TCDD speeds up skin barrier formation by increasing certain gene expressions.
research Pulling force deforms hair follicle root sheath nuclei and surrounding dermal collagen matrix differently at infundibulum, isthmus and suprabulbar regions
Hair follicles respond differently to pulling forces in various regions.
research A function for Rac1 in the terminal differentiation and pigmentation of hair
Rac1 is essential for proper hair structure and color.
research Force-triggered density gradient sedimentation and cocktail enzyme digestion treatment for isolation of single dermal papilla cells from follicular unit extraction harvesting human hair follicles
New methods efficiently isolate dermal papilla cells from hair follicles, preserving their characteristics better than traditional methods.
research Hair color digitization through imaging and deep inverse graphics

research 2008 Best of the Rest in Urological Survey
research Pemphigus vulgaris in only one of two monozygotic twins
Genetic factors alone might not cause pemphigus vulgaris; other factors like birth complications and puberty may trigger it.
research Is Dihydrotestosterone a Classic Hormone?
Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.
research Shh maintains dermal papilla identity and hair morphogenesis via a Noggin–Shh regulatory loop
Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.
research Comparative analysis of stemness between dermal papilla cells and human dermalstem/progenitor cells
Human dermal stem/progenitor cells can divide and differentiate more than hair follicle dermal papilla cells.
research Faculty Opinions recommendation of Does D matter? The role of vitamin D in hair disorders and hair follicle cycling.
Vitamin D receptor is key to hair growth, not vitamin D itself.
research The skin and vitamin D
The skin produces and uses vitamin D for bone health, cell growth, and immune function.
