Abstract
Thyroid carcinoma represents the first malignancy among the endocrine organs. Investigating the cellular hierarchy and the mechanisms underlying the initiation of thyroid carcinoma is crucial in thyroid cancer research. Here, we present a protocol for deriving thyroid cell lineage from human embryonic stem cells. We also describe steps for engineering thyroid progenitor cells utilizing CRISPR-Cas9 technology, which can be used to perform in vivo studies, thus facilitating the development of representative thyroid tumorigenesis models. For complete details on the use and execution of this protocol, please refer to Veschi et al.1.
