This study suggests that age-related regenerative decline in hair follicles may be due to an imbalance of signals affecting stem cell activation, with follistatin potentially promoting renewal.

This review discusses environmental reprogramming and the plasticity of epithelial cells, emphasizing their potential for new cell therapy approaches; it reports no new experimental results.

This article reviews mammalian skin epidermis as a model for studying stem cell regulation, noting the utility of in vitro and ex vivo platforms, but it reports no new empirical findings.

This case report describes a patient who developed localized hypertrichosis of the pinnae after undergoing orchiectomy and chemotherapy for testicular carcinoma.

Hormones cause hair loss by affecting cell growth and weakening cell attraction.

This review discusses the role of dermal papilla cells in hair follicle morphogenesis and regeneration and reports no new results; the authors emphasize the importance of these cells in hair growth and pigmentation regulation.

This study found that among patients with sex cord stromal ovarian tumors, 11% exhibited signs of virilization, requiring thorough clinical evaluation to rule out non-neoplastic causes.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

The document concludes that individualized treatment and lifestyle changes are important for managing menopause symptoms and health risks.

In this study, researchers found that pregnant mice exposed to excessive androgen led to thinner ventricular walls and cardiac hypertrophy in offspring, suggesting that prenatal androgen exposure adversely affects cardiac health through reduced cardiomyocyte proliferation.

This study used single-cell ATAC sequencing to map chromatin accessibility in developing mouse hair follicles, offering insights into the transcriptional regulation and epigenetic mechanisms underlying hair follicle development.

This study found that the topical application of a mixture of Platycladus orientalis leaf extract and α-terpineol promoted hair growth in mice by inducing early anagen transition and increasing growth factor expressions.

This study found that in female breast cancer patients, supplementation with 400 mg IND02 (Cinnamon bark extract) thrice daily during chemotherapy significantly reduced severe weight loss and hair loss compared to placebo, with the treatment being well-tolerated and safe.

The researchers reported that finasteride treatment in male rats may lead to changes in antioxidant enzyme activity in their offspring's epididymis, potentially affecting sperm maturation.

This review discusses the potential of dental tissues as an alternative source of adult stem cells for regenerative medicine but reports no new experimental results, emphasizing the need for effective preservation methods.

This review discusses molecular testing for endocrine diseases, highlighting its diagnostic benefits and potential for prevention, particularly in conditions like multiple endocrine neoplasia type 2 and adrenogenital syndrome, but reports no new clinical results.

This study observed that thyroid and hormone treatments did not resolve postpartum alopecia in a small patient group, and most cases may naturally revert to normal.

This review highlights REV7's crucial roles in maintaining genome stability, its implication in several cancers, and its association with poor prognoses and treatment resistance, while also noting that REV7 suppression may improve chemotherapy sensitivity.

This study highlights the historical and contemporary use of hair sutures in plastic surgery, noting their advantages such as favorable aesthetic outcomes, minimal tissue reaction, and cost-effectiveness, despite modern synthetic alternatives.

This source reviews various herbal remedies for treating hair loss, highlighting their potential benefits and reduced side effects compared to synthetic treatments, which often do not deliver lasting results and can cause adverse reactions.

This report describes a rare case of pili multigemini, where multiple hair shafts arise from a single follicle, discovered during an examination for folliculitis on a patient's abdomen.

In a laboratory setting, this study found that overexpression of the FGF5 short form in cultured keratinocytes increased hepatic growth factor gene expression, suggesting a potential role in hair growth.

This article discusses the role of dermal papilla and dermal sheath cells in the hair cycle and reviews finasteride and minoxidil's mechanisms in promoting hair growth, but presents no new clinical findings.

This research describes methods to activate melanocyte stem cells during hair follicle regeneration and to isolate melanocytes from neonatal mouse skin, with the aim of studying melanogenesis for potential clinical applications.

This chapter reviews classic regeneration models in planarian worms and amphibian limbs, focusing on the role of stem cells, and reports no new experimental results.

This case report presented a 52-year-old man with cutaneous focal mucinosis, exhibiting rare follicular induction of the epidermis, underscoring the importance of recognizing this association in differential diagnoses.

This case report describes a middle-aged man with a growing scrotal mass, diagnosed as a benign proliferating trichilemmal tumor, which can mimic squamous cell carcinoma, highlighting the importance of correct diagnosis.

This study reports the first case of ovarian mature cystic teratoma linked to clinical virilization due to ectopic testosterone production, possibly from overexpression of the enzyme HSD17B5.
