This review discusses the association between scarring alopecia and inflammatory processes in common acquired bullous disorders of the scalp, and reports no new clinical findings.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

The technique effectively repairs skin after tumor removal, maintaining appearance and function without complications.

This review discusses the regenerative potential of hair follicle stem cell populations and current approaches to reconstructing folliculogenesis for alopecia therapy, but reports no new clinical results.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

The document concludes that understanding hair biology is key to treating hair disorders, with gene therapy showing potential as a future treatment.

This article reviews the progress in hair biology research, including advancements in understanding androgen action, hair follicle stem cells, and autoimmune mechanisms in alopecia, and reports no new clinical results.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

Certain proteins involved in DNA modification may affect the genetic changes in systemic lupus erythematosus and could indicate the disease's activity.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This study found that in vivo confocal scanning laser microscopy accurately quantifies neogenic hair follicles in mice, producing results similar to histology while avoiding fixation artifacts.

This study found that β-catenin is essential for hair follicle stem cell proliferation and may regulate this process through the PI3K/Akt pathway, suggesting its potential as a therapeutic target.

This study found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

This study found that co-culturing dermal papilla cells in a 3D structure with adipose-derived stem cells may enhance the expression of hair inductivity markers compared to 2D cultures.

This study introduced a reproducible human model using 3D-SeboSkin technology to study hidradenitis suppurativa, allowing better maintenance of skin integrity and replication of biomarker expression patterns compared to traditional skin cultures, suggesting its value for further research.

Japanese researchers created new hair follicles from human cells that grew hair when put into mice, and other findings showed a link between eye disease severity and corneal thickness, gene mutations affecting hearing and touch, and the safety of the shingles vaccine for adults over 50.

This research suggests that plucked hair follicles may serve as a reliable surrogate tissue for tumor biopsies in drug development, based on a mouse model linking hair and tumor pharmacodynamic responses.

This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This article reviews the role of stromal stem cells in mammalian wound repair, suggesting they may perform functions similar to blastemal cells in simpler organisms, but reports no new experimental results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study found that Smad7 perturbs hair follicle development while promoting sebaceous gland formation by antagonizing Wnt/β-catenin signaling in transgenic mice.

This review discusses current and emerging treatments for benign prostatic hyperplasia and emphasizes the need for further research to optimize treatment selection, but reports no new clinical results.

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.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This study reported that using human follicle stem cells isolated from hair bulge areas increased hair density by about 29% over baseline in patients with androgenetic alopecia, with significant improvements observed 23 weeks after the last treatment.
