Did you mean progenitor cell populations?

GlossaryProgenitor Cells (progenitor cell populations)

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.

community My Theory Of Androgenic Alopecia

in Research/Science 19 upvotes 3 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 PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

in Research/Science 1 month 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 A Theory on Why Microneedling Works

170 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.
