Lymphohematopoietic Stem Cells and Their Aging
One underlying contribution to aging-associated immune remodeling might be aging of the stem cell that all immune cells are derived from, the hematopoietic stem cell (HSC). A defined canonical set of phenotypic and functional features separates young from aged HSCs. Molecular mechanisms that contribute to aging of HSCs have been recently identified and comprise stem cell-intrinsic mechanisms as well as influences stemming from an aged stem cell niche. Aging of stem cells is reversible, and rejuvenation of aged HSCs might contribute to healthy aging.
