This study found that solid basal cell epitheliomas and the outer root sheath of human hair follicles display nearly identical cytokeratin profiles, suggesting a potential origin connection.

This study found that the in vitro growth of hair follicle cells, particularly papilla cells and outer root sheath keratinocytes, is influenced by different concentrations of androgens and antiandrogens.

This study found that in human hair bulbs, telomerase is present mainly in the nuclei of cells undergoing proliferation, particularly in the matrix epithelium during the anagen phase, and sparsely in the outer root sheath during late catagen and telogen phases.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This study found that cultured outer root sheath cells from human hair follicles expressed a keratin profile similar to their in vivo environment, indicating environmental influence on keratin expression.

In this study, the immunohistochemical and lectin binding profiles of basal cell carcinoma closely resembled those of the outer root sheath of vellus hair follicles, suggesting a potential histochemical relationship.

This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

LED light helps human hair root cells grow and move by activating certain cell pathways.

This study reports that EGF at specific concentrations promotes the proliferation and migration of hair follicle ORS cells by activating the Wnt/β-catenin signaling pathway in vitro.

This study found that human hematopoietic mesenchymal stem cells increased the viability and migration of human outer root sheath cells in an in vitro alopecia areata model, involving Wnt/β-catenin and JAK/STAT pathways.

This study suggests that particulate matter can induce inflammation in human outer root sheath cells, potentially affecting hair growth, through oxidative stress-dependent MAPK and JAK-STAT signaling pathways.

This study suggests that nerve growth factor may support hair follicle growth in Liaoning cashmere goats through pathways involving its receptor, TrkA, particularly during the anagen phase.

This study found that extracellular vesicles from mesenchymal and outer root sheath stem cells may inhibit hair follicle stem cell apoptosis, suggesting potential therapeutic benefits for hair loss treatments.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This study found that mesenchymal stem cells sourced from hair follicle outer root sheath showed higher differentiation efficiency and angiogenic potential for vascular graft applications compared to adipose-derived stem cells.

This study demonstrated that autologous mesenchymal stem cells from hair follicles, when combined with a novel gelatin-based hydrogel, showed promising osteogenic potential and could offer a non-invasive alternative for bone regeneration.

This research found that reduced expression of SIRT1 in human scalp tissue may contribute to alopecia areata development by inducing immune-inflammatory responses in hair follicle cells, suggesting that SIRT1 plays a regulatory role in hair follicle immunity.

This study found that inhibiting the TRPV3 channel may significantly promote hair growth and suggests a potential therapeutic approach for hair loss and related skin diseases.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

In this study, treatment with human follicular keratinocyte-conditioned media improved the trichogenicity of cultured dermal cells by activating key signalling pathways, suggesting its potential use in cell therapy for hair loss.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.
