This review discusses recent discoveries about the role of Eda and other TNF-related cytokines in skin appendage development and reports no new experimental results, highlighting developments since the last comprehensive summary in 2003.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

This review discusses the multifactorial origins and pathophysiology of PCOS and highlights the effectiveness of lifestyle modifications as a first-line intervention, reporting no new research results.

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 senescence–stemness connection in cellular biology and reports no new findings, highlighting implications for both tissue repair and aggressive cancer behavior.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This review indicates that most studies reported positive effects of platelet-rich plasma injections for treating androgenic alopecia, with no major side effects, suggesting it may be a safe alternative to Minoxidil and Finasteride.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

In this study, polymeric micelles containing retinoic acid were found to improve targeted delivery to hair follicle structures in human skin more efficiently than a marketed retinoic acid gel, suggesting potentially safer and more effective acne treatment.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This study found that discontinuing finasteride led to a significant increase in sperm counts for most men with reduced fertility, though hormone levels and other semen parameters remained unchanged.

This review discusses the use of antimüllerian hormone as a marker of ovarian reserve in infertility diagnosis and treatment, noting it reflects oocyte quantity but not health or pregnancy likelihood.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

This study identified the location of the genetic locus for the slick hair coat trait in cattle on bovine chromosome 20, which may contribute to heat tolerance.

This study found that miRNA expression profiles in follicular fluid are altered in women with PCOS, with certain miRNAs potentially useful for distinguishing patient subtypes and contributing to understanding PCOS heterogeneity.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

This review discusses the International Evidence-Based PCOS Guidelines, which aim to improve diagnosis and management of PCOS and its associated comorbidities, noting the importance of early intervention and healthy lifestyle changes; it reports no new results.

This study found that the signaling peptide CLE40 and receptor proteins CLV2 and CRN regulate root meristem differentiation through two distinct, antagonistic pathways activated by CLE40 in a dose-dependent manner.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study found that melatonin significantly improved metabolic and reproductive parameters in PCOS-induced rats, with effects similar to metformin.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.
