Single‐Cell RNA Sequencing Reveals the Heterogeneity in Differentiation Trajectory and Tumor Microenvironment Leading to More Aggressive Phenotypes of Papillary Thyroid Cancer in Children and Young Adult Patients

Abstract excerpt

The tumor ecosystem heterogeneity of papillary thyroid carcinoma (PTC) is poorly characterized in children and young adult patients (CAYA-PTC). In this study, single-cell RNA sequencing is used to profile transcriptomes from the paratumor and tumor tissues of 11 patients. Compared to adult, CD4T_Tfh and CD8T_Tex cells are significantly more prevalent in CAYA-PTC patients. Three phenotypes are identified within...
