High-Risk Rhabdomyosarcomas Feature a Convergent Cell State.

High-risk rhabdomyosarcomas share a common neural-like cell state, regardless of FOXO1 fusion status, revealing a convergent transcriptional phenotype in lethal cases.

• Why it matters: Understanding the cellular basis of high-risk disease can improve prognostic accuracy and guide targeted therapies, addressing gaps in current molecular classifications and treatment strategies.
• What they did: The study analyzed single-cell transcriptomics, chromatin accessibility, spatial transcriptomics, and perturbation data from rhabdomyosarcoma samples, identifying a shared high-risk cell state across cases.
• The result: This convergent cell state, partly independent of fusion status and featuring neural traits, offers a new framework for disease classification and potential avenues for targeted intervention.
