When old hematopoietic stem cells get damaged
Abstract
Hematopoietic stem cells (HSCs) functionally decline and are prone to lineage bias and myeloid malignancies upon aging. Two recent studies (Beerman et al., 2014; Flach et al., 2014) investigate the underlying mechanisms associated with aged HSC phenotypes and highlight DNA damage, replication stress, and ribosomal stress in the process.
