This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

In this study, the bending stiffness of human hair was linked to the varying proportions of para-like versus ortho-like cortical cells within the hair fiber.

This study found that tdDPC-EVs significantly improved wound healing by enhancing angiogenesis through the KLF4/VEGFA axis, offering advantages over traditional DPC-EVs.

This study found that HAMA hydrogels promote faster healing of skin wounds in mice by enhancing the accumulation of anti-inflammatory macrophages and increasing type III collagen in the local wound environment.

This study found that hypoxia-preconditioned HF-MSC-derived exosomes improved therapeutic outcomes in models of ulcerative colitis, potentially through miR-214-3p-mediated pathways affecting mitochondrial function and inflammatory responses.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

This study found that using an electrical microneedling device enhanced the penetration of liposomal melanin-fluorescein into hair structures and widened the follicular infundibulum in ex vivo human skin models.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

This study found that the circadian clock regulates the activation state of murine epidermal stem cells, affecting tissue homeostasis and susceptibility to tumorigenesis when disrupted.

This study found that ZnO nanoparticles in topical skin products do not penetrate beyond the outer skin layers in humans, suggesting minimal safety concerns for subdermal absorption.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This study found that CRISPR/Cas9-mediated disruption of the FGF5 gene in goats increased hair follicle numbers and fiber length, suggesting more cashmere production could be achieved.

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, a novel mutation in the glucocorticoid receptor gene was identified in a young woman, impairing glucocorticoid signaling and leading to generalized glucocorticoid resistance.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This review discusses the biology of hair follicle stem cells and highlights their potential for applications in regenerative medicine, drug, and gene delivery, but reports no new clinical results.

This review discusses the role of lamins in development, tissue maintenance, and stress response, and does not report new experimental findings.

Minoxidil promotes hair growth by increasing cell division and DNA synthesis.

This study observed that skin pigmentation significantly attenuates bioluminescent signals in C57Bl/6 mice, complicating quantitative optical imaging and requiring consideration in experimental design.

This study demonstrated that hair follicle-derived cells can induce hair follicle formation in an in vitro skin organ culture system using human retroauricular skin specimens.

The study found that severe insulin resistance and premature diabetes are common in patients with PCNT genetic defects, primarily affecting those over four years old, while not impacting early insulin signaling in adipocytes.
