Description
The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle and is responsible for the decidualization of the endometrium. The Immortalized Rat Luteal Cells (GG-CL) is conditionally immortalized through the temperature-sensitive simian virus (SV40 tsA209) and has retained many primary luteal cell markers such as estrogen receptor-β, glucocorticoid receptor (GR), interleukin-6 (IL-6), orphan nuclear receptor nur 77 and 20α-hydroxysteroid dehydrogenase (20α-HSD). In addition, GG-CL responds to stimulation by PRL, estradiol, and cAMP, making the cells a useful model for studies involving gene expression and regulation of luteal cells
