Inflamm-aging of hematopoietic stem cells

Hematopoietic stem cells (HSCs) are responsible for generating all blood cells throughout life. Apart from the role of HSCs in maintaining the homeostasis of blood cell production process, they must respond quickly to hematopoietic challenges, such as infection or blood loss. HSCs can be directly/indirectly activated and engage in blood formation for the acute needs in response to inflammation. Recent findings highlight the emerging role of inflammation signaling on HSC fate decision and shaping the hematopoietic system during aging. Here, we summarize recent studies identifying the changes in inflammation and their role in modulation of HSC function and discuss the interaction between inflammation and HSC biology in the contexts of aging and hematological malignancy.
