Cancer-associated fibroblasts (CAFs) and partial epithelial-mesenchymal transition (p-EMT) tumor cells are closed together and contribute to the tumor progression of oral squamous cell carcinoma (OSCC). In the present study, we deeply analyzed and integrated OSCC single-cell RNA sequencing datasets to define OSCC CAFs and p-EMT subpopulations. We highlighted the cell-cell interaction network of CAFs and p-EMT tumor cells and suggested biomarkers for the diagnosis and prognosis of OSCC during the metastasis condition. The analysis discovered four subtypes of CAFs: one p-EMT tumor cell population, and cycling tumor cells as well as TNFSF12-TNFRSF25/TNFRSF12A interactions between CAFs and p-EMT tumor cells during tumor metastasis. This suggests the prediction of therapeutically targetable checkpoint receptor-ligand interactions between CAFs and p-EMT tumor cells in OSCC regarding the metastasis status.
癌症相关成纤维细胞 (CAFs) 和部分上皮-间充质转化 (p-EMT) 肿瘤细胞紧密相连，共同促进口腔鳞状细胞癌 (OSCC) 的肿瘤进展。在本研究中，我们深入分析和整合了 OSCC 单细胞 RNA 测序数据集，以定义 OSCC CAFs 和 p-EMT 亚群。我们强调了 CAFs 和 p-EMT 肿瘤细胞的细胞-细胞相互作用网络，并提出了在转移条件下用于 OSCC 诊断和预后的生物标志物。分析发现了四种 CAFs 亚型：一个 p-EMT 肿瘤细胞群体，以及循环肿瘤细胞和 TNFSF12-TNFRSF25/TNFRSF12A 之间的相互作用 CAFs 和 p-EMT 肿瘤细胞在肿瘤转移过程中。这表明可以预测 OSCC 中 CAFs 和 p-EMT 肿瘤细胞之间在转移状态下具有治疗潜力的检查点受体-配体相互作用。
