Single-Cell RNA Sequencing in Hematological Diseases.

Hematological diseases, including leukemia, lymphoma, and multiple myeloma, are characterized by high heterogeneity with diverse cellular subpopulations. Single-cell RNA sequencing (scRNA-seq), a transformational technology, provides deep insights into cell-to-cell variation in tumor and microenvironment, allows high-resolution dissection of the pathogenic mechanisms of diseases, and affords potential clinical utilities. Recent developments in single-cell transcriptomics and associated technologies and their applications in hematological disorders for unraveling cellular subpopulations, disease pathogenesis, patient stratification, and therapeutic responses are summarized.
