The reconstructed skin model from hair follicles functions like human skin in processing chemicals and can be used to test ingredient safety.

α3β1-integrin is crucial for maintaining normal hair follicle shape and function but not needed for the development of the surrounding skin.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

CD4 is crucial for maintaining skin stem cell balance and aiding wound healing.

Skin RAGE levels are linked to inflammation and cell death.

Beta-catenin is crucial for skin cell growth, development, and cancer formation.

Activating Notch in adult skin causes T cells and neural crest cells to gather, leading to skin issues.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Different types of skin stem cells can change and adapt, which is important for developing new treatments.

Overexpressing the mineralocorticoid receptor in mouse skin causes skin thinning, early skin barrier development, eye issues, and hair loss.

Ift20 is essential for hair follicle function and skin cell movement.

TCDD speeds up skin barrier formation by increasing certain gene expressions.

The vitamin D receptor is essential for skin stem cells to grow, move, and become different cell types needed for skin healing.

Par3 protein is essential for skin cell balance and stability.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

The method increases stem-like cells for better skin regeneration.

Myc changes chromatin in stem cells, causing them to leave their niche.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

TAF4 is important for skin cell growth and helps prevent skin cancer in mice.

Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Embryonic and adult stem cells are valuable for improving skin grafts and cell therapy.

Human dermal fibroblasts help microvascular endothelial cells grow, but not vice versa.

Understanding embryologic layers improves skin disorder diagnosis and supports developing targeted therapies.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.
