Advanced human skin models improve drug development and could replace animal testing.

Skin has a larger surface area than thought, certain skin cells improve skin flap survival, better trials for skin conditions in children are needed, Stevens-Johnson syndrome rates vary by age and race, and better skin barrier function may reduce inflammation in the elderly.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

Sunlight exposure damages hair follicles, but certain stem cell-derived particles can reduce this damage and help with hair regeneration.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Stem cell and platelet-rich plasma therapies show promise for COVID-19 related hair loss, but more research is needed.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

3D bioprinting improves wound healing by precisely creating scaffolds with living cells and biomaterials, but faces challenges like resolution and speed.

The patch assay can create mature hair follicles from human cells and may help in hair loss treatments.

Non-surgical procedures can help reduce wrinkles and stimulate skin repair by understanding skin aging at the molecular level.

Researchers developed a new method to test hair growth drugs and found that adult cells are best for hair growth, but the method needs improvement as it didn't create mature hair follicles.

New methods to test hair growth treatments have been developed.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

Fat-related cells are important for initiating hair growth.

Skin cell-derived vesicles can help heal skin injuries effectively.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

New methods for skin and nerve regeneration can improve healing and feeling after burns.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

New treatments for hair loss show promise, including plasma, stem cells, and hair-stimulating complexes, but more research is needed to fully understand them.

MSCs and their exosomes may speed up skin wound healing but need more research for consistent use.

Stem cell therapy shows promise in improving burn wound healing.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Substance from human umbilical cord blood cells promotes hair growth.

Skin stem cells can help improve skin repair and regeneration.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Fat cells help recruit healing cells and build skin structure during wound healing.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.
