Abstract
Regulation of hematopoiesis is dependent upon interactions between hematopoietic stem/progenitor cells and niche components, requiring a highly diverse array of different cell-cell interactions and cell signaling events. The overwhelming diversity of the components that can regulate hematopoiesis, especially when factoring in how the cell surface and intracellular protein expression profiles of hematopoietic stem/progenitor cells and niche components differ between homeostatic conditions and stressed conditions such as aging and irradiation, can make utilizing techniques like flow cytometry daunting, particularly while examining small cell populations such as hematopoietic stem cells (HSCs). Due to the complexity of the hematopoietic system, high-dimensional single-cell genomics and proteomics are constantly performed to understand the heterogeneity and expression profiles within this system. This chapter describes one such single-cell assay, which utilizes mass cytometry Time of Flight (CyTOF) technology to determine differences in expression profile within HSC, using changes in HSC populations due to gender and aging.
