This review discusses various surgical techniques for rejuvenating the aging upper face, focusing on the assessment of individual structures and their relationships, but it reports no new clinical results.

This review evaluates neck rejuvenation techniques, including cervical rhytidectomy, and discusses potential surgical complications, without presenting new clinical findings.

This study suggests that cultured human hair follicle cells can potentially recreate epidermis and produce bioengineered hair follicles in a GMP cell factory for regenerative therapy in alopecia.

In this study, Flii overexpression in mice enhanced fingertip regeneration and nail formation after both distal and proximal amputations, suggesting a role in digit and hair follicle regeneration possibly involving Wnt signaling.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

In this study, ultrasound was found to alter the distribution of fibronectin in collagen hydrogels, leading to enhanced microtissue formation, suggesting potential applications in tissue engineering.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

This study found that injectable gelatin/metal/tea polyphenol double nanonetworks significantly accelerated wound healing in diabetic wounds by enhancing cell migration and providing anti-inflammatory and antioxidant properties, without detectable cytotoxicity in tests.

In a study on mice, cow placenta extract showed strong antioxidant activities and reduced collagen damage, suggesting it could help delay skin aging caused by D-galactose.

In this study, researchers developed a silk fibroin-based hydrogel with added curcumin and pluronic F127, which displayed antibacterial properties against Methicillin-resistant Staphylococcus aureus and showed potential for skin tissue regeneration, without cytotoxicity.

This review discusses the roles and mechanisms of glycosaminoglycans in wound healing and presents challenges and potential applications for GAG-based biomaterials without reporting new experimental results.

This review discusses the characteristics and potential applications of epidermal stem cells in dermatology, without providing new clinical results.

This study found that cells from the upper hair follicle exhibited more active growth compared to other segments in vitro, suggesting their potential as a source of hair follicle stem cells.

This study found that the prenatal skin development in Red Sokoto goats undergoes significant morphological changes across gestational stages, which may be important for their adaptation and thermoregulation after birth.

In this study, researchers developed a DNA/GelMA-based cryogel platform that uses phototherapy to combat MRSA infection and promote scarless wound healing, showing enhanced bactericidal activity, tissue regeneration, and anti-inflammatory effects in vivo, suggesting a promising approach for treating infected skin wounds.

This perspective reviews enzyme-instructed self-assembly (EISA) as a conceptual framework for supramolecular chemical biology, emphasizing its innovative role in developing adaptive biomaterials and synthetic cellular machines without providing new experimental results.

This study found that in atrophic acne scars, inflammation infiltrates the pilosebaceous unit over time, affecting resident stem cells and hindering the normal regeneration of the epidermis and adnexal structures, leading to scarring.

In this study, a spayed adult female dog with recurrent vaginitis and cystitis due to bone structures in the vaginal canal was successfully treated with manual removal and medication.

New materials and methods could improve skin healing and reduce scarring.

This study found that a nanoparticle-in-nanofiber system significantly accelerated wound healing in rats by promoting angiogenesis and tissue regeneration more effectively than a commercial wound dressing.

Long-term use of a certain medication can worsen erectile function in aged rats by damaging penile muscle cells.
