They help us fight infections. These types of cancers develop in the cells that line the thymus gland (epithelial cells). Thymomas and thymic carcinomas are more common in people above the age of 50.

Human peadiatric thymus image from the IBEX protein multiplex (44 proteins on the same image) platform. Thymic epithelial cells are labeled with 5 different keratin antibodies.

the thymic cells were already secreting PTH at a maximum capacity. Clearly, further studies are needed to elucidate the mechanisms that control PTH secretion in the thymus.
