Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Adding human blood vessel cells to hair follicle germs may improve hair growth and quality.

Activating TRPV3 stops human hair growth.

Taxol damages hair growth cells, causing hair loss.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

Twisting hair weakens it, but strength can be recovered at low twist levels.

A new method helps understand hair shine and various products improve hair care.

Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

Dexpanthenol helps human hair follicle cells grow by preventing aging and death, and by supporting growth signals.

Hair follicle studies suggest that maintaining telomere length could help treat hair loss and graying, but it's uncertain if mouse results apply to humans.

UV light helped human hair transplants survive in mice without broad immunosuppression.

Injectable hydrogels are becoming increasingly useful in medicine for drug delivery and tissue repair.

The new microwell device helps grow more hair stem cells that can regenerate hair.

Creating fully functional artificial skin for chronic wounds is still very challenging.

Stem cells from hair follicles in a special gel show strong potential for bone regeneration.

Mesenchymal stem cells show promise for effective skin repair and regeneration.

Edelweiss extract can increase hair density and promote hair growth.

Alkaline Ceramidase 1 prevents early hair loss in mice by keeping hair follicle stem cells balanced.

Nutritional supplements may help improve hair growth in female pattern hair loss.

A new method using a microfluidic device can prepare hair follicle germs efficiently for potential use in hair loss treatments.

Researchers created a long-lasting mouse skin cell strain that may help with hair growth research and treatments.

Microneedles with extracellular vesicles show promise for treating various conditions with targeted delivery.

Carbon dots show promise for tissue repair and growth but need more research to solve current challenges.

The nanofibers effectively treated infected diabetic wounds by killing bacteria and aiding wound healing without toxicity.

Diamond nanoparticles can penetrate skin and reach hair follicles, useful for imaging applications.

Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

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.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.
