Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

The review concluded that keeping the hair-growing ability of human dermal papilla cells is key for hair development and growth.

3D microenvironments in microwells improve hair follicle stem cell behavior and hair regeneration.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

A new hydrogel with stem cells from human umbilical cords improves skin wound healing and reduces inflammation.

The hydrogel with silver and mangiferin helps heal wounds by killing bacteria and aiding skin and tissue repair.

Germany recognizes skin cancer from UV exposure as an occupational disease, emphasizing prevention and care for affected workers.

The method allows for 3D tracking of hair follicle stem cells and shows they can regenerate hair for up to 180 days.

Only skin melanocytes, not other types, can color hair in mice.

AP-2α and AP-2β proteins are essential for healthy adult skin and hair.

A protein from certain immune cells is key for new hair growth after skin injury in mice.

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.

Short-chain fatty acids from *Cutibacterium acnes* cause skin inflammation, contributing to acne.

Prolactin affects the production of different keratins in human hair, which could lead to new treatments for skin and hair disorders.

Nanocarrier-loaded gels improve drug delivery for cancer, skin conditions, and hair loss.

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

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

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

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

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.

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

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

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

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

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

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

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

Researchers developed a scaffold that releases a healing drug over time, improving wound healing and skin regeneration.

A specific group of slow-growing stem cells marked by Thy1 is crucial for skin maintenance and healing in mice.

Chronic stress in mice changes skin metabolism and gene expression, leading to hair loss.
