Keratin is crucial for keeping skin cells healthy and its changes can lead to diseases and affect cell behavior.

Cell size controls when stem cells divide.

Actinic keratosis is a sun-induced skin condition that can potentially turn into skin cancer and requires various treatments to prevent this.

A specific enzyme is essential for proper hair follicle stem cell development and healthy skin.

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

Surgical repigmentation can permanently restore color to white hair in vitiligo patients.

Visible light can damage skin and most sunscreens don't block it well; more research is needed on its effects and protection methods.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Skin stem cells help maintain skin health, grow hair, and heal wounds.

A disease causing skin issues in young adult German short-haired pointers is hereditary, with most affected dogs not responding to treatment.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

New chemotherapy drugs cause skin side effects, but treatments like minocycline and tetracycline can help reduce them.

Scientists developed a method to grow human fetal skin and digits in a lab for 3-4 weeks, which could help study skin features and understand genetic interactions in tissue formation.

Apoptosis is crucial for healthy skin and treating skin diseases.

CIP/KIP proteins help stop cell division and support hair growth.

Keratin genes change gradually during skin cell development and should be used carefully as biomarkers.

Keratin gene expression helps understand different types of skin cells and their development, and should be used carefully as biological markers.

Hair follicles protect melanocytes from sun damage, helping them replenish skin.

Actinic keratosis is a sun-induced skin condition that can potentially turn into skin cancer and requires treatment to prevent malignancy.

Any drug can cause skin reactions, but antibiotics, NSAIDs, and psychotropic drugs are more common, with some reactions being life-threatening.

Some chemicals and drugs can cause hair loss, which usually grows back after stopping the treatment.

Hamilton scale imprecise, hair shaft diameter decreases, stem cell transplant regrows hair, ECP ineffective for alopecia areata universalis.

The cause of alopecia areata is likely a mix of genetics, immune system issues, and environmental factors, with more research needed to understand it fully.

Better supportive care is needed to manage chemotherapy side effects.

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.

Activating a protein called β-catenin in adult skin can make it behave like young skin, potentially helping with skin aging and hair loss.

Epidermal stem cells create and maintain skin structures like hair and nails through specific signaling pathways and vary by location and function.

Wnt signaling helps regenerate hair follicles by affecting how skin cells sense and respond to mechanical forces.

BMAL1 controls skin cell growth and UV damage risk, peaking at night.

Hair follicles help skin immune recovery after UVB exposure.
