n.
An epithelial cell lining a follicle, such as that of the thyroid or ovary.

(fŏ-lik'yū-lăr sel)
An epithelial cell lining a follicle, such as that of the thyroid or ovary.

follicular cell

1. The secretory cell of the thyroid gland; it produces the thyroid hormones, T3 (triiodothyronine) and T4 (tetraiodothyronine or thyroxine).
2. Any of the flattened somatic cells that form a monolayer around each primary oocyte in the ovary. After puberty, when an oocyte matures, during a monthly cycle, its follicular cells divide, become cuboidal, and form a multilayered coating for the oocyte; at this stage, the follicular cells are called granulosa cells.
