Did you mean Bulge Region?

Glossary Bulge Region

specific area in hair follicle housing stem cells

The bulge region is a specific area located in the outer root sheath of a hair follicle. It contains a reservoir of stem cells that are crucial for hair growth and regeneration. These stem cells can also contribute to the repair of the skin and other tissues, making the bulge region essential for both hair health and overall skin maintenance.

$Human Keratinocytes Derived from the Bulge Region of Hair Follicles Are Refractory to Differentiation$

research Human keratinocytes derived from the bulge region of hair follicles are refractory to differentiation

8 citations , April 2009 in “International journal of oncology”

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

research In vitro identification of a stem cell population from canine hair follicle bulge region

5 citations , December 2017 in “Tissue and cell/Tissue & cell”

This study observed that skin stem cells in dogs could be identified using CD34 and CD200 markers, although further refinement in isolation and cultivation methods is needed for better identification.

research Involvement of the bulge region with decreased expression of hair follicle stem cell markers in senile female cases of alopecia areata

20 citations , December 2010 in “JEADV. Journal of the European Academy of Dermatology and Venereology/Journal of the European Academy of Dermatology and Venereology”

This study found that selective downregulation of CD200 in the bulge area might contribute to unusual bulge involvement in a subset of alopecia areata cases.

Cells Within the Bulge Region of Mouse Hair Follicle Transiently Proliferate During Early Anagen: Heterogeneity and Functional Differences of Various Hair Cycles

research Cells within the bulge region of mouse hair follicle transiently proliferate during early anagen: heterogeneity and functional differences of various hair cycles

130 citations , January 1994 in “Differentiation”

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

research Isolation, Cultivation, and Morphological Characteristics of Hair Follicle Adult Stem Cells in the Bulge Region in Mouse and Human

1 citations , January 2020 in “Microscopy research”

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

community UVA researchers discovered stem cells that plays a crucial role in hair growth - We are closer than ever to the cure!

281 upvotes 1 year ago

Researchers at the University of Virginia discovered a new group of stem cells in hair follicles that could potentially restore hair growth. The findings suggest that activating these stem cells might offer a new way to combat hair loss, though practical treatments are still years away.

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 Microneedling depth. Does one length fit all areas of the scalp? Maybe not.

55 upvotes 4 years ago

Microneedling depth should be customized based on hair type and scalp area, with many users finding 0.5-0.6mm effective for miniaturized hairs to avoid damage. Users report varying pain levels and results, with some preferring shorter needle lengths and others using longer ones like 1.75mm for scalp health and density improvement.
