Oogenesis in cultures derived from adult human ovaries

Reproductive Biology and Endocrinology, 2005
Ten years ago, we reported that in adult human females the ovarian surface epithelium (OSE) is a source of germ cells. Recently, we also demonstrated that new primary follicles are formed by assembly of oocytes with nests of primitive granulosa cells in ...

Ovarian pain in the mare: Clinical implications of mittelschmerz and oestrus‐related behavioural abnormalities

Equine Veterinary Education, Volume 38, Issue 12, Page 661-667, December 2026.
Summary Mittelschmerz is a well‐recognised benign peri‐ovulatory pain syndrome in women and, by physiological analogy, may also occur in mares. In equine practice, peri‐ovulatory ovarian pain has been associated with transient discomfort, colic‐like signs and behavioural changes, although its true clinical relevance remains poorly defined.

Swine granulosa cells show typical endothelial cell characteristics

, 2016
. Granulosa cells, which belong to the somatic compartment of the ovarian follicle, are actively involved as endocrine cells in follicle growth. Recently, it has been proposed that these cells are not terminally differentiated and possess multipotency ...

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, Volume 13, Issue 61, 3 November 2026.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

The utility of serum markers in the conservative management of placenta accreta spectrum (PAS) by leaving the placenta in situ in women with high‐grade PAS

International Journal of Gynecology &Obstetrics, Volume 175, Issue 2, Page 895-901, November 2026.
Abstract Objective To investigate the association between serum markers and successful conservative management of patients with placenta accreta spectrum (PAS). Methods This was a retrospective case–control study where patients with high‐grade PAS between 2011 and 2025 undergoing conservative leaving the placenta in situ were included.

Cycloastragenol Attenuates Cisplatin‐Induced Ovarian Toxicity in Rats: Associations With TERT Expression, Apoptotic Balance, and FOXO3a–mTOR‐Related Signaling

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
Cycloastragenol partially attenuated cisplatin‐induced ovarian toxicity and was associated with partial preservation of follicular morphology, improvement in apoptotic balance, and changes in FOXO3a–mTOR‐related markers and ovarian TERT expression. ABSTRACT Cisplatin (CIS)‐induced ovarian toxicity is characterized by follicular depletion, apoptosis ...

Ovarian granulosa cell tumors : histopathology, immunopathology and prognosis

, 1987
Granulosa cell tumors (GCT) of the ovary account for 2% of all ovarian tumors. As the name indicates, they are composed of granulosa cells but may also contain an admixture of theca cells.

hAECs restore follicular development in premature ovarian insufficiency via IGFBP2/IGF1R-mediated intercellular communication

Stem Cell Research & Therapy
Background Premature ovarian insufficiency (POI) is defined by ovarian dysfunction and consequent decreased fertility. While follicular depletion is an acknowledged factor, dynamic changes in follicular subpopulations and single-cell-level niche ...

Ultrasonography (IOTA‐ADNEX) vs magnetic resonance imaging (ADNEX MR) for diagnosing ovarian cancer in high‐risk patients: a prospective study

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 5, Page 701-713, November 2026.
ABSTRACT ObjectivesTo systematically validate and compare ultrasonography, using the ultrasound‐based International Ovarian Tumor Analysis – Assessment of Different NEoplasias in the adneXa (IOTA‐ADNEX) model, with magnetic resonance imaging (MRI), using the MRI‐based ADNEX MR scoring system, as second‐line imaging modalities for estimating the risk of

In vitro characterization of granulosa progenitor cells isolated from bovine ovarian follicl

, 2014
Ovarian granulosa is a highly available cell cluster that could be used as an alternative source of mesenchymal stem cells (MSCs) for veterinary medicine applications. To this, presumptive granulosa MSCs (gMSCs) were isolated by aspirating the follicular
