Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Fat stem cells from diabetic mice can still help heal wounds.

Skin stem cells can help improve skin repair and regeneration.

Ezh2 controls skin development by balancing signals for dermal and epidermal growth.

Markers CRABP1, Nestin, and Ephrin B2 are present in skin cancer environments and may influence their development.

Prominin-1 expressing cells in the dermal papilla help regulate hair follicle size and communication but don't aid in skin repair.

SUN11602 and ONO-1301 could help in skin healing and creating artificial skin.

Hair growth medium helps heal wounds and regrow hair in mice.

Human dermal stem cells can become functional skin pigment cells.

Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.

Cell-based models help test if cosmetic ingredients really work for hair growth and skin health.

A hydrogel made from pig fat helps wounds heal faster by regenerating skin fat cells.

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

Scarless healing is complex and influenced by genetics and environment, while better understanding could improve scar treatment.

Certain circular RNAs are crucial for wool growth and curvature in goats.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

Tiny particles called extracellular vesicles show promise for treating skin conditions and promoting hair growth.

A special stem cell fluid can speed up wound healing and hair growth in mice.

Adenosine can help treat hair loss by promoting hair growth.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Fat-related cells are important for initiating hair growth.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Colchicine can inhibit hair growth by affecting cell activity and protein expression in hair follicles.

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.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.
