Glossary Progenitor Cells

cells that can differentiate into specific cell types but are more limited than stem cells

Progenitor cells are a type of cell that has the capacity to differentiate into a specific type of cell but is more limited than a stem cell. Unlike stem cells, which can divide indefinitely and become any cell type, progenitor cells are already on the path to becoming a particular kind of cell and can only divide a limited number of times. They play a crucial role in tissue development and repair, including in the regeneration of hair follicles.

Post-Transcriptional Regulation of Keratinocyte Progenitor Cell Expansion, Differentiation, and Hair Follicle Regression by miR-22

research Post-transcriptional Regulation of Keratinocyte Progenitor Cell Expansion, Differentiation and Hair Follicle Regression by miR-22

52 citations , May 2015 in “PLOS Genetics”

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

community Anyone here have a lot of knowledge on hair follicle stem cells and progenitor cells for PP405?

in Chat 4 upvotes 8 months ago

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

community New Hair Loss Cure: AMP-303 Is Back. It’s what PP405 should have been.

7 upvotes 5 months ago

AMP-303 and AMP-601 are new hair loss treatments targeting dermal papilla cells, with AMP-303 showing early efficacy in transitioning vellus hairs to terminal hairs after one injection. Further clinical trials are planned, and these treatments are seen as promising due to their biologic approach and less frequent application compared to daily treatments.

community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

community A Theory on Why Microneedling Works

175 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
