Hematopoietic stem cells (HSCs) are critical for maintaining lifelong blood production and immune function, especially in the context of bone marrow transplantation, where their ability to reconstruct multiple blood lineages is essential. However, recent studies have revealed that certain HSCs exhibit a bias toward platelet differentiation, termed platelet-biased HSCs (P-HSCs). This lineage bias, particularly pronounced with aging, can lead to imbalances in post-transplant blood recovery, negatively affecting patient outcomes. Research by Claus Nerlov's team has provided key insights into the heterogeneity of HSCs, focusing on the age-related expansion of P-HSCs. Using advanced techniques such as single-cell RNA sequencing and molecular barcoding, their work highlights the evolutionary conservation of platelet bias in HSCs across species. This work delves into these findings, discussing their clinical implications for bone marrow transplantation, aging-related blood disorders, and potential therapeutic strategies. Moreover, we address limitations in current methodologies and propose future directions for research to optimize HSC-based therapies and improve clinical outcomes in hematological diseases.
