To evaluate the biological behavior of carcinomas in vitro, permanent tumour cell lines are required. However, previously, only a few human YST cell lines have been established. Therefore, we aimed to establish a novel YST cell line. Materials and Methods: We established a novel YST cell line, TC587, from an adolescent patient with ovarian YST. Results: The cell line expressed AFP and SALL4, the characteristics of YST. In addition, we evaluated somatic mutations using next-generation sequencing and revealed some pathogenic variants, including mutations in the NRAS, KIT, KMT2C, RSF1, and TP53 genes. Conclusion: The newly established TC587 cell line may represent an effective tool for developing treatments and conducting molecular analyses for YST.
