In Vitro Gamete Production in Mammals: Decades of Pioneering Approaches in Germ Cell and Stem Cell Biology Supporting Innovative Discovery and Expansion of Human Reproductive Potential

open access: yesMolecular Reproduction and Development, Volume 92, Issue 12, December 2025.
ABSTRACT During recent decades a myriad of approaches have emerged for generating surrogate gametes or achieving in vitro gametogenesis (IVG). The most recent approaches to IVG include the development of increasingly complex culture systems, use of companion cells combined with germ line cells in two‐ or three‐dimensional configurations, derivation of ...

Development of Mouse Preantral Follicle after In Vitro Culture in A Medium Containing Melatonin [PDF]

open access: yesCell Journal, 2015
Objective: Improvements in cancer treatment have allowed more young women to survive. However, many cancer patients suffer from ovarian failure. Cryopreservation is one of the solutions for fertility restoration in these patients. The cryopreservation of

Calcium alginate microencapsulation of ovarian follicles impacts FSH delivery and follicle morphology [PDF]

open access: yes, 2005
Background We have previously shown that suspension culture prevents follicle flattening and maintains three-dimensional follicle architecture better than culture on flat plates. However, many of the follicles cultured in suspension do eventually rupture,

Immunohistochemical localization of proliferating cell nuclear antigen (PCNA) in the pig ovary.

open access: yesFolia Histochemica et Cytobiologica, 2007
The aim of the study was to determine the expression of proliferating cell nuclear antigen protein (PCNA) in the pig ovary. The localization of PCNA was demonstrated in paraffin sections of pig ovarian tissue using primary mouse monoclonal anti-PCNA ...

Effect of Phoenix dactylifera pollen grain on maturation of preantral follicles in NMRI mice [PDF]

open access: yes, 2015
Introduction: Optimizing an ideal culture system that is comparable to follicle environment to obtain mature oocytes is one of the important criteria in in vitro maturation (IVM). Phoenix dactylifera L. commonly known as date palm is an important herb in

Follicular size affects the meiotic competence of in vitro matured prepubertal and adult oocytes in sheep [PDF]

open access: yes, 1999
Non-atretic follicles dissected from prepubertal and adult ovaries were allocated in three groups: a) < 1 mm; b) 1-2 mm; c) > 2 mm. After 24 h of maturation, a lower percentage of adult oocytes from group a (P < 0.01) reached metaphase II than ...

Annexin II mRNA expression in bovine oocytes during follicular development

open access: yesGenetics and Molecular Biology, 2006
We investigated the expression of calcium-dependent phospholipid binding protein annexin-II (Ann-II) messenger RNA (mRNA) during preantral follicle development and in oocytes from antral follicles of different diameters (< 3 mm, 5 to 8 mm and > 8 mm ...
