DOI: 10.1002/jbio.201960038
Abstract: Unfertilised eggs (oocytes) release chemical biomarkers into the medium surrounding them. This provides an opportunity to monitor cell health and development during assisted reproductive processes if detected in a non-invasive manner. Here we report the… read more here.

DOI: 10.1002/jcb.27380
Abstract: The outcome of in vitro maturation (IVM) in the patients with polycystic ovary syndrome (PCOS) is poor. Abnormal intraovarian paracrine interplay alters microenvironment for oocyte development through folliculogenesis and decreases developmental competence of oocytes in… read more here.

DOI: 10.1002/mrd.22756
Abstract: Growth factors synthesized by ovarian somatic cells affect cumulus cell expansion and oocyte maturation in vitro. Fibroblast growth factor 10 (FGF10), for example, is a known regulator of mammalian cumulus‐oocyte complex maturation. In this study,… read more here.

DOI: 10.1002/tox.22384
Abstract: Malathion is one of the most commonly used insecticides. Recent findings have demonstrated that it induces oxidative stress in somatic cells, but there are not enough studies that have demonstrated this effect in germ cells.… read more here.

DOI: 10.1007/s11302-020-09690-6
Abstract: The improvement of cryopreserved oocyte survival is imperative for the preservation of female fertility. In this study, we investigate whether P2Y2 receptors (P2Y2R) can be directly implicated in calcium (Ca 2+ ) homeostasis misbalances observed… read more here.
