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.
A study in mice done at IRB Barcelona and CNAG-CRG explains that dermal fibroblasts lose their cell identify over time and with it their capacity to produce and secrete collagen and other proteins.
A project headed by Antonio Zorzano at IRB Barcelona has been awarded funding from the BBVA Foundation to explore a possible link between ageing and cancer.
Called MitoFuss, the project focuses on the mitochondrial protein Mitofusin 2.
This weekend the Ciutadella Park will be hosting this event, which will showcase 230 scientific activities aimed at the general public.
IRB Barcelona will be participating through two workshops and a micro-talk, related to microscopy, cancer research and ageing.
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.
