La Vanguardia has asked ICREA researcher Salvador Aznar Benitah, an expert on stem cells and circadian rhythm, for his opinion about two studies published by British universities that suggest that skin regeneration is higher during the day than during the night.

The newspaper ABC has published an article about the group of scientists and medicsl doctors that is facing cancer. In the article, they mention Manuel Serrano, group leader of the Cellular Plasticity and Disease laboratory at IRB Barcelona, who affirms that the great challenge of regenerative medicine is to know how tissues react to damage and how they self-repair.

The research and science programme “Principio de Incertidumbre” broadcasted by Radio Canal Extremadura has interviewed the ICREA researcher Salvador Aznar Benitah about the circadian rhythm—the subject of the 2017 Nobel Prize in Medicine.
In August, Aznar Benitah’s group published two studies in Cell that rejected the dogma that aging is associated with the loss of the circadian cycle of stem cells.
How does the circadian clock change when we get older? This is the question that has driven research associate Guiomar Solanas and “la Caixa” PhD student Francisca Oliveira Peixoto, both at IRB Barcelona, to study the daily pattern of gene activity. The answer, as laid out in two studies headed by Salvador Aznar Benitah and published in the journal Cell, rejects the widely held belief that stem cells lose their circadian rhythm with age. The studies demonstrate that the daily pattern of gene activity is not lost with age but is rather reprogrammed for new functions and that a low calorie diet delays alterations in the rhythm of stem cells.
