Our work aims at understanding the control of stem cell function by organismal metabolism. We focus on adipose tissue mesenchymal stem/stromal cells (ASCs) - immature cells partly associated with the vasculature - which contribute to tissue remodelling by adopting different fates including the formation of new adipocytes. In particular, we are interested in the role of ASCs in nutrition-driven early adipose tissue growth, leading to childhood obesity and the programming of adult metabolic disease. In addition, we have been contributing major discoveries on the regulation of the oxidative/thermogenic adipocyte fate of ASCs, which is triggered by organismal cold exposure and conveys protection from metabolic disease.

Currently, we are investigating how the microenvironment senses and relays nutritional cues and systemic metabolic states to control ASC function and thereby adipose tissue quantity and quality. We envisage reaching conclusions relevant to the prevention and management of childhood obesity in relation to adult metabolic disease. Finally, we expect to obtain insight into common mechanistic links between organismal metabolism and normal versus neoplastic tissue growth.
