Does lithium inhibit palatal fusion and osteogenic differentiation in palatal shelves in vitro?
Our findings show that LiCl-mediated GSK3β inhibition prevents palatal fusion and osteogenic differentiation in palatal shelves by increased β-catenin signaling. It indicated that overactivation of canonical Wnt signaling might impair the fusion of the secondary palate.
Intraoperative FS was most helpful when the FNA findings were suspicious for malignant disease. FS does not seem to be necessary when FNA indicates malignant or benign disease. Both FNA and FS failed to detect occult thyroid carcinomas.
