Paternal Sperm Gnas‐ICR Epigenetic Programming Contributes to PPP‐Like Phenotypes in Female Offspring

Advanced Science, EarlyView.
A paternal glucocorticoid–sperm Gnas‐ICR axis is linked to ovarian endocrine programming in female offspring. Paternal preconception caffeine exposure elevates corticosterone, promotes sperm Gnas‐ICR hypermethylation, and is associated with ovarian Gnas upregulation, cAMP/PKA/CREB–StAR activation, enhanced estradiol synthesis, and PPP‐like phenotypes ...

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

Advanced Science, EarlyView.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

Post-warming quality of goat oocytes under heat shock stress: A study of the maturation rate, heat shock protein-70, adenosine triphosphate, and glutathione levels [PDF]

Veterinary World
Background and Aim: Indonesia’s indigenous Kacang goat population is in decline, posing a threat to food security and genetic diversity. In vitro maturation and cryopreservation techniques are key strategies for genetic conservation.

Optimization of In Vitro Maturation in Ovine Oocytes: A Comparative Study of Maturation Media

Gene Cell and Tissue
Background: One of the most common techniques in assisted reproductive technologies (ART) is in vitro embryo production (IVEP), the success of which depends on the intrinsic quality of oocytes and the composition of the culture medium.

Establishment of Interspecies Somatic Cell Nuclear Transfer and Transgene‐Free Inducible Pluripotent Stem Cells for Versatile Conservation of the Germplasm Resource of Wild Boar

Animal Research and One Health, EarlyView.
Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

Effect of different activation techniques on immature and in Vitro matured cat oocytes

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2014
This study was conducted to determine the most successful techniques on inmature and in vitro-matured cat oocytes that were parhtenogenically activated using 6-dimethylaminopurine (6-DMAP) and cycloheximide (CHX), in combination with electrical stimulation and calcium ionophore.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
