Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.

Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.

WNT signaling is crucial for skin development and healing.

Glehnia littoralis and Andrographis paniculata extracts can significantly boost hair growth.

The gene Ascl4 is not necessary for the development of hair, teeth, or mammary glands.

Two microRNAs affect hair follicle development in sheep by targeting specific genes.

Nanoparticle-based herbal remedies could be promising for treating hair loss with fewer side effects and lower cost, but more research is needed.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

Natural products may help treat hair loss by promoting hair growth with fewer side effects.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.

Hair follicle regeneration in skin grafts may be possible using stem cells and tissue engineering.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.

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

MED1 affects skin wound healing differently in young and old mice.

Poor maternal nutrition can lead to fewer wool follicles in Chinese Merino sheep.

The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.

Sildenafil, often used for erectile dysfunction, may help hair growth.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.

Wnt5a may slow down hair growth in mice.

Certain inhibitors applied to the skin can promote hair growth by maintaining a key hair growth signal.

Exosomes from dermal papilla cells help hair follicle stem cells grow and survive.
