Lysophosphatidic acid increases in  vitro maturation efficiency via uPA-uPAR signaling pathway in cumulus cells

Lysophosphatidic acid (LPA) is a phospholipid-derived signaling molecule with biological activities, such as stimulating cell proliferation, differentiation and migration. In the present study, we examined the effect of LPA on porcine oocytes during in  vitro maturation (IVM) and subsequent embryonic development following parthenogenetic activation (PA) and in vitro fertilization (IVF). During IVM, the maturation medium was supplemented with various concentrations of LPA (0, 10, 30, and 60 μM). After 42 h of IVM, the 30 μM LPA-treated gr oup showed a significant (P
