Abstract

Hematopoietic stem cells (HSCs) are perceived to reside at the top of a hierarchy in which HSCs possess self-renewal capacity and can progressively give rise to all blood lineage cells. Many findings consider calcium signalling as an extrinsic factor and a handful of studies show the direct role of calcium sensor in HSC regulation. We discuss how intracellular calcium (Cai 2+) pathway regulates and maintains HSC, from the aspect of relevant calcium sensor proteins. In the future, with a combination of advances in single cell technologies, low-input proteomic platform and spatialimaging will be hopeful approaches towards identifying the mechanism of Cai 2+ in HSC maintenance
