Burn reconstruction improves with new techniques, materials, and tissue engineering.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

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.

This review explores the potential of using genetically-manipulated stem cells as both therapeutic agents and gene delivery vehicles for enhanced wound regeneration, but it reports no new clinical results.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.

This review discusses rodent models of alopecia areata and suggests they are crucial for understanding the autoimmune mechanisms and potential treatments but reports no new clinical results.

This study found that treating acute and chronic canine skin wounds with adipose-derived mesenchymal stem cells significantly improved healing and reduced inflammation, suggesting potential benefits for human wound care.

This review discusses the ethnobotanical uses and phytochemistry of Plumbago zeylanica L., highlighting its potential pharmacological benefits for conditions such as diabetes and cardiovascular disorders, but reports no new experimental findings.

This review examines non-surgical methods for rejuvenating the periorbital area and highlights the growing role of platelet-rich plasma, but it reports no new clinical findings.

This study investigated the effects of the herbal formulation DA-5512 on hair growth, finding that it significantly promotes dermal papilla cell proliferation and stimulates hair growth in mice while showing efficacy and safety in human trials compared to placebo and minoxidil (3%).

This study found that certain metabolites from the plants Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana may support hair follicle growth by promoting dermal papilla cell proliferation, supporting their traditional use in hair care.

This study provides evidence that long-term deregulation of the circadian rhythm in humans affects the regenerative properties of skin and hair precursor cells by altering clock pathway protein expression.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study found that the imidacloprid/flumethrin collar (Seresto®) is chemically compatible with major spot-on formulations and dermally and systemically safe for adult dogs and cats when used together.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

This study found that EGCG improved the integrity of skin grafts during cryopreservation, suggesting its potential usefulness for skin preservation, though the exact mechanism remains unclear.

In this study, activating TRPV1 nociceptors in mice skin stimulated dormant hair follicles and promoted hair growth through a mechanism involving dermal macrophages, fibroblasts, and neuropeptides, highlighting a new role for nociceptors in tissue recovery after injury.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This review evaluates the clinical use of composite dermal-epidermal skin substitutes, with a focus on advancements such as the "BioMask" for facial skin trauma, highlighting the potential of 3D bioprinting and bioengineered skin in improving wound treatment and reconstruction.

This study suggests that low-dose IL-2 and IL-15 may help restore immune tolerance in alopecia areata by maintaining Treg cell function, presenting a potential new treatment strategy.

In this study, the Peninsula Timerevert Needle was found to provide effective treatment for skin photoaging and acne scars with less pain and shorter treatment duration compared to EndyMed, although it caused more bleeding.

This study concluded that the CXCL12–CXCR4 signaling pathway significantly contributes to hair loss in androgenetic alopecia and alopecia areata by promoting inflammation and fibrosis, whereas inhibiting this pathway can restore hair growth and follicle health.

This study constructed a single-cell atlas of hair follicle cells from yaks and taurine cattle, revealing that differences in WNT signaling within dermal papilla cells may be key to the yak's adaptation to cold environments on the Qinghai-Tibet Plateau.

This narrative review examined skin-sparing techniques in gynecomastia surgery and found satisfactory thoracic remodeling with acceptable morbidity and reduced scarring, but acknowledged methodological differences that limit decisive conclusions.

This study found that a hair serum with plant-derived ingredients significantly reduced hair loss in women with chronic telogen effluvium over 16 weeks, and was well-tolerated, leading to improved hair characteristics and quality of life compared to a control group.
