Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Oxidative stress contributes to hair graying and loss as we age.

Fat cells in the skin help start healing and form important repair cells after injury.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.

Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Female Pattern Hair Loss affects women's self-esteem and needs more research for better treatment.

FOXO1 is important for wound healing, but its dysfunction in diabetes can slow the healing process.

Asiasari radix extract promotes hair growth and increases protein synthesis and cell proliferation.

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

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Certain genes control the color of human hair by affecting pigment production.

PDRN helps repair tissue and improve wound healing with a high safety profile.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

Sophora flavescens extract may help hair grow by affecting growth factors and blocking a hair-related enzyme.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

Electrospun nanofibers show promise for enhancing blood vessel growth in tissue engineering but need further research to improve their effectiveness.

Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.

PRP treatment may stimulate hair growth by promoting blood vessel formation, increasing growth factors, and preventing cell death.

Certain signals and genes play a key role in hair growth and regeneration, and understanding these could lead to new treatments for skin regeneration.

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