Glossary Stem Cell Factor

protein crucial for stem cell survival and differentiation

Stem Cell Factor (SCF), also known as Kit Ligand, is a protein that plays a crucial role in the survival, proliferation, and differentiation of hematopoietic stem cells, which are the cells responsible for forming blood. SCF binds to the c-Kit receptor on the surface of these stem cells, activating signaling pathways that are essential for their function and maintenance. This factor is also important in other biological processes, including pigmentation, fertility, and the development of certain cell types in the immune system.

Stem Cell Factor/c-Kit Signaling in Normal and Androgenetic Alopecia Hair Follicles

research Stem cell factor/c-Kit signalling in normal and androgenetic alopecia hair follicles

39 citations , January 2008 in “Journal of Endocrinology”

This study found that in androgenetic alopecia, reduced stem cell factor production by dermal papilla cells may lead to decreased pigmentation in hair follicles.

research Interaction between stem cell factor and endothelin-1: effects on melanogenesis in human skin xenografts

27 citations , August 2006 in “Laboratory Investigation”

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

community Scalp Microneedling with Stemcell and Exohealer

149 upvotes 3 months ago

A user tried scalp microneedling with stem cells and exohealer in Korea for hair loss, costing $2.5k, and is awaiting results. Another user shared their experience using various growth factors and supplements, noting it improves existing hair but doesn't grow new hair, requiring monthly maintenance.

community Stem cells for hair, does it work?

in Technology 8 upvotes 9 months ago

Stem cell treatments for hair restoration can be effective, but results vary and depend on factors like the type of stem cells used and timing of treatment. PRP and exosomes have shown some success, while costs and effectiveness differ by location, with South Korea and Turkey offering more affordable options.

community Calecim (PTT-6) Advanced Hair System with Topical Exosomes and Growth Factors for Hair Growth

1 year ago

Calecim (PTT-6) Advanced Hair System is a 6-week hair restoration product using stem cell-derived ingredients to stimulate hair growth. Users are skeptical, calling it overpriced and ineffective, suggesting alternatives like LLLT devices or PRP treatments.

community Stem cell therapy for thicker hair

9 upvotes 3 years ago

Stem cell therapy for hair thickening is discussed, with some users reporting positive results from exosome treatments and others questioning the legality and effectiveness of stem cell claims in the USA. Users also mention using finasteride, minoxidil, PRP, and mesoderm therapy for hair loss.

community How Does Exosome Therapy Work for Hair Loss?

in Research/Science 5 upvotes 2 years ago

Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.
