    Single-Cell Architecture and Functional Requirement of Alternative Splicing during Hematopoietic Stem Cell Formation

    Investigators used single-cell full-length transcriptome data to construct an isoform-based transcriptional atlas of the murine endothelial-to-HSC transition, which enabled the identification of hemogenic signature isoforms and stage-specific alternative splicing events.
