Figure 2. Kisspeptin (KP) Expression in the Ovary Mainly Occurs in the Granulosa Cells (GC) in Response to Preovulatory LH Surge.

Figure 2.

LH surge also induces the expression of the full length NTRK2 receptor, which with kisspeptin signaling drives oocyte survival through the PI3K/AKT pathway. In addition, kisspeptin stimulates steroid secretion by theca (TC) and luteal cells (LC).
