follicles (thyroid) Spherical structures that make up the thyroid gland; contain a gel-like colloid surrounded by a single layer of cells, which secrete thyroglobulin into the colloid.
Hair follicles are lined with cells that synthesize the proteins that form hair. A sebaceous gland (that secretes the oily coating of the hair shaft), capillary bed, nerve ending, and small muscle are associated with each hair follicle.
Hair follicles also contain stem cells, and some researchers predict research on these follicle stem cells may lead to successes in treating baldness through 'hair multiplication'/'hair cloning' within three or four years (as of Nov. 2004).
The larger follicles (Fig. 1164) consist of an external fibrovascular coat, connected with the surrounding stroma of the ovary by a net-work of bloodvessels; and an internal coat, which consists of several layers of nucleated cells, ...

A cell that is located in the spaces of a tissue, in particular, between follicles of the ovary and between seminiferous tubules of the testis. In the testes these cells produce testosterone: the male sex steroid.

Chemotherapy drugs also kill certain adult cells that divide more rapidly, such as those that line the gastrointestinal tract, bone marrow cells, and hair follicles.
