Researchers transform common cell to master heart cell

By genetically reprogramming the most common type of cell in mammalian connective tissue, researchers at the University of Wisconsin-Madison have generated master heart cells—primitive progenitors that form the developing ...

Mini synthetic organism instead of test animals

In medical research, animal-based experiments have thus far been a necessary evil. Fraunhofer researchers have developed a highly promising alternative, however: They are developing a mini-organism inside a chip. This way, ...

Fleas collected from Norway rats in downtown LA carry human pathogen

Most fleas collected from rats trapped in downtown Los Angeles, California carried microbes from the genus, Bartonella, many of which are human pathogens, according to a paper in the November Applied and Environmental Microbiology. ...

Image: Human endothelial cells experiment bound for ISS

Components of human endothelial cells stained for identification. In red is the 'actin' protein that allows the cells to move, adhere, divide and react to stimuli. In blue are the cell nuclei containing DNA.

A human endothelial cell that was flown to the International Space Station and returned to Earth for analysis is helping researchers keep astronauts healthy in space.

Study identifies a key protein in blood vessel growth

Blood vessels are responsible for the appropriate and efficient delivery of nutrients and oxygen to the whole body. To do so, they must grow and branch to reach every cell in a process called angiogenesis. The precise regulation ...
