Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.

Microneedle arrays with nanotechnology show promise for painless drug delivery through the skin but need more research on safety and effectiveness.

The conclusion is that a new biopsy technique and humidity chamber help study skin mites better and suggest mite overpopulation may cause skin diseases.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.

A protein called IL-36γ causes skin side effects from certain cancer treatments when combined with a common skin bacteria.

Patient-derived melanocytes can potentially treat vitiligo by restoring skin pigmentation.

Fat stem cells from diabetic mice can help heal skin wounds in other diabetic mice.

The new CoQ10 gel protects mouse skin better against aging from UV light than the old gel.

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

Skin cells can help create early hair-like structures in lab cultures.

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

Urokinase, a type of protein, helps skin cells multiply faster, especially in newborn mice.

Melatonin affects skin and hair color and protects skin cells, with potential benefits for hair growth and skin health.

The protein Par3 is crucial for healthy skin, affecting the skin barrier, cell differentiation, and stem cell maintenance.

sPLA2-IIE is crucial for normal hair follicle structure and skin health.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

Age, smoking, and lower BMI increase facial wrinkles; men wrinkle more than women, except in old age; pale skin and certain hormonal factors can protect against wrinkles.

iPSC-derived stem cells on a special membrane can help repair full-thickness skin defects.

ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.

KLF4 is important for maintaining skin stem cells and helps heal wounds.

Skin lymphatic vessels are essential for hair growth.

Mice genetically modified to produce more CD109 in their skin had less inflammation and better healing with less scarring.

Yellow and orange colors are important for diagnosing certain skin conditions.

Telomere damage affects skin and hair follicle stem cells by messing up important growth signals.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Both human and animal-derived small extracellular vesicles speed up skin healing equally well.

Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.

Grouping certain skin cells together activates a growth pathway that helps create new hair follicles.

Using bioreactors, scientists can grow more skin stem cells that keep their ability to regenerate skin and hair.

Inhibiting AP1 in mice skin causes structural changes and weakens the skin barrier.
