Characterization of the DTG scaffolds. Gross appearance of DTG scaffolds (a). H&E staining revealed the massive blue-stained cell nucleus in native thyroid gland tissues (b) and no visible cell nucleus in DTG scaffolds (c). DAPI staining revealed the existence of blue-stained nuclei in native thyroid gland tissues (d) but not DTG scaffolds (e). Scale bar = 50 µm
