Differential Activation of Immune Effector Processes in Mature Compared to Immature Sacrococcygeal Teratomas

Objective: This study aims to characterize the molecular signatures of sacrococcygeal teratomas (SCTs). Methods: Three SCTs were analyzed with whole genome genotyping. RNA sequencing of 10 SCTs dominated by mature, immature and neuroglial elements was analyzed. Expression in SCT-samples with different elements were compared to each other and to a reference group of malignant pediatric tumors. Macrophages, T- and B-lymphocytes were detected by...
