摘要：
EWS::FLI1 expression in human embryonic mesenchymal stem cells (heMSCs) leads to a distinct transcriptional profile associated with Ewing sarcoma, demonstrating the oncogene's role in tumorigenesis. The study reveals that EWS::FLI1 is crucial for inducing an aberrant differentiation program and defective DNA damage repair, resulting in tumor formation in vivo. This research provides insights into the cellular origins of Ewing sarcoma and highlights the potential for early-stage investment in related therapeutic strategies.
