PGRMC1/2 promotes luteal vascularization and maintains the primordial follicles of mice

ABSTRACT: To determine whether conditional depletion of Progesterone Receptor Membrane Component (PGRMC) 1 and PGRMC2 affected ovarian follicle development, follicle distribution was assessed in ovaries of young (≈ 3 month-old) and middle-aged (≈6 month-old) control (Pgrmc1/2fl/fl) and double conditional PGRMC1/2 knockout (Pgrmc1/2d/d) mice. This study revealed that the distribution of primary, preantral and antral follicles was not altered in Pgrmc1/2d/d mice, regardless of the age. Although the number of primordial follicles was similar at ≈ 3 months of age, their numbers were reduced by ≈ 80% in 6-month old Pgrmc1/2d/d mice compared to age-matched Pgrmc1/2fl/fl mice. The Pgrmc1/2d/d mice were generated using Pgr-cre mice, so ablation of Pgrmc1 and Pgrmc2 in the ovary was restricted to peri-ovulat
