High doses of finasteride cause cell growth and tumors in mice.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

This study found that women with polycystic ovary syndrome have higher serum VEGF-B levels, which are linked to insulin resistance and decrease after metformin treatment.

This review covers recent developments in materials for in vitro and in vivo stem cell manipulation, highlighting innovative substrate properties but does not report new experimental results.

In this case study, an 8-year-old female Huacaya alpaca displaying male behavior was diagnosed with an ovarian benign interstitial (Leydig) cell tumor, indicated by elevated testosterone levels.

This study found that fetal calf serum can protect Merkel cells from death and alter their morphology in culture, while serum-free conditions led to high cell mortality.

This study found that storing hair follicle micrografts in HEPES-buffered DMEM with ACD inhibitors like aminoguanidine significantly increased hair shaft elongation compared to phosphate-buffered salt solution, suggesting improved viability for transplantation.

This review discusses the potential of stem cell therapy for hair regrowth, emphasizing the advantages and promising outcomes, but reports no new clinical results.

This study found that mutations in the Sgk3 gene cause defective hair follicle development and altered hair cycling in mice, with variable phenotypic outcomes depending on different dysfunction patterns of the SGK3 protein.

This study reviews the structural and functional aspects of cell-cell and cell-matrix junctions in sebocytes, emphasizing their roles in sebocyte differentiation and sebum secretion, and how these processes may change in pathological conditions, potentially providing insights for new skin disease therapies.

This study found that diffusion coefficients of chemicals in artificial sebum are significantly higher than those in stratum corneum lipids, suggesting the hair follicle may significantly contribute to transdermal permeation.

This study describes optimized methods for culturing hair cells from 4-day-old C3H mice, leading to successful maintenance of hair-specific cytoskeletal protein expression under the experimental conditions.

This study found that fetal calf serum can protect Merkel cells from cell death and alter their morphology in culture from newborn rat whisker pads.

This case study reports that medical imaging of the ovaries may not always conclusively identify the cause of postmenopausal hyperandrogenism, as demonstrated by a patient with a rare condition.

In this scoping review and meta-analysis, researchers found that patients with alopecia areata show a complex serum chemokine profile, predominantly involving Th1- and Th2-associated chemokines, suggesting that broader immunomodulatory strategies might address the diverse immune dysregulation observed in the disease.

This study reports a case of an ovarian steroid cell tumor with malignant potential, presenting unusually with osteopenia and low weight instead of the expected virilizing symptoms.

This study found that storing hair micrografts in DMEM with apoptotic cell death inhibitors improved in vitro hair shaft elongation and reduced apoptosis, potentially enhancing micrograft transplantation outcomes.

This article is a letter to the editor discussing a rare case of Leydig cell tumor with type I diabetes mellitus causing female pattern hair loss, but it contains no abstract or new clinical findings.

This case report describes three instances where occult ovarian Leydig cell tumors were suspected based on severe hyperandrogenism symptoms, despite negative imaging findings, highlighting that elevated testosterone levels are a crucial diagnostic marker.

This study reviews the regulatory mechanisms and molecular processes governing stem cell activity in hair follicles, highlighting their roles in hair regeneration and potential implications for treating hair and skin disorders.

In this study, researchers found that serum granulysin levels might serve as a novel marker for disease activity in acute alopecia areata, being significantly associated with broader bald skin areas, poorer prognosis, and co-existing allergic disorders.

This review discusses the role of complement activation in SLE and suggests that while monitoring C3 and C4 remains important, increased levels of cell-bound complement activation products may better indicate disease activity.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

This study reveals that epidermal stem cell differentiation in mice involves dynamic transcriptional changes, with Keratin-10 transcription preceding gradual chromatin compaction shifts associated with differentiation.

Mutations in the Sgk3 gene cause fuzzy hair in mice.

This study found that a serum-free culture system supported hair growth from follicles responsive to calcium, glucose, and amino acids, with insulin enhancing the growth, while other factors had no effect.

This research presents a comprehensive workflow for producing EMA-compliant autologous keratinocyte-based therapies for wound healing and explores miRNA-mediated regulations in human keratinocytes and adipose-derived mesenchymal stem cells.

This case report describes a 69-year-old woman with hirsutism and elevated serum testosterone, where surgery resolved symptoms and serum testosterone, suggesting ovarian steroid cell tumor consideration in similar profiles.

This case report describes a postmenopausal woman with virilization and an ovarian steroid cell tumor, highlighting the rarity and diagnostic importance of such tumors in this demographic.

This study found a significant association between lower serum ferritin levels and chronic diffuse hair loss in women of reproductive age, particularly in cases of alopecia areata and androgenetic alopecia.
