Ageing & Tissue Repair – Stem Cell Ageing

Ageing is characterized by a decline in the organism’s physiological integrity and vulnerability to disease. Although the consequences of ageing on human health are broadly apparent, the causes and drivers of the ageing process are just beginning to be understood. An important hallmark of ageing is the loss of regenerative capacity that results from age-related changes in the systemic environment and the niche, as well as intrinsic limitations of stem cells themselves. Thus, the success of regenerative therapies in age-related diseases depends on combined strategies targeted at overcoming these interacting roadblocks to tissue repair in ageing.

In the Sousa-Victor Lab we use muscle ageing as a model system to understand mechanisms of stem cell ageing. We are currently working on three main research lines that aim to integrate knowledge of intrinsic mechanisms that drive stem cell loss of function with age (i) with immune-derived signaling in muscle regenerative responses (ii) to devise combinatorial approaches for improving the success stem-cell based therapies applied to the sarcopenic muscle (iii).

The Sousa-Victor lab is part of the Ageing & Tissue Repair joint lab, running two independent, complementary and cooperative research programs led by two group leaders: The research program in Sousa-Victor Lab aims to understand intrinsic limitations of aged stem cells. The Neves lab is focused on inflammatory signaling in ageing and immune modulatory strategies to improve regenerative success. Our goal is to apply the insights from the study of alterations in the ageing immune environment and stem cell ageing to develop new stem cell-based therapies to improve the health of old individuals. By studying stem cell function and immune modulatory mechanisms in an integrated manner, rather than as independent problems in the biology of tissue repair, we aim to provide a better understanding of the problems and optimized strategies for stem-cell based therapies in aging.

The Ageing & Tissue Repair joint lab uses Drosophila and in vitro models as platforms for screening, discovery and mechanistic studies, which are then translated into functional studies using mouse models and validated in human samples.
