Human stem cells converted to functional lung cells

For the first time, scientists have succeeded in transforming human stem cells into functional lung and airway cells. The advance, reported by Columbia University Medical Center (CUMC) researchers, has significant potential ...

A new molecular guardian of intestinal stem cells

Intestinal stem cells hold a fine balance between two potential forms: remaining as stem cells, or developing into intestinal epithelial cells. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered ...

Space travel can make the gut leaky

Bacteria, fungi, and viruses can enter our gut through the food we eat. Fortunately, the epithelial cells that line our intestines serve as a robust barrier to prevent these microorganisms from invading the rest of our bodies.

Cell-killing proteins suppress listeria without killing cells

New North Carolina State University research shows that key proteins known for their ability to prevent viral infections by inducing cell death can also block certain bacterial infections without triggering the death of the ...

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 ...

A single-cell breakthrough

The human gut is a remarkable thing. Every week the intestines regenerate a new lining, sloughing off the equivalent surface area of a studio apartment and refurbishing it with new cells. For decades, researchers have known ...
