Did you mean Cell Aggregates?

Glossary Cell Aggregates

groups of cells that adhere together forming a mass

Cell aggregates, also known as cell clusters, are groups of cells that adhere to each other, forming a mass. These aggregates can occur naturally in the body, such as in the formation of tissues and organs, or can be created in a laboratory setting for research purposes. In the context of hair and alopecia, cell aggregates might be studied to understand how hair follicles develop and how they can be regenerated or repaired.

The Enhancement of Dermal Papilla Cell Aggregation by Extracellular Matrix Proteins Through Effects on Cell–Substratum Adhesivity and Cell Motility

research The enhancement of dermal papilla cell aggregation by extracellular matrix proteins through effects on cell–substratum adhesivity and cell motility

44 citations , June 2009 in “Biomaterials”

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

research Decision letter: Hair follicle dermal condensation forms via Fgf20 primed cell cycle exit, cell motility, and aggregation

April 2018

This study found that fibroblast growth factor 20 (Fgf20) orchestrates the movement and behavior of dermal fibroblasts, directing their formation into dermal condensates during hair follicle development in mice.

research The effect of ovine secreted soluble factors on human dermal papilla cell aggregation

3 citations , January 2016 in “International Journal of Trichology”

This study found that soluble factors secreted by ovine dermal papilla cells enhance the aggregative behavior of human dermal papilla cells, potentially improving their follicle-inductive properties for hair replacement therapy.

community I built a tracker for every hair loss treatment in clinical development

in Research/Science 92 upvotes 8 months ago

A user created a tracker for hair loss treatments in clinical development, including compounds like Dermaliq, RU58841, and Pyrilutamide. The tracker updates with new information and allows filtering by conditions like androgenetic alopecia (AGA) and alopecia areata (AA).

community Cell senescence-targeted treatment for hair loss, has anyone tried any products/enzymes etc. that use this theory

5 upvotes 1 year ago

DHT causes hair loss by driving cells into senescence, and a polyphenol in black chokeberry may reverse this. A product using this theory is being considered for use alongside finasteride, minoxidil, and microneedling.

community Has anyone here actually undergone experimental (grey market) hair cell therapy/follicle cloning?

7 upvotes 5 months ago

Hair cell therapy and follicle cloning are still in experimental stages, with treatments like hair multiplication and regenerative hair therapy being marketed but not yet proven to create unlimited new follicles. There is skepticism about the effectiveness and legitimacy of these treatments, with some considering them scams.

community What do you guys think of stem cell hai restoration?

10 upvotes 8 months ago

Stem cell hair restoration lacks scientific evidence and is often considered a scam. Effective hair loss treatments include hair transplants, Minoxidil, and Finasteride, but stem cell treatments are not proven.

community Stem cell hair transplant? Any progress?

4 upvotes 1 year ago

Stem cell hair transplants are not yet viable, and users suggest traditional treatments like Minoxidil, finasteride, and hair transplants. Some mention verteporfin but note its alcohol restrictions.
