“…Oocyte-follicular cell interactions are complicated events in vertebrate folliculogenesis and oogenesis, and ultimately lead to the acquisition of their respective competences through their mutual interactions (Cecconi et al, 2004;Gilchrist et al, 2004;Rolaki et al, 2005). De La Fuente and Eppig (2001) have demonstrated that mouse granulosa cells allow the transfer of about 85% of the oocyte metabolic needs and modulate oocyte transcriptional activity.…”

“…Specialized granulosa cells called cumulus cells that have surrounded the oocyte since the antral follicle stage expand and secrete hyaluronic acid following the LH surge. Prior to the LH surge, the oocyte and cumulus cells are coupled by transzonal processes and communicate through gap junction and paracrine signaling [26]. The bidirectional communication that exists between the somatic cumulus cells and the oocyte [27,28] and the metabolic support from the cumulus cells [29,30] are both essential for oocyte viability and developmental competence.…”

Obesity in women is a concern in many countries. This causes numerous health issues; however, this review focuses on the impact of obesity on women's reproduction, and in particular the oocyte. Data from infertility clinics and experimental animal models that address the effects of obesity are presented. Bidirectional communication and metabolic support from the surrounding cumulus cells are critical for oocyte development, and the impact of obesity on these cells is also addressed. Both oocyte maturation and metabolism are impaired due to obesity, negatively impacting further development. In addition to reproductive hormones, obesity induced elevations in insulin, glucose, or free fatty acids, and changes in adipokines appear to impact the developmental competence of the oocyte. The data indicate that any one of these hormones or metabolites can impair oocyte developmental competence in vivo, and the combination of all of these factors and their interactions are the subject of ongoing investigations.

“…Recently, communications and interactions between the oocyte and the surrounding follicular cells have received attention (Amleh and Dean, 2002;Matzuk et al, 2002;Gilchrist et al, 2004;Hunter et al, 2005). Although their assembly processes and corresponding interactions are strikingly similar in diverse organisms, the underlying molecular mechanisms remain enigmatic as commented by Matova and Cooley (2001).…”

“…It has become increasingly clear that the oocyte is a pivotal regulator of folliculogenesis, and an important bi-directional communication axis exists between the oocyte and somatic cells (Eppig, 2001;Eppig et al, 2002;Matzuk et al, 2002). Also, some oocyte-secreted factors play vital roles in regulating follicular cell functions and maintaining the cumulus cell phenotype (Gilchrist et al, 2004). However, the companion somatic cells were suggested to exert significant roles in regulating oocyte growth and meiotic maturation (Buccione et al, 1990), but only a few of the interactive factors were identified in mice (Veitch et al, 2004).…”
