we now demonstrate that the grp gene is expressed in human thyroidal calcitonin ( ct ) -containing neuroendocrine cells ( c-cells ) in an ontogenic pattern similar to its expression in pulmonary neuroendocrine cells and is also expressed at high levels in c-cell hyperplasias and neoplasias ( medullary carcinomas of the thyroid ) .
