[Research Progress of Single-cell Transcriptome Sequencing Technology in Physiological Hematopoiesis--Review]

Area of Science:

• Developmental Biology
• Hematology
• Genomics

Background:

• Hematopoiesis is a lifelong, intricate process originating in the embryo, involving multiple anatomical sites like the yolk sac, fetal liver, and bone marrow.
• Early research utilized flow cytometry and animal models to study hematopoietic cell differentiation, but faced limitations in tracking single-cell activity.
• Understanding hematopoietic development is crucial for diagnosing and treating hematological malignancies.

Approach:

• This review focuses on the application of large-scale single-cell transcriptome sequencing in physiological hematopoiesis research.
• Single-cell transcriptomics enables detailed mapping of cell fate transitions during hematopoietic development.
• This technology overcomes previous technical limitations in tracking individual cell activities within hematopoietic organs.

Key Points:

• Single-cell transcriptome sequencing provides an unprecedented view of hematopoietic cell differentiation pathways.
• It allows for the creation of highly detailed cell fate transition maps.
• Advances in this technology offer new avenues for diagnosing and treating hematological tumors.

Conclusions:

• Single-cell transcriptome sequencing is revolutionizing the study of hematopoiesis.
• This approach provides a powerful tool for understanding normal blood formation and its dysregulation in disease.
• Future research will likely leverage these techniques for improved diagnostics and therapeutics in hematology.
