A Single-Cell Immunofluorescence Method for the Division Patterns Research of Mouse Bone Marrow-Derived Hematopoietic Stem Cells.

How hematopoietic stem cells (HSCs) maintain the balance of self-renewal and differentiation could be partially ascribed to asymmetric and symmetric division patterns. However, a simple and effective method to detect stem cell division patterns is lacking. In this study, we introduce a strategy to describe stem cells division patterns with high spatial resolution at the single-cell level.

[Advances of studies on Purification and Tracking of Hematopoietic Stem Cells Using Their Specific Gene Expression--Review].

Hematopoietic stem cells (HSC) maintain homeostatic hematopoiesis via their multi-lineage differentiation and self-renewal potentials. HSC can be enriched and purified by flow cytometry relying on their cell surface markers and functional characteristics, however, these methods can not meet the need for deep analysis of HSC biological property and function because of the poor purity. Recent studies have successfully purified and tracked HSC using specifically expressed genes, which can enhance the purification efficiency of HSC, thus provide a better tool for the in-vivo study of HSC.
