Ovary maturatıon stages and histological investigation of ovary of the Zebrafish (Danio rerio)
Brazilian Archives of Biology and Technology, 2008 Microscopic ovary features of Zebrafish were analyzed. Samples were fixed in Bouin’s solution, mounted in parafin and cut into 6-7 µm-thick slices which were stained with Hematoxylin and Eosin (HE), methylene blue and using Periodic-acid Schiff method ...

Advanced Science, EarlyView.Using single‐cell and spatial transcriptomics, we identified key regulators that govern cell differentiation involved in parasite development and egg laying in Schistosoma japonicum. This comprehensive study establishes a foundational resource for understanding schistosome biology, deciphers the regulatory programs underlying cell differentiation and ...

Gonadoblastoma Arising in Undifferentiated Gonadal Tissue within Dysgenetic Gonads [PDF]
The Journal of Clinical Endocrinology & Metabolism, 2006 The purpose of the study was to define the histological origin of gonadoblastomas, allowing the identification of high-risk patients.Sixty paraffin-embedded gonadectomy or gonadal biopsy samples of 43 patients with gonadal dysgenesis were selected from our archives.

Conditional strategies to study gene function during gonadal development in mammals. [PDF]
, 2008 Sexual development in mammals involves a complex cascade of genetic events. These begin with a cell fate decision, whether to make Sertoli or follicle cells, that gives rise to the development of a male or female gonad, which is controlled by the testis ...

Gonad differentiation toward ovary
, 2020 International audienceGonad differentiation depends on a set of cellular and hormonal signals interacting in a specific order, with very precise windows of action, to contribute to the establishment of the genital tract and a male or female phenotype ...

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 ...

Sex-biased miRNAs in gonad and their potential roles for testis development in yellow catfish. [PDF]
, 2014 Recently, YY super-male yellow catfish had been created by hormonal-induced sex reversal and sex-linked markers, which provides a promising research model for fish sex differentiation and gonad development, especially for testis development.

Advanced Science, EarlyView.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 ...

Gonadal Steroids and Immunity* [PDF]
Endocrine Reviews, 1996 I. Introduction THE remarkable female predominance of such diverse autoimmune diseases as systemic lupus erythematosus (SLE), Hashimoto's thyroiditis, rheumatoid arthritis, and primary biliary cirrhosis has suggested to many clinicians that hormonal differences between the sexes must confer some protective effect on males or enhance the susceptibility ...
