Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

Stem cell therapy is a promising approach for hair regrowth despite potential side effects.

Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.

Improving the environment and cell interactions is key for creating human hair in the lab.

Both human platelet lysate and minoxidil can promote hair growth, but they affect different genes and cell survival rates.

Bioactive molecules show promise for improving skin repair and regeneration by overcoming current challenges with further research.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

Future research should focus on making bioengineered skin that completely restores all skin functions.

New effective scar treatments are urgently needed due to the current options' limited success.

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.

Hair in mammals likely evolved from glandular structures, not scales.

Using stem cell-enriched fat injections before hair transplant surgery can result in less hair loss and thicker hair.

Bone-forming cells grow well in 3D polymer scaffolds with 35 µm pores.

New treatments for hair loss, including a compound called "ALRV5XR", platelet-rich plasma, and Adult Stem Cell-based therapy, are showing promise, but more trials are needed for confirmation.

Injecting scalp tissue micrografts is a safe and effective treatment for hair loss after COVID-19.

Research on "hair cloning" for hair loss shows potential for hair thickening but has not yet achieved new hair growth in humans.

TLR2 helps control hair growth and regeneration, and its reduction with age or obesity can impair hair growth.

Special particles from skin cells can promote hair growth by activating a specific growth signal.

miR-140-5p in certain cell vesicles helps hair growth by boosting cell proliferation.

A peptide called DPS-1 helps human scalp cells grow and stimulates hair growth in mice.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Cyclosporine A helps hair grow by blocking a process that would otherwise cause hair cells to die.

BMP6 and Wnt10b control whether hair follicles are resting or growing.

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

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

Activating the Wnt/β-catenin pathway could lead to new hair loss treatments.

Dermal cells are key in controlling hair growth and could potentially be used in hair loss treatments, but more research is needed to improve hair regeneration methods.

The conclusion is that certain cell interactions and signals are crucial for hair growth and regeneration.
