This study found that plucked hair follicles can serve as a practical and scalable source for regenerative medicine, as researchers successfully isolated and expanded keratinocytes and mesenchymal stem cells for potential cell-based and cell-free therapies, demonstrating significant wound-healing bioactivity in vitro.

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

This abstract omits specific findings and does not provide new research results.

This study highlights the significance of the hf pathway for the skin permeation of ionized and hydrophilic high molecular compounds, and the usefulness of hf-plugging in evaluating their skin permeability.

In this study, researchers analyzed skin tissues from two types of Jinlan Cashmere Goats and identified crucial non-coding RNA mechanisms potentially impacting cashmere yield, revealing significant DE lncRNAs, mRNA expressions, and pathways relevant to cashmere quality improvement.

This study observed that a topical serum containing Silybum marianum extract, manganese PCA, and Lespedeza capitata extract enhanced hair follicle growth and hair shaft elongation, while prolonging the anagen phase in an ex vivo human scalp skin model, suggesting potential benefits for hair loss treatment.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

This study introduced a semi-automatic hair follicle implanter that can reduce surgery time and fatigue for both patients and surgeons, with effectiveness demonstrated in animal and clinical trials.

This study found that increasing methionine in the diet of pregnant rabbits may stimulate the development of hair follicles and improve hair fiber diameter in their offspring.

This mathematical model of alopecia areata illustrates how inflammatory autoimmune responses interrupt the anagen phase of hair growth, and may help evaluate treatments and identify new therapeutic targets.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

In this study, researchers found that while both hair follicles and skin dermis-derived neural crest stem cells are suitable for large-scale manufacturing, skin dermis cells grow faster and are easier to obtain.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This study found that irisin, a myokine, increases hair growth by activating the Wnt/β-catenin pathway, enhancing cell proliferation and hair shaft elongation in both human cell and mouse models.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that extracellular vesicles from stimulated human dermal fibroblasts enhanced hair follicle growth ex vivo by activating dermal papilla cells and involving the Norrin and β-catenin pathways.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

In this study, a nanoemulsion containing lavender, peppermint, and rosemary essential oils was developed and shown to promote hair growth in mice at a rate comparable to 2% topical minoxidil, suggesting a promising natural alternative due to its antioxidant and anti-inflammatory effects.

This study proposes that intranasal exposure to PTx and autoantigen in an animal model can trigger autoimmune disease, supporting the idea that subclinical nasal colonization by BP may cause alopecia areata.

This study found that incorporating human adipose subcutaneous tissue in 3D organotypic skin cultures mimicking hypertrophic scar conditions improved epidermal homeostasis, formed a basement membrane similar to native skin, and reduced myofibroblast presence, indicating an anti-fibrotic effect.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.
