    Image of C cell hyperplasia in the thyroid gland from a female F344/N rat in a chronic study
    Thyroid gland, C cell - Hyperplasia in a treated female F344 rat from a chronic study. Aggregates and small nests of C cells have replaced follicles in this thyroid gland.

    Thyroid gland, C cell - Hyperplasia in a treated female F344 rat from a chronic study. Higher magnification of Figure 1 shows the contiguous nests of C cells surrounding small follicles.
    Image of C cell hyperplasia in the thyroid gland from a male F344/N rat in a chronic study
    Thyroid gland, C cell - Hyperplasia in a control male F344 rat from a chronic study. A focal proliferation of C cells is present in this thyroid gland (arrow).
