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

Skin can heal wounds without hair follicle stem cells, but it takes a bit longer.

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.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Macrophages are vital for skin healing, hair growth, salt balance, and cancer defense.

Fat cells are important for tissue repair and stem cell support in various body parts.

The microenvironment, especially mechanical forces, plays a crucial role in hair growth and could lead to new treatments for hair loss.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive stomach cancer.

Deleting Smad4 and PTEN genes in mice causes rapid, invasive forestomach cancer.

Hormones affect skin aging, and treatments targeting hormonal balance may improve skin health.

The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.

Finasteride boosts stem cell signals for hair growth.

Different miRNAs in Rex rabbit skin affect cell processes and hair growth.

Hair follicles have a more inactive cell cycle than other skin cells, which may help develop targeted therapies for skin diseases and cancer.

Scientists identified a unique type of human skin stem cell that could help with tissue repair.

Hair follicle stem cells can change their role to ensure proper hair development.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

The Hairless gene is crucial for healthy skin and hair growth.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Certain signals are important for reducing specific chemical markers on hair follicle stem cells during rest periods, which is necessary for healthy hair growth.

Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.

The document concludes that skin stem cells are important for hair growth and wound healing, and could be used in regenerative medicine.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Adipose-derived stem cells show potential for skin rejuvenation and wound healing but require more research to overcome challenges and ensure safety.

The protein CTCF is essential for skin development, maintaining hair follicles, and preventing inflammation.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Fat cells help recruit healing cells and build skin structure during wound healing.
