By transferring mouse aged hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was demonstrated that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells. On the other hand, the function of aged HSCs did not recover in the young bone marrow niche.
