Derived from theca cells. They increase in number (hyperplasia) and contain receptors for LH. They are primarily responsible for P4 production. 4. Comparative Anatomy (Species Differences)
Involved in smooth muscle contraction (milk letdown, parturition). Derived from theca cells
Derived from granulosa cells. They increase in size (hypertrophy) and contain receptors for PGF2 . They produce P4 and Oxytocin. Derived from theca cells
