research 250 Sweat glands shrink upward with aging, causing dermal layer defects that lead to loss of skin elasticity and wrinkling-establishment of 3D imaging method for skin appendages
Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.
research Histochemistry of the human hair follicle with consideration of anagen phases I to VI
Human hair follicles have a unique cell distribution and differentiation pattern during growth.
research Module-based complexity formation: periodic patterning in feathers and hairs
The conclusion is that understanding how feathers and hairs pattern can help in developing hair regeneration treatments.
research In brief
Pilomatricomas don't follow the usual hair follicle cell differentiation process.

Increasing type 17 collagen reduces aging signs in skin cells caused by UV light.
research Newborn infant skin gene expression: Remarkable differences versus adults
Newborn skin is uniquely prepared to adapt to new environments compared to adult skin.
research Pelage cycle in blue fox(Alopex lagopus):A comparison between animals born early and late in the season
Blue foxes born later in the season have a slightly delayed fur growth cycle, but it catches up by mid-November.
research Reprogramming of Aged Dermal Papilla Cells in Vitro: In Silico Insight into the Biomarkers of Hair Growth and Tissue Repair
Aging dermal papilla cells can be reprogrammed for potential hair growth and skin repair.
research Generating iPSCs with a High-Efficient, Non-Invasive Method—An Improved Way to Cultivate Keratinocytes from Plucked Hair for Reprogramming
The conclusion is that the new method makes collecting cells from plucked hair to create stem cells more efficient and less invasive.
research Exploring the Chorioallantoic Membrane (CAM) as a Platform for Burn Wound Modelling and Analysis
The CAM is a useful model for studying burn wounds and testing treatments.
research Basement membrane components define the microenvironment of aggregated fibroblasts in the skin and support their aggregation in vitro
Basement membrane-like ECM supports fibroblast aggregation and cohesion.
research Analysis of clinical and histologic correlations in alopecia areata and telogen effluvium: adversities in alopecia pattern mimicry.
The study found that it's hard to tell the difference between two types of hair loss, alopecia areata and telogen effluvium, by looking at symptoms and tissue samples.
research Keratin 15 promotes a progenitor cell state in basal keratinocytes of skin epidermis
Keratin 15 helps keep skin cells in a young, undifferentiated state.
research Original Article : Fabrication and Characterization of Epithelial Scaffolds for Hair Follicle Regeneration
The study found that certain three-dimensional scaffolds can help regenerate hair effectively.
research Clinical Snippets
Skin has a larger surface area than thought, certain skin cells improve skin flap survival, better trials for skin conditions in children are needed, Stevens-Johnson syndrome rates vary by age and race, and better skin barrier function may reduce inflammation in the elderly.
research Dermal fibroblasts in the focus of modern cosmetology: aging and response to cosmetic procedures: A review
Understanding fibroblasts helps improve cosmetic treatments for aging skin.
research 591 A New 3D Skin Model Containing Autologous Immune Cells Reconstructed by Tissue Engineering
Researchers developed a 3D skin model with its own immune and blood vessel cells to better understand skin health and disease.
research Laminin 332 Is Indispensable for Homeostatic Epidermal Differentiation Programs
Laminin 332 is essential for normal skin cell behavior and structure.
research Trajectory of hiPSCs derived neural progenitor cells differentiation into dermal papilla-like cells and their characteristics
Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.
research 918 Skin morphogenesis by coupling biochemical-bioelectric signals: Calcium oscillations coordinate dermal cell movement by epidermis-derived SHH signaling during feather bud orientation
Calcium signals and SHH guide the direction of feather growth in chicken skin.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Intercellular junctions in normal epidermis
Desmosomal adhesion is essential for healthy skin structure and function.
research Linear trichoepithelioma on the neck of a 15-year-old girl
A 15-year-old girl has a benign skin tumor on her neck.
research Optical coherence tomography-assisted diagnosis of follicular keratosis of the chin
OCT can non-invasively diagnose follicular keratosis and other hair follicle disorders.
research Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Lichen planopilaris
A 20-year-old had hair loss and skin issues from lichen planopilaris starting at age 10.
research Rescuing key native traits in cultured dermal papilla cells for human hair regeneration
Conditioned medium from keratinocytes can improve hair growth potential in cultured dermal papilla cells.
research Ability of Transplanted Cultured Epithelium to Respond to Dermal Papillae
Cultured epithelium can form hair follicles when combined with dermal papillae.
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.
