Eating fewer calories may slow aging and removing old cells can increase lifespan in mice.

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

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Engineered exosomes with EGF and FGF improve hair growth in mice with hair loss.

Recombinant keratins can form useful structures for medical applications, overcoming natural keratin limitations.

The volumes provide comprehensive guidance on aesthetic and reconstructive head and neck surgery.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Special fiber materials boost the healing properties of certain stem cells.

Peptide hydrogels heal burn wounds faster and better than standard dressings.

Biopolymeric composites need advanced properties for better use in medicine and healing.

Wnt signaling is crucial for skin wound healing and reducing scars.

Dental pulp stem cells can help heal skin and mucosal wounds effectively.

Androgenetic alopecia treatments are becoming more personalized and include new therapies like topical antiandrogens and regenerative strategies.

Platelet-rich fibrin speeds up burn wound healing in rabbits.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

Genetically-altered adult stem cells can help in wound healing and are becoming crucial in regenerative medicine and drug design.

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

Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.

Scaffold-based strategies show promise for regenerating hair follicles and teeth but need more research for clinical use.

Chitosan hydrogels are promising for repairing blood vessels but need improvements in strength and compatibility.

Organoids can revolutionize medicine by modeling diseases and aiding in personalized treatments.

The amnion bilayer dressing improved healing and reduced scarring in full-thickness burns.

Sponges made of soy protein and β-chitin with human cells from hair or fat can speed up healing of chronic wounds.

Innovative methods are reducing animal testing and improving biomedical research.

Micronized-gingival connective tissues are safe and may help regenerate soft tissue around dental implants.
