Glossary Follicular Keratinocytes

specialized cells in hair follicles producing keratin for hair

Follicular keratinocytes are specialized cells found in hair follicles, the structures in the skin that produce hair. These cells are responsible for producing keratin, a protein that forms the structural foundation of hair. They play a crucial role in the growth and health of hair by continuously dividing and differentiating to form the hair shaft.

research The cell-surface marker MTS24 identifies a novel population of follicular keratinocytes with characteristics of progenitor cells

207 citations , July 2006 in “Development”

This study identified a novel MTS24-positive murine keratinocyte population with increased colony-forming ability, suggesting these cells may serve as a new reservoir of proliferative progenitor or stem cells in hair follicles.

research Dihydrotestosterone-Inducible Dickkopf 1 from Balding Dermal Papilla Cells Causes Apoptosis in Follicular Keratinocytes

171 citations , July 2007 in “Journal of Investigative Dermatology”

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

research Cyclosporin A-induced hair growth in mice is associated with inhibition of calcineurin-dependent activation of NFAT in follicular keratinocytes

57 citations , June 2003 in “American Journal of Physiology-cell Physiology”

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

research Regulation of PDGF and PDGF receptor in cultured dermal papilla cells and follicular keratinocytes of the human hair follicle

55 citations , September 2003 in “Experimental Dermatology”

In this study, researchers found that certain cytokines can significantly down-regulate PDGF expression in dermal papilla cells and follicular keratinocytes, indicating a potential link between PDGF signaling and catagen induction.

research Hair growth induction by the tellurium immunomodulator AS101: association with delayed terminal differentiation of follicular keratinocytes and ras‐dependent up‐regulation of KGF expression

51 citations , December 2003 in “The FASEB Journal”

community Minoxidil Response Bottlenecks: Why Sulfation and Transport Matter (And Where Tretinoin Fits In)

in Research 461 upvotes 1 year ago

Minoxidil's effectiveness is limited by the need for sulfation and proper transport to hair follicles, with tretinoin potentially enhancing its effects by promoting enzyme activity and keratinocyte differentiation. Tretinoin may improve minoxidil's response by boosting the expression of necessary enzymes and transporters.
