This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This review discusses the role of hormonal dysregulation and metabolic syndrome in hidradenitis suppurativa and reports no new clinical results.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study found that the selective PPARγ modulator GMG-43AC may inhibit unwanted hair growth by inducing catagen phase while preserving hair follicle epithelial progenitor cells, suggesting potential in anti-hirsutism therapy.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

This review describes the dermatological uses of the contraceptive ethinylestradiol/chlormadinone acetate for conditions linked to high androgen levels and reports no new clinical results.

This study found that serum irisin levels were significantly lower in patients with acne vulgaris compared to healthy controls and were negatively correlated with insulin resistance and disease severity.

This review outlines the clinical and histopathological features that aid in classifying tumors arising from the folliculosebaceous apparatus and reports no new research results.

This study determined the broad class and molecular species of glycerophospholipids in Eastern red bat sebum, highlighting differences from previous bat lung surfactant studies.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study found that multiple treatments combining NIR laser phototherapy with ICG significantly reduced inflammation and improved skin condition in acne without side effects.

This article explains the significance of culturing the pilosebaceous unit for studying related diseases and skin epithelial stem cells, but it reports no new findings.

This study found that hirsutism in women is associated with elevated androgen hormone levels and increased serum TNFα, suggesting a link between androgen-driven inflammatory responses and excessive hair growth.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

This review discusses the evolving understanding of epithelial stem cells, noting how new models challenge old assumptions and suggesting multiple stem cell populations contribute differently to skin and hair follicle regeneration.

This article discusses the treatment considerations for a 17-year-old boy with a six-month history of acne but reports no new research findings.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This review discusses the advancements in understanding and treating androgenetic alopecia and alopecia areata but reports no clinical findings; the authors emphasize the need for further research on molecular control mechanisms.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This study found that testosterone therapy in trans men increased facial and body hair growth while the prevalence and severity of acne peaked at 6 months but were primarily mild after long-term treatment.

This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.

This review discusses acquired hypertrichosis lanuginosa, a rare disorder often linked to internal malignancy, and reports no new clinical findings; the authors highlight proposed pathogenic mechanisms for lanugo hair overgrowth.

This study found that in mouse skin, the activation of stem/progenitor cells is synchronized across different niches during growth, with the glutamate transporter SLC1A3 playing a crucial role in this process.

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

This review discusses various resveratrol derivative patents for therapeutic, nutraceutical, and cosmetic use, but reports no clinical results and notes that claims of improved efficacy lack trial evidence.

This article reviews the use of hormonal therapies in dermatology, specifically focusing on their pathophysiologic rationale, indications, commonly used drugs, and pretreatment evaluations, and it reports no new research findings.

This study found that follicular stem cells in hair follicles are more sensitive to the antiproliferative effects of glucocorticoids compared to basal keratinocytes due to incomplete desensitization.
