The document concludes that proper diagnosis and treatment of nonscarring alopecias can improve quality of life and hair regrowth is possible as the hair follicle remains intact.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This review highlights that nanocarrier-based formulations, using both synthetic drugs and natural components, show promise in overcoming the limitations of current androgenetic alopecia treatments with modified release profiles and enhanced drug delivery, though clinical trials remain limited.

In this study, Maas-Szabowski and Szabowski revealed that c-Jun and JunB transcription factors, as well as granulocyte macrophage-colony stimulating factor, regulate human keratinocyte growth and differentiation in fibroblast–keratinocyte interactions.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

In this study, penetration of FA-PLGA nanoparticles into hair follicles was observed in excised dog, rat, and porcine skin, with the deepest penetration in porcine skin, suggesting its similarity to human skin for drug delivery studies.

In this review, the authors explored the diverse roles of fibroblasts in wound healing, suggesting that understanding their complexity could lead to better insights into wound pathologies and the development of new treatments.

This study reviews the complex keratinization process in the epidermis, detailing how various factors regulate keratinocyte differentiation and emphasizing the importance of understanding this process for the pathogenesis of skin disorders like ichthyoses and psoriasis.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

This review discusses how the nuclear lamina integrates biochemical and mechanical signals to influence gene expression and skin homeostasis, but reports no new clinical results.

In this study, Far2-/- mice were observed to develop focal alopecia with altered sebaceous gland morphology and lower skin lipid levels compared to wildtype mice.

This study provides new insights into the identification and expression patterns of miRNAs in wool follicles, which could improve understanding of wool follicle development in sheep.

This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study developed a culture method to expand and differentiate primary mammary basal cells, identifying key transcription factors like EGR1 and ELF3 that influence Claudin expression and actin organization, offering insights into epithelial cell biology and potential applications in related research fields.

This symposium review highlights past, present, and future developments in skin research, celebrating the work of Prof. Johanna Brandner and Dr. Peter Arne Gerber, without reporting new clinical results.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

This study found that plasma Claudin 3 levels were linked to alopecia areata severity among patients compared to healthy controls.
