Technique creates 3D cell spheroids for hair-follicle regeneration.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Vitamin D receptor is crucial for starting hair growth after birth.

Mice without Vitamin D receptors have hair growth problems because of issues in the hedgehog signaling pathway.

The research provides specific measurements for hair follicles that can improve hair transplant and regeneration techniques.

Maintaining the right amount of retinoic acid is crucial for healthy hair and skin.

Estrogens generally inhibit hair growth and improve skin quality, but their exact effects on hair follicles are complex and not fully understood.

Different skin stem cells help heal wounds, with hair follicle cells becoming more important over time.

Bcl-2 overexpression protects against UVB damage but worsens hair loss from chemotherapy.

α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.

Researchers found a way to create cells from stem cells that act like human cells important for hair growth and could be used for hair regeneration treatments.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

Engineered skin substitutes can grow hair but have limitations like missing sebaceous glands and hair not breaking through the skin naturally.

S100A3 protein is crucial for hair shaft formation in mice.

Ephrins slow down skin and hair follicle cell growth.

Macrophages help hair growth after injury through CX3CR1 and TGF-β1.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.

Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.

CIP/KIP proteins help stop cell division and support hair growth.

Steroids, particularly estrogens and 5α-reductase inhibitors, affect blood vessel-related hair growth processes in hair follicle cells.

The experiment showed that human skin grown in the lab started to form early hair structures when special cell clusters were added.

Smad4 is important for healthy hair follicles because it helps produce a protein needed for hair to stick together and grow.

Wnt-10b is important for starting hair growth and developing hair follicles.

Certain transporters are found in human hair follicles and may affect hair growth and loss.

Nuclear Factor I-C is important for controlling hair growth by affecting the TGF-β1 pathway.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

Cultured dermal papilla cells can regenerate hair follicles and sustain hair growth.
