It features remarkable cellular heterogeneity. Using single-cell RNA sequencing, we characterize the cellular composition of the OCS and identify their molecular characteristics.\u0000Methods\u0000\u0000we applied single-cell RNA sequencing (scRNA-seq) to resected primary OCS for the in-depth analysis of tumor cells and the TME. Immunohistochemistry (IHC) staining was used for validation.\u0000Results\u0000\u0000Malignant epithelial and fibroblast cells displayed a high-degree of intratumoral heterogeneity. We revealed that certain epithelial cell subclusters had high levels of drug resistance scores and many active metabolic pathways. Furthermore, γδ T cells exhibited enriched IFNγ and IFNα response characteristics. Notably, we observed that macrophages were mainly M2-like macrophages with immunosuppressive properties. In addition, we found that the CD1A+/FCER1A+ DC cells were enriched with genes related to cytolytic effector pathway. Analyzing ligand-receptor interaction pairs between cell types, we identified broadly interacting cells and observed an interaction between the ANXA1+ epithelial population and FPR1+/FPR3+ myeloid cells.\u0000Conclusion\u0000\u0000Our findings provide a comprehensive single-cell transcriptomic landscape of human OCS and present a well-established resource for elucidating OCS diversity.","PeriodicalId":192166,"journal":{"name":"Proceedings of the ASGO 2022 7th International Workshop","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126858234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
