The enzymes Tet1, Tet2, and Tet3 are important for the development of hair follicles and determining hair shape by controlling hair keratin genes.

Gamma-rays exposure during the resting phase of hair growth can damage hair regeneration and color in mice.

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

Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.

Muscle around hair follicles controls hair loss by releasing a signal that causes cell death.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

A new method quickly and efficiently isolates hair follicle stem cells from adult mice, promoting hair growth.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

Human stem cells can help form hair follicles in mice.

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

The new patch made of cell matrix and a polymer improves wound healing and supports blood vessel growth.

Mice can regrow hair on wounds due to specific cell interactions and mechanical forces not seen in rats.

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

Hair follicles repair 3D injuries using a 2D healing process.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Fat under the skin releases HGF which helps hair grow and gain color.

Edelweiss extract can increase hair density and promote hair growth.

Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

GDNF helps grow hair and heal skin wounds by acting on hair stem cells.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Removing centrosomes from skin cells leads to thinner skin and stops hair growth, but does not greatly affect skin cell differentiation.

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.

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

The mTurq2-Col4a1 mouse model shows that cells can divide while attached to stable basement membranes during development.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.
