Glossary Outer Root Sheath Keratinocytes

specialized cells in the hair follicle's outer layer

Outer Root Sheath Keratinocytes are specialized cells found in the outer layer of the hair follicle. These cells play a crucial role in the growth and regeneration of hair, as they provide structural support and contribute to the formation of the hair shaft. For professionals, it's important to note that these keratinocytes are involved in the hair cycle's anagen (growth) phase and can be a focus in studies related to hair loss and treatments for conditions like alopecia.

research An osteopontin‐derived peptide inhibits human hair growth at least in part by decreasing fibroblast growth factor‐7 production in outer root sheath keratinocytes

19 citations , September 2019 in “British Journal of Dermatology”

This study found that a novel peptide, FOL-005, derived from osteopontin, significantly inhibited hair growth in human hair follicles both ex vivo and in vivo, suggesting potential as a treatment for unwanted hair growth.

research Progenitor cells expressing nestin, a neural crest stem cell marker, differentiate into outer root sheath keratinocytes

12 citations , July 2019 in “Veterinary Dermatology”

The study suggests that nestin-expressing progenitor cells can differentiate into outer root sheath keratinocytes in hair follicles, indicating distinct progenitors for different hair follicle and epidermal components.

research Sex Hormones and Antiandrogens Influence In Vitro Growth of Dermal Papilla Cells and Outer Root Sheath Keratinocytes of Human Hair Follicles.

12 citations , July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

research Sex hormones and antiandrogens influence in vitro growth of dermal papilla cells and outer root sheath keratinocytes of human hair follicles

9 citations , July 1993 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that the in vitro growth of hair follicle cells, particularly papilla cells and outer root sheath keratinocytes, is influenced by different concentrations of androgens and antiandrogens.

research Adenosine Promotes Human Hair Growth and Inhibits Catagen Transition In Vitro: Role of the Outer Root Sheath Keratinocytes

3 citations , November 2019 in “Journal of Investigative Dermatology”

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

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.

community Study on Sugar Intake on Male Pattern Hair Loss

19 upvotes 3 years ago

Excessive sugar and high-fat diets are linked to male pattern hair loss, with sweet beverages being a significant factor. Moderation in diet is advised, as diet alone may not fully prevent hair loss due to other factors like DHT sensitivity.

community Compressed part of research of theory of androgenic/anabolitic balance. AGA h-responders analytic. Theory of physio-metabolitic method of anti AGA treatment

in Research 865 upvotes 1 year ago

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.
