Most of our organs are constantly renewed through the involvement of stem cell population(s). These stem cells are strictly regulated to ensure a life-long homeostasis. The fine regulation of cell fate applied on stem cells to progenitors and finally terminally differentiated cells is instrumental to the organ function. Because of aging, disease, or injury, the organ homeostasis collapses, leading to a transitory or permanent organ failure. To restore the homeostasis, or to replace the whole organ, the tissue-specific cell fate needs to be well known at the molecular and population level.

Our aspiration is to decipher the molecular networks involved in cell fate acquisition, maintenance and differentiation to propose new regenerative medicine strategies.
