stem cells represent a sort of blank clay from which a myriad of different cell and tissue types are molded and as such are of critical importance to health, aging and disease. In tissues that turn over rapidly, such ...

Biologists find how plants reconstitute stem cells

Stem cells are typically thought to have the intrinsic ability to generate or replace specialized cells. However, a team of biologists at NYU showed that regenerating plants can naturally reconstitute their stem cells from ...
