Teratoma assay
WebA teratoma is a type of germ cell tumor (a tumor that starts in your reproductive cells). Teratomas can contain many different types of tissue, including bone, muscle, teeth and … Pluripotent stem cells including human induced pluripotent stem cells have a unique property of being able to generate teratomas when injected in rodents in the research laboratory. For this reason, the so-called "teratoma assay" is one of the gold-standard validation assays for pluripotent stem cells. Because differentiated human pluripotent stem cells are being developed as the basis for numerous regenerative medicine therapies, there is concern that residual undiff…

WebTeratoma at orchiectomy was the only predictor of PC-RPLND teratoma. Small RNA sequencing identified three potentially discriminatory miRNAs, but further validation demonstrated no utility. Our results confirm prior reports that serum miR-375 cannot predict teratoma, and suggest that there may not exist a predictive serum miRNA for teratoma. WebAug 20, 2024 · As teratomas contain all three germ layers (endoderm, mesoderm, ectoderm), teratoma formation assay is widely used as an index of pluripotency (Evans …
