This study found that SIRT1 negatively regulates fibroblast activation and excessive scar formation, suggesting it may be a promising drug target for treating hypertrophic scars.

This study found that ECMs from papillary and dermal papilla fibroblasts support normal basement membrane formation, suggesting potential improvements for therapeutic biomaterials in skin engineering.

This study found that the peptide TSN6 increased epidermal thickness and promoted hair follicle formation in dermal–epidermal composites grafted onto nude mice, with TSN6-treated composites showing more hair follicles and retained grafts compared to control groups.

This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

In this study, fetal rat wounds at gestational age 16 days healed without scar formation and resembled normal skin architecture, unlike those at 18 days which resulted in scarring and lack of hair follicles.

This review highlights that microRNAs (miRNAs) play crucial roles in hair follicle development and cycling in cashmere goats, detailing recent advances in understanding their regulatory functions and potential applications in improving cashmere fiber quality and diagnosing hair disorders.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

This paper reviews the complex anatomy and development of human hair and emphasizes the need to understand these processes for interpreting drug incorporation into hair, with no new clinical results reported.

This study found that twice-daily intradermal injections of mouse epidermal growth factor in Merino sheep resulted in dose-dependent changes in wool follicles and fibres, including induction of catagen and subsequent regeneration.

This review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

This review discusses fetal hair follicle development and its importance for determining in utero drug exposure through neonatal hair, but it reports no new clinical results.

In this study, researchers examined the skin of Baikal seals, identifying two main skin pathologies potentially linked to global warming and an unknown viral pathogen, suggesting immune inflammatory processes associated with environmental changes may be affecting these seals.

This study found that mutations in the Foxn1 gene in nude mice affect not only hair but also nail structure and differentiation, offering insights into nail hypergranulosis pathogenesis relevant to human nail diseases.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

This review summarizes recent advances in understanding intermediate filament structure and their implications for pathological mutations and human diseases, but it reports no new experimental results.

This review discusses recent advances in the development of electrospun pectin nanofibers for biomedical applications, highlighting strategies to improve their mechanical properties and biological functions and addressing challenges like material variability and regulatory issues.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

In this study, the researchers observed that ferulic acid and resveratrol effectively protected chemically treated hair from oxidative damage, particularly against protein loss and color degradation, but not cisteine oxydation prevention, and these antioxidants also offered protection against sun-induced damage when used in conditioners.

In this study, the researchers developed a novel wound dressing incorporating copper-doped calcium silicate and curcumin, which significantly promoted nerve and blood vessel regeneration in deep burn wounds, emphasizing the crucial role of bioactive chelation in neuralized skin repair.

This study found that infused mouse epidermal growth factor induced wool follicle involution through a quasi-physiological process similar to catagen and a separate pathological action, resulting in fleece 'break' or shedding.

This study explored the use of microneedling for dermatological disorders, highlighting its benefits like increased collagen and elastin production, dermal thickening, and skin rejuvenation, making it suitable for conditions such as scars, stretch marks, and photoaged skin.

This study found that transparent shampoo bars containing high concentrations of aloe vera gel, castor oil, and cinnamon oil exhibited antimicrobial activity, reduced hair loss, and caused no skin irritation.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

This study reported that keratin films lacking keratin-associated proteins showed different appearance, structure, and color deposit properties compared to conventional keratin films, suggesting potential for evaluating hair damage.
