research Human keratinocytes derived from the bulge region of hair follicles are refractory to differentiation
Hair follicle cells resist turning into skin cells.
research Immune response involving the bulge region in addition to telogen conversion contributes to hair loss in a case of atypical drug-induced hypersensitivity syndrome
Hair loss in a drug reaction case involved both a common shedding phase and an immune attack on hair follicle stem cells.
research Penetration Profile of Microspheres in Follicular Targeting of Terminal Hair Follicles
Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.
research In That Issue: Proceedings From the Third Intercontinental Meeting of Hair Research Societies
The meeting covered advances in understanding hair growth, causes of hair loss, and potential treatments.
research Expression and localization of Sox10 during hair follicle morphogenesis and induced hair cycle
Sox10 is important for hair follicle development and hair growth cycles.
research Evaluation of Two Medium-Depth Peels: Glycolic Acid 70% Versus Trichloroacetic Acid 35%: A Histological and Immunohistochemichal Study on Rat Skin
Both TCA and GA peels effectively improved skin thickness and collagen without significant differences.
research The effects of gamma rays on the regeneration of hair follicles are carried over to later hair cycles
Gamma-ray exposure can cause long-lasting damage to hair follicles, affecting hair structure and color.
research Predominant expression of interleukin (IL)‐17 in chronic alopecia areata compared to IFN‐γ in pathogenic Th17 cells, tissue‐resident memory T cells and natural killer cells
IL-17 is more important than IFN-γ in causing severe hair loss in chronic alopecia areata.
research The G-Protein Couple Receptor Kinase 2 (GRK2) Orchestrates Hair Follicle Homeostasis
GRK2 is essential for healthy hair follicle function, and its absence can lead to hair loss and cysts.
research Primary Cicatricial Alopecias
Early diagnosis and aggressive treatment are key for managing rare scalp disorders that cause permanent hair loss.
research Telocytes in human skin – are they involved in skin regeneration?
Telocytes might help with skin repair and regeneration.
research Impact of the Different Preparation Methods to Obtain Autologous Non-Activated Platelet-Rich Plasma (A-PRP) and Activated Platelet-Rich Plasma (AA-PRP) in Plastic Surgery: Wound Healing and Hair Regrowth Evaluation
Different methods of preparing Platelet-Rich Plasma (PRP) can affect wound healing and hair regrowth in plastic surgery. Using a kit with specific standards helps isolate PRP that meets quality criteria. Non-Activated PRP and Activated PRP have varying effects depending on the tissue and condition treated. For hair regrowth, Non-Activated PRP increased hair density more than Activated PRP. Both treatments improved various aspects of scalp health.
research Brg1 Governs a Positive Feedback Circuit in the Hair Follicle for Tissue Regeneration and Repair
Brg1 is crucial for hair growth and skin repair by maintaining stem cells and promoting regeneration.
research Primary cicatricial alopecia: Recent advances in understanding and management
New understanding of the causes of primary cicatricial alopecia has led to better diagnosis and potential new treatments.
research Alteration of Skin Wound Healing in Keratinocyte-Specific Mediator Complex Subunit 1 Null Mice
MED1 affects skin wound healing differently in young and old mice.
research Identification of Functional Patterns of Androgenetic Alopecia Using Transcriptome Profiling in Distinct Locations of Hair Follicles
AGA linked to inflammation, stress, fibrosis, and disturbed hair follicle stem cells.
research Controversial Concepts
The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.
research Effects of gamma rays on the regeneration of murine hair follicles in the natural hair cycle
Gamma rays did not change hair follicle density but increased white and hypopigmented hairs in mice.
research Age-induced hair greying - the multiple effects of oxidative stress
Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.
research Identification of hair shaft progenitors that create a niche for hair pigmentation
Scientists found cells in hair that are key for growth and color.
research Epimorphin expression during human foetal hair follicle development
Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.
research Manifest hair repigmentation associated with etretinate therapy
An 82-year-old man's white hair regained color after taking etretinate for psoriasis.
research 865 Conditional ablation of JAK-STAT5 signaling induces anagen hair growth
Blocking JAK-STAT5 signaling in mice leads to hair growth.
research Réparer ou régénérer,il faut choisir…
Mammals can regenerate new hair follicles from skin stem cells.
research Changes in the sebaceous gland in patients with male pattern hair loss (androgenic alopecia)
Sebaceous glands in male pattern hair loss patients have more lobules and might cause early hair growth phase shifts.
research Integral Roles of Specific Proteoglycans in Hair Growth and Hair Loss: Mechanisms behind the Bioactivity of Proteoglycan Replacement Therapy with Nourkrin® with Marilex® in Pattern Hair Loss and Telogen Effluvium
Proteoglycans are important for hair growth, and a specific treatment can help reduce hair loss.
research The human hair: from anatomy to physiology
The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
research Inducible deletion of epidermal Dicer and Drosha reveals multiple functions for miRNAs in postnatal skin
Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.
research Morphometric Analysis of the Human Scalp Hair Follicle: Practical Implications for the Hair Transplant Surgeon and Hair Regeneration Studies
