Single-cell analysis reveals five distinct tumor microenvironment ecotypes in multiple myeloma, with one linked to tumor expansion and poor clinical outcomes.
- Why it matters: Understanding how the tumor microenvironment evolves across disease stages is crucial for addressing immune dysregulation and therapeutic resistance in multiple myeloma.
- What they did: Researchers integrated single-cell RNA and receptor sequencing data from 235 bone marrow samples, identifying five reproducible TME ecotypes characterized by cellular architecture and communication networks.
- The result: The ecotype enriched for bone marrow-resident cells and limited immune infiltration correlates with tumor growth and worse outcomes, providing a framework for stage-specific immunotherapy strategies.
