This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

In this study, 25% of CCHCR1-deficient mice exposed to stress developed hair loss similar to human alopecia areata, suggesting CCHCR1 is a susceptibility gene for the disease.

This study found that genetic ablation of Tet genes in mice led to changes in hair structure and keratin gene expression, indicating a role for Tet-mediated 5hmC DNA oxidation in hair follicle development and cycling.

This Ph.D. project aims to evaluate the self-assembling potential of hair keratin extracts and study the cellular response to both crude and purified keratins, highlighting their potential applications from biomedical to water remediation.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found multipotent progenitors in sweat ducts that become unipotent after sweat gland development, highlighting distinct regenerative capabilities in adult glandular skin stem cell populations.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This research overview highlights that although JAK inhibitors show promise as potential treatments for alopecia areata based on recent insights into the disease mechanism, their efficacy has not yet been thoroughly evaluated in a systematic manner.

This study explored the effectiveness of the oral JAK1/2 inhibitor ruxolitinib in treating patients with moderate-to-severe alopecia areata, building on prior success with JAK inhibitors in mice, but results are not reported in this abstract.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

This review discusses keratin disorders and potential RNA interference therapeutics, reporting no new clinical findings but highlighting the promise of siRNA for future treatments.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study identified a cluster of genes on chromosome 17 related to hair keratin-associated proteins, including 37 genes forming seven multigene families, localized in the hair shaft's upper cortex.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review outlines a diagnostic framework for clinicians to distinguish different types of inherited ichthyoses and suggests further testing and treatment strategies, but reports no new clinical results.

This review discusses recent advances and ongoing clinical trials in novel therapeutics for alopecia areata, despite the lack of current FDA-approved treatments for severe cases, and reports no new results.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This study demonstrates that YAP and TAZ are essential for initiating basal and squamous cell carcinomas in mice, and suggests targeting these pathways could be beneficial for treating skin cancers.

In this study, specific genetic polymorphisms in the KRT71 gene were associated with hairless and curly phenotypes in Sphynx and Devon Rex cats.

In this study, oral tofacitinib treatment led to significant hair regrowth and changes in skin and blood biomarkers in a patient with alopecia areata.
