This review highlights that collagen XVIIα1's role in maintaining dermal-epidermal junction integrity and hair follicle stem cell maintenance is compromised with age due to reduced levels and increased processing, potentially affecting skin and hair aging.

In this study, researchers developed a new method called Enriched-GF, which enhances growth factor recovery from platelet concentrates through a combination of glass bead activation, freeze-thaw cycling, and calcium stimulation, outperforming conventional methods by providing higher and more consistent yields for regenerative medicine applications.

This review highlights the multifaceted roles of hair follicles in skin health, emphasizing their contribution to skin tumorigenesis, homeostasis, and wound healing, and how dysregulation in associated pathways like Wnt, Hedgehog, and Notch may contribute to skin cancer development.

In a mouse model of androgenetic alopecia, this study found that a novel hydrogel containing minoxidil-incorporated engineered exosomes (Gel@MNs) enhanced hair regeneration more effectively than conventional minoxidil, increasing hair follicle number and size while reducing skin irritation.

In this study, it was observed that topical application of N,N-Dimethylglycine Sodium Salt significantly increased skin microcirculation and blood flow in human subjects, suggesting potential benefits for skin health and conditions like dermatitis.

In a mouse model of androgenetic alopecia, this study developed a treatment combining a copper-curcumin nanoparticle oleogel with traditional Gua Sha therapy, which augmented hair regeneration more effectively than minoxidil by improving the follicular microenvironment and regulation of inflammatory responses.

This study found that mitochondrial dysfunction in the epidermis contributes to aging-related changes in hair follicles among mice, with aged mice showing reduced hair density and delayed regrowth, suggesting that maintaining mitochondrial function may help prevent age-related organ decline.

This review examines how growth factors and cytokines influence mammalian hair growth and highlights the impact of their dysregulation, but it presents no new experimental findings.

This study suggests that human skin contains distinct fibroblast subsets with unique expression profiles and functions, which can be isolated to investigate their role in skin pathogenesis.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

This study found that low-level laser therapy may enhance wound healing and reduce pain, swelling, and inflammation by increasing mitochondrial activity and oxidative stress, leading to greater protein synthesis and cell proliferation.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This study found that dermal papilla cell-derived exosomes may enhance hair follicle regeneration during wound healing by boosting fibroblast hair-inducing capacity and activating the Wnt/β-catenin signaling pathway.

This review discusses recent advances in using stem cells for skin repair and regeneration after severe burn injuries, but it reports no new clinical results.

This study reports that incorporating Lef-1 transfected dermal papilla cells into human skin equivalents significantly promoted hair follicle differentiation and hair fiber growth, offering a potential advancement for managing skin loss.

This study found that EGCG improved the integrity of skin grafts during cryopreservation, suggesting its potential usefulness for skin preservation, though the exact mechanism remains unclear.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

This study found that topical olive oil may protect mice skin from damage caused by electromagnetic radiation, particularly when applied before exposure, by mitigating oxidative, inflammatory, and heat shock stress factors.

This article reviews the role of keratins in epithelial tissues, emphasizing their importance for regular function, and reports no new experimental results.

In this study, researchers identified slow cycling label retaining cells in nail and sweat gland appendages, showing stem cell characteristics similar to hair follicles but with distinct features.

This study found that Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

In this study, researchers found that using bioinspired nanovesicles derived from inflammation memory-activated epidermal stem cells effectively promoted healing in diabetic wounds by reprogramming neutrophils to an anti-inflammatory phenotype in both laboratory and animal models.

Small molecule DMF improves psoriasis and multiple sclerosis, adult skin cells can be made to grow new hair, certain skin cells initiate hair growth, IL-17C controls gut health and can cause skin inflammation, and skin cells produce IL-17 that can lead to psoriasis.

This case study in an 8-month-old mixed-breed dog with symptoms and histopathological findings supports a diagnosis of hereditary junctional epidermolysis bullosa, although specific genetic mutations weren't identified.

This study developed a novel hydrogel dressing, QL@MAB, which facilitates accelerated healing of infected diabetic wounds in rats by offering prolonged drug release, water retention, and adaptive drug delivery in response to high glucose levels in the wound environment.

This study tested a natural hair dye made from papaya seed extract, celery leaf, and avocado, finding color change in animal hair but also noting tissue changes like hyperkeratosis.

This study developed in vitro methods to regenerate hair follicles and erector muscles by mimicking their native structures and mechanical conditions, reconstructing hair follicle-like structures and forming muscle-like tissues.

This paper provides evidence supporting the formation of new hair follicles in adult humans, building on findings previously demonstrated in rabbits.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that vitamin D receptor mutations lead to hair follicle alopecia due to impaired cyclic regeneration, which is distinct from vitamin D receptor effects on epidermal keratinocytes that largely depend on 1,25-dihydroxyvitamin D.
