New hyaluronan-based biomatrix for 3-D follicle culture yields functionally competent oocytes

Reproductive Biology and Endocrinology, 2022
Background Encapsulation of follicles within a biomatrix is one approach to maintaining 3-D follicle architecture during culture. Hyaluronan is one component of the natural extracellular matrix (ECM) that provides support to cells in vivo.

Androgen-induced exosomal miR-379-5p release determines granulosa cell fate: cellular mechanism involved in polycystic ovaries

Journal of Ovarian Research, 2023
Polycystic ovarian syndrome (PCOS) is a complex multi-factorial syndrome associated with androgen excess and anovulatory infertility. In the current study, we investigated the role of dihydrotestosterone-induced exosomal miR-379-5p release in determining

In Vitro Culture of Mouse Preantral Follicle in Supplemented Medium with Bone Morphogenetic Protein 15 (BMP15)

Otorhinolaryngology and Facial Plastic Surgery, 2021
Background: BMD-15 is a member of the superfamily of transforming growth factor-beta (TGF-β), which has a determinant role in fertility. This protein is essential for the development of ovarian follicles and acts mainly by binding to its receptor on the

Individual 17-Hydroxyprogesterone Responses to hCG Are Not Correlated With Follicle Size in Polycystic Ovary Syndrome. [PDF]

, 2019
Context:In women with polycystic ovary syndrome (PCOS), 17-hydroxyprogesterone (17-OHP) responses to gonadotropin stimulation vary from increased to indistinguishable compared with normal controls.

Ultrastructural features of agouti (Dasyprocta aguti) preantral follicles cryopreserved using dimethyl sulfoxide, ethylene glycol and propanediol [PDF]

, 2012
The objective was to develop an efficient protocol for cryopreservation of agouti (Dasyprocta aguti) ovarian tissue. Agouti ovarian fragments were placed, for 10 min, in a solution containing MEM and fetal bovine serum plus 1.5 M dimethyl sulfoxide (DMSO)

Fosl2 Regulates FSH‐Dependent Follicle Maturation Through Feedback Amplification of FSH/FSHR Signaling

Advanced Science, EarlyView.
This study identifies a FOSL2‐driven positive feedback loop that amplifies FSH/FSHR signaling. During FSH‐dependent follicle maturation, FSH induces Fosl2 expression via the cAMP‐PKA‐CREB cascade. FOSL2 in turn binds the promoters of Fshr and estrogen‐biosynthesis genes to enhance their transcription, thereby increasing Fshr mRNA level and amplifying ...

Granulosa cell-derived miR-379-5p regulates macrophage polarization in polycystic ovarian syndrome

Frontiers in Immunology, 2023
Polycystic ovarian syndrome (PCOS) is associated with hyperandrogenemia and ovarian antral follicle growth arrest. We have previously demonstrated that androgen-induced exosomal release of miR-379-5p (miR379) from preantral follicle granulosa cells ...
