This study found that OCT4-overexpressing human hair follicle mesenchymal stem cells show promise for artificial hematopoiesis by enhancing self-renewal through cytoskeletal remodeling and the beta-catenin-dependent adherens junction pathway.

This study found that in mice with premature ovarian insufficiency, miR-21 enhances ovarian function recovery following umbilical cord-derived mesenchymal stem cell transplantation by influencing specific cellular signaling and immune pathways.

This study in a transgenic mouse model found that repressing overexpression of ornithine decarboxylase reduced papilloma development, indicating its role in tumor promotion sensitivity.

This study concludes that age has a substantial impact on live birth rates in IVF, more so than BMI, while cumulative live birth rate is the most informative measure of reproductive success.

This study found that ornithine decarboxylase expression is linked to cell proliferation and differentiation in hair follicle development and growth.

This case report details a woman with autoimmune primary ovarian insufficiency linked to hormonal contraception discontinuation, who achieved pregnancy through ovarian stimulation and in vitro fertilization despite typically low fertility in such conditions.

This study found that CD45RO+ cells, a subtype of T lymphocytes, were notably reduced in the ovarian follicles of women with PCOS, which may contribute to the condition's pathogenesis.

This review discusses the diagnostic challenges of PCOS in adolescents, noting that the persistence of hyperandrogenism and oligomenorrhea is required for diagnosis, while genetic studies suggest involvement of the hypothalamic-pituitary-ovarian axis.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This study found that umbilical cord-derived CD146+ MSCs showed a stronger ability to improve ovarian function and modulate immune responses in a mouse model of premature ovarian failure compared to CD146- MSCs, though both subpopulations effectively repaired reproductive ability.

This study suggests that supplementing with a cell-free fat extract might enhance embryo development and improve clinical outcomes in older women experiencing in vitro fertilization failure.

This case series highlights that diagnosing ovarian Leydig cell tumors can be challenging, and expert sonography is crucial for accurate identification, as imaging modalities like CT, MRI, and PET-CT may fail to detect them.

Transplanted human Olig2+ astroglia may help improve learning and memory after a stroke.

In this study, embryonic skin fibroblasts from day E17.5 and postnatal day P5, but not E14.5, effectively supported hair follicle formation, indicating distinct developmental states and differentiation capacities.

In this study, researchers characterized the retinal structure and function of the Oat^rhg mouse model of gyrate atrophy, finding localized atrophy without significant retina-wide functional impact, suggesting the model may be useful for testing new treatments using multimodal retinal imaging.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study demonstrates that the ability of human hair follicle keratinocytes to form clones decreases with ageing.

This study found that the Ovol2-Zeb1 regulatory circuit is crucial for controlling directional migration and proliferation in epithelial cells, facilitating skin regeneration and repair in mice.

This study found that HDAC6 plays a crucial role in regulating primordial follicle activation, with its overexpression delaying activation and preserving fertility by reducing NGF levels.

In this retrospective cohort study, no significant differences were observed in assisted reproductive outcomes among different PCOS phenotypes undergoing frozen-thawed embryo transfer.

This study integrated single-cell RNA-seq data from four previous studies to create a comprehensive human corneal cell state meta-atlas, revealing novel marker genes, rare cell states, and distinct transcription factors, and offering a tool to enhance future cornea research.

This article suggests using only firm criteria to diagnose polycystic ovary syndrome in adolescents, due to the evolving nature of its features during this period.

This review highlights the roles of key transcription factors and signaling pathways in regulating olfactory epithelium regeneration, discussing recent advances in single-cell and spatial transcriptomics as well as organoid models to enhance understanding of olfactory regeneration mechanisms.

In this study, researchers characterized the clinical features of ophiasis, an uncommon type of alopecia areata, and proposed a new subtype classification that may help predict treatment response and guide management, noting that ophiasis generally has a chronic and refractory nature.

This study reported that overexpressing ornithine decarboxylase in C57Bl/6 mice increased their sensitivity to tumor promotion by TPA, a change reversible by doxycycline treatment.

This dissertation reported that the loss of Ovol2 impairs hair follicle regeneration and wound repair in mice, highlighting its role in regulating directional migration of epithelial cells.

This study demonstrated that the tracheal xenotransplant procedure is an effective technique for assessing the invasiveness of epidermal keratinocytes and studying factors affecting hair follicle formation.

In this study, researchers found that mice lacking the transcription factor FOXC1 in their hair follicle stem cells had increased rounds of hair regeneration but experienced hair thinning due to impaired ability to maintain stem cell quiescence and adhesion.
