By investigating motility and migration of adipose tissue (AT) stem/progenitor cells we are studying novel aspects of AT biology since this area of research is largely uncovered so far. We hypothesize that AT stem/progenitor cells are motile in vivo thus being able to invade other tissues in physiological or pathophysiological conditions. This research program might identify AT stem/progenitor motility as a potential target for AT physiology and physiopathology. Excessive AT development (referred to as obesity) is associated with ectopic fat deposition; known to induce metabolic disorders rather then obesity per se. Controlling the mobility of AT stem/progenitors might be a very exciting and unexplored approach to understand deleterious ectopic fat deposition.This research program is directly relevant in term of public health since obesity is a leading preventable cause of death worldwide with increasing prevalence. Finally, identifying molecular and cellular factors controlling AT stem/progenitor cell motility might also bring targets to ameliorate their use in regenerative medicine (optimisation of homing in damaged tissues).
