Our body is constantly repaired and renewed by tissue-specific stem cells (aka. adult stem cells). In order to secure tissue homeostasis, generation of new stem cells via self-renewal and their differentiation into functional cells must be carefully balanced. As we age, the capacity of stem cells declines.
Our laboratory studies both stem cell-intrinsic and extrinsic mechanisms altering tissue renewal capacity, and how such mechanisms ultimately result in the functional decline we recognize as aging.
Our main focus areas are:
