This study demonstrates that hair follicle bulge stem cells can transition into other stem cell compartments, indicating their role in maintaining both hair follicles and sebaceous glands.

This article describes protocols for isolating and expanding human epidermal neural crest stem cells and discusses their potential for cell-based therapies in regenerative medicine, but reports no new clinical results.

This study found that low oxygen conditions and ECM degradation products increased the proliferation and migration of perivascular stem cells without altering their phenotype, suggesting potential roles in tissue repair.

This study found that adipose-derived stem cell extracellular vesicles reduced wrinkles and promoted cell proliferation in UVB-induced photoaging in mice by decreasing oxidative stress and inflammation.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.

This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.

This study found that steroid hormone levels in human hair correlate significantly with those in serum, suggesting hair may be a viable medium for assessing hormonal status.

This study found that shaving was the most helpful and commonly used temporary hair removal method among women with facial hirsutism.

This review discusses the role of stress mediators in skin diseases and reports no new clinical results; the authors suggest further research in skin psychoneuroimmunology.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This study found that activating autophagy with specific small molecules and drugs can stimulate hair growth by initiating the anagen phase in dormant hair follicles, suggesting a potential treatment for hair loss.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

In this study, researchers achieved complete reepithelialization and hair growth on a burn-injured scalp using a tissue-engineered dermal template with early micrograft hair follicle implantation.

Stem cells in developing hair follicles move to specific areas as they mature.

This review discusses the plasticity of stem cell populations and their ability to switch between functions for tissue homeostasis and regeneration, emphasizing environmental and hormonal influences, and reports no new results.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This study demonstrated that epidermal neural crest stem cells and bone marrow-derived stem cells migrated toward inflammatory brain lesions in rats and were successfully tracked using noninvasive MRI.

In this study, targeted deletion of the stearoyl-CoA desaturase 1 gene in mice disrupted the epidermal lipid barrier, leading to increased water loss, impaired thermoregulation, and metabolic issues.

This study reported that using human follicle stem cells isolated from hair bulge areas increased hair density by about 29% over baseline in patients with androgenetic alopecia, with significant improvements observed 23 weeks after the last treatment.

This study observed that melanogenesis in human hair follicles is linked to anagen phases, with melanocyte activity and enzyme expression being region-specific to the nascent bulb.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This study supports the idea that steatocystoma multiplex is a hamartomatous condition and suggests it may be a variant of eruptive vellus hair cyst, both originating in the pilosebaceous duct.

This retrospective study found that adipose-derived stem cell-conditioned media increased hair density and thickness in women with female pattern hair loss over 12 weeks, with no severe adverse effects reported.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.

This review discusses the role of corneodesmosin in skin and hair follicle integrity, with mentions of its link to hypotrichosis simplex and peeling skin disease, and reports no new results.

This study found that LGR5 may play a significant role in maintaining brain cancer stem-like cells and is associated with glioma progression and poor outcomes.

Vertebrate skin evolved to be more specialized and complex, especially in land animals.
