In vivo thyroid functionality assessment in adult Fgf10 Ex1mut/Ex3mut chimeric mice complemented with mouse embryonic stem cells (mESCs). (A) Immunofluorescence staining of the thyroids. Thyroid follicles were analyzed by staining for GFP (green) and markers of thyroid function. Tg, thyroglobulin; T3, tri-iodothyronine. Insets show magnified views of the areas indicated with white dotted lines. The right panels show magnified views of the areas indicated by dotted lines in the left panels. Nuclei were stained with DAPI (blue). Fgf10 wild/wild and Fgf10 Ex1wild/Ex3mut chimeric mice served as controls. Scale bar = 50 μm. (B) ELISA analyses of serum tri-iodothyronine (T3) and thyroxine (T4) concentrations in adult Fgf10 Ex1mut/Ex3mut chimeric mice. Adult Fgf10 wild/wild and Fgf10 Ex1mut or Ex3mut chimeric mice served as controls. Data are expressed as the means ± standard deviations; n = 3 for the adult Fgf10 Ex1mut/Ex3mut chimeric mouse group and n = 4 for the adult Fgf10 wild/wild and Fgf10 Ex1mut or Ex3mut chimeric mouse groups; *p > 0.05 versus other treatments.
