Fig. 17, 93W5540, Ovary, Corpus Luteum, H&E
A portion of a formed corpus luteum is shown here. Most endocrine
cells are the granulosa lutein cells (GLC). These form a folded cell
mass that surrounds the remains of the former follicular cavity.
External to the corpus luteum is the connective tissue (CT) of the
ovary. Keep in mind that the theca interna was derived from the
connective tissue stroma of the ovary. The location of theca lutein
cells (TLC) reflects this origin adjacent to the surrounding
connective tissue.
