IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.

Undariopsis peterseniana extract helps hair grow by activating certain cell growth pathways and could be a new treatment for hair loss.

Women's hair generally gets thinner and less dense starting in their mid-thirties, with hair loss becoming more common as they age due to both genetics and environment.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

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

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

Growth factors are crucial for hair development and could help treat hair diseases.

Human skin responds to light with protective mechanisms, but more research is needed to understand these processes and their implications for health and therapy.

The rat vibrissa follicle can quickly remodel its basement membrane during hair growth, affecting cell signaling and activity.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

Eating less can slow aging and help keep stem cells healthy by cleaning out damaged cell parts.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Laser therapy on human skin affects the HERC6 gene and related genes, influencing many cell processes and requiring careful safety measures.

Ovol2 is important for proper skin healing and hair growth.

Integrin alphavbeta6 is important for wound healing and hair growth, and blocking it may improve these processes.

Reactive oxygen species (ROS) influence hair growth by causing DNA damage, cell death, and changes in immune cells.

Temporary ROS production in cultured human hair follicles promotes growth and stem cell activation.

The study found that expanded skin regenerates similarly to normal skin, with 77 genes playing a role in the process.

Applying certain inhibitors to the skin can promote hair growth without harming cells.

The circadian clock affects skin stem cell behavior, impacting aging and cancer risk.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

TPA promotes hair growth by increasing stem cell activity and activating specific cell signals.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Increasing mir-302 turns human hair cells into stem cells by changing gene regulation and demethylation.

Muscles and nerves that cause goosebumps also help control hair growth.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

c-kit affects hair growth and color in alopecia areata and androgenetic alopecia.

Mechanical forces are crucial for shaping cells and forming tissues during development.
