research Dermal Papilla Cells: From Basic Research to Translational Applications
Dermal papilla cells can help regrow hair and are promising for hair loss treatments.
research The feasibility of quantitative analysis of androgen metabolism by use of single dermal papillae from human hair follicles
Using single dermal papillae is unreliable for analyzing androgen metabolism in hair follicles.
research Functional hair follicle regeneration: an updated review
Hair follicle regeneration possible, more research needed.
research Expression of SPARC (secreted protein acidic rich in cysteine) throughout the hair cycle in rats
SPARC likely aids in tissue remodeling during the hair cycle, not in starting new hair growth phases.
research The Dynamic Duo: Niche/Stem Cell Interdependency
Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.
research Hair Cycle-Dependent Expression of Hepatocyte Growth Factor (HGF) Activator, Other Proteinases, and Proteinase Inhibitors Correlates with the Expression of HGF in Rat Hair Follicles
research α3β1-integrin regulates hair follicle but not interfollicular morphogenesis in adult epidermis
α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.
research Cutaneous Epithelial Stem Cells
Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.
research Dynamics of Hair Follicle Morphogenesis and Skin Homeostasis
Hair follicle development involves specific cells and genes, crucial for understanding severe skin diseases like harlequin ichthyosis.
research Aesthetic Importance of the Parietal Eminence Area (Posterior Parietal Triangle), an Essential Island of Scalp Requiring Hair Restoration
Hair restoration should include the parietal eminence area for better balance in frontal and lateral profiles and to improve the head's contours.
research An Integrated Transcriptome Atlas of Embryonic Hair Follicle Progenitors, Their Niche, and the Developing Skin
The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.
research Activation of β-Catenin Signaling in CD133-Positive Dermal Papilla Cells Drives Postnatal Hair Growth
Activating β-catenin in certain skin cells speeds up hair growth in mice.
research Dermal papilla cells from human hair follicles secrete factors (e.g. VEGF) mitogenic for endothelial cells.
Dermal papilla cells help hair growth by releasing growth-promoting factors.
research Contrast enhanced phototrichogram (CE-PTG): an improved non-invasive technique for measurement of scalp hair dynamics in androgenetic alopecia–validation study with histology after transverse sectioning of scalp biopsies.
CE-PTG is a better method for analyzing hair growth in androgenetic alopecia.
research Pili Annulati
The patient's hair has unique structural differences with alternating bright and dark bands.
research Human hair keratins
research Human hair follicle cells of outer root sheath maintain their genuine keratin expression in vitro
research The incidental pore: CaV1.2 and stem cell activation in quiescent hair follicles
CaV1.2 helps activate hair follicle stem cells without calcium flux.
research Cultivation of Human Hair Follicle Cells
research Synergy of understanding dermatologic disease and epidermal biology
Advancements in skin and hair biology improve dermatology care and cosmetic treatments.
research Pseudopili Annulati in a Dark‐Haired Individual: A Light and Electron Microscopic Study
A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research CD49fhigh Defines a Distinct Skin Mesenchymal Stem Cell Population Capable of Hair Follicle Epithelial Cell Maintenance
A specific group of skin stem cells was found to help maintain hair follicle cells.
research Raising hairs
Stem cell treatments can potentially treat baldness, with one trial showing hair growth after injecting a hair-stimulating complex, and no safety issues were reported.
research Neuroendocrinology of the hair follicle: principles and clinical perspectives
Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.
research A Contemporary View on Felix Pinkus’ Concept of the Vitreous Membrane
The vitreous membrane in hair follicles changes shape during the hair cycle and may affect hair growth and nutrient exchange.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research Hair Follicle Culture
Hair follicle culture helps study hair growth but has limitations in modeling the full hair cycle.
research The roles of hepatocyte growth factor family members in androgen-regulation of human hair growth. A comparison of the expression of hepatocyte growth factor family members, HGF and MSP, and their receptors, c-Met and RON, in isolated hair follicles from normal and androgenetic alopecia (balding) scalp.
Balding hair follicles have reduced growth factors and increased inhibitory factors, suggesting new treatment paths for hair loss.
