Glossary Epithelial Stem Cells

cells that regenerate and repair skin and hair follicles

Epithelial Stem Cells are a type of stem cell found in the epithelial tissues, which line the surfaces and cavities of organs and structures throughout the body, including the skin and hair follicles. These cells have the unique ability to self-renew and differentiate into various specialized cell types, playing a crucial role in tissue repair, regeneration, and maintaining the integrity of the epithelial layers.

research Lichen planopilaris is characterized by immune privilege collapse of the hair follicle's epithelial stem cell niche

220 citations , June 2013 in “The Journal of Pathology”

This study found that immune privilege collapse in the hair follicle bulge and associated immune responses may contribute significantly to the pathogenesis of lichen planopilaris, suggesting a potential autoimmune basis for the disease.

research Epithelial-Mesenchymal Micro-niches Govern Stem Cell Lineage Choices

214 citations , April 2017 in “Cell”

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

research 09-P006 Epithelial–mesenchymal interactions promote hair follicle neogenesis and a new stem cell niche in adult corneal epithelium

August 2009 in “Mechanisms of Development”

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

research The Epithelial Stem Cell Niche in Skin

9 citations , January 2017 in “Elsevier eBooks”

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

research Tooth, hair and claw: Comparing epithelial stem cell niches of ectodermal appendages

14 citations , February 2014 in “Experimental Cell Research”

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

community DHT Isn’t the Only Factor in Hair Loss and That Might Be the Key to a Real Cure

373 upvotes 6 months ago

Hair loss involves more than just DHT, with genetic factors like TRPS affecting hair follicles. Treatments such as Amplifica's AMP-601 and AMP-303 target stem cells for potential hair growth solutions.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community Prolactin the Cause of Hair Loss? ABS-201 the Cure?

29 upvotes 2 months ago

Prolactin may contribute to hair loss, but targeting its receptor won't cure androgenetic alopecia. ABS-201 could be a useful alternative or adjuvant therapy, similar to JAK inhibitors, but not more effective than HMI-115.

community Adipocyte lipolysis activates epithelial stem cells for hair regeneration through fatty acid metabolic signaling

23 upvotes 10 months ago

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

community Researchers working on ways to regenerate lost hair from stem cells identified a recipe for normal hair regeneration in the lab. “A method for cyclical regeneration of hair follicles from hair follicle stem cells and will help make hair follicle regeneration therapy a reality in the near future.”

263 upvotes 5 years ago

Hair loss treatments like finasteride, minoxidil, and hair transplants have side effects and limitations. There is hope for future advancements in stem cell therapy and hair follicle regeneration, though skepticism about their effectiveness and timeline persists.
