Differentiation of definitive thyroid endoderm from human iPSCs (LF cells). (A) qPCR analysis of thyroid transcriptional factors NKX2-1 and PAX8 in human ES cells and human iPSCs (LF cells). Fold change is represented as the mean ± SEM of three independent experiments. (B) Immunostaining of NKX2-1 (Red) and PAX8 (Green) in human iPSCs (LF cells) derived thyroid endoderm cells. Scale bar = 20 μm. (C) Representative flow cytometry of NKX2-1 and PAX8 expressing cells in untreated (upper), activin A treated (middle) and activing A + Ethacridine (lower) cells. Data were representative of three separate experiments.
