Single-cell lineage tracing approaches in hematology research: technical considerations

Area of Science:

• Hematology
• Stem Cell Biology
• Immunology

Background:

• Hematopoietic stem and progenitor cells (HSPCs) differentiate into mature blood cells, maintaining immune and blood homeostasis.
• Cell fate decisions in hematopoiesis occur at the single-cell level.
• Understanding these processes is crucial for both health and disease states.

Purpose of the Study:

• To review essential single-cell clonal assays for studying hematopoiesis.
• To discuss methodologies and technical considerations for these assays.
• To synthesize recent advancements presented at ISEH meetings.

Main Methods:

• Single-cell transplantation assays.
• Lentiviral barcoding techniques.
• Sleeping Beauty barcoding methods.

Main Results:

• Clonal assays are vital for tracing single-cell fates in hematopoiesis.
• These methods have significantly advanced our understanding of blood cell development.
• The review synthesizes current knowledge and technical considerations.

Conclusions:

• Single-cell clonal assays are indispensable tools in experimental hematology.
• Continued development and application of these methods will further elucidate hematopoietic processes.
• This work provides a foundation for researchers new to these technologies.
