Adult stem cells ensure maintenance of the tissue and integrity in response to damage. They self-renew, are multipotential, and respond to and repair injuries.

Ageing is exacerbated by alterations of stem cell circadian rhythm

Stem cell functions continue to be governed by day and night cycles (circadian rhythms) during ageing, but their rhythms become devoted to tissue repair and not to the maintenance of tissue tone.

The two studies published in Cell and headed by Salvador Aznar Benitah at IRB Barcelona reject the scientific dogma associating ageing with the loss of stem cell circadian rhythm.

A low-calorie diet delays alterations in the rhythmic functions of stem cells and slows down ageing.

Researchers discover a protein that protects against fatty liver

It is a disease of the liver caused by excessive fat deposits in liver cells.

It is now the most prevalent chronic liver disease in industrialised countries and is a major public health concern because it leads to serious liver conditions.
