This study reported that a newly developed hydrogel patch, designed to recruit regulatory T cells through ROS-triggered release of CCL22, improved wound healing and hair follicle regeneration in a diabetic mouse model by scavenging ROS, thereby protecting Tregs and suppressing Th17 cells.

This study found that using retroauricular full-thickness skin grafts in vestibuloplasty contributed to successful cosmetic and functional outcomes in dental implant rehabilitation for patients with mandibular gunshot injuries.

This study concluded that using an erbium:YAG laser for calvarium trepanation and granulation tissue induction is comparable to the rose head burr, offering a beneficial alternative method.

This article reviews the current status of oral retinoids in dermatology and reports no new clinical findings.

In this study, decellularized human amniotic membrane was found to promote wound healing and reduce scar formation in rats with full-thickness skin defects, compared to traditional clinical treatments.

Antiyeast treatments work better for seborrheic dermatitis than steroids, and other findings include increased skin bacteria under plastic wrap, a nasal cell defect in Staphylococcus aureus carriers, quick resolution of certain skin reactions, high rubber latex allergy in spina bifida patients, and glyceryl monopentadecanoate's effectiveness for male hair loss.

This research observed that 3D electrospun micro/nanofibrous sponges, without using chemical crosslinking agents, supported enhanced cell growth, vascularization, and skin regeneration in diabetic rats compared to 2D fiber membranes, making them promising for 3D tissue regeneration.

This study revealed that frizzled 3 can fully rescue polarity defects in frizzled 6-null mice, while frizzled 6 can partially rescue defects in frizzled 3-null mice, highlighting conserved signaling roles in these proteins.

This study found that a new SIS-PEG sponge promoted rapid skin defect healing in mice and showed potential for reconstructing reconstituted skin with regenerated hair.

This study observed that tissue-engineered skin, using VEGF165 gene-modified cells embedded in astragalus polysaccharide-containing 3D printed scaffolds, enhanced early vascularization, and collagen and hair follicle regeneration, leading to improved skin repair in nude mice with full skin defects.

This study explored recent advancements in 3D bioprinting for head and neck defects, highlighting how bioinks and scaffolds may improve treatment customization and functionality by mimicking native tissue features. The research also examined challenges like biocompatibility and regulatory requirements on the path to clinical use.

This study found that using engineered skin with PGA-collagen scaffolds, combined with hair follicle stem cells and other cell types, effectively repaired full-thickness skin defects in nude mice.

This study reports that tissue-engineered skin using ES cell-derived epidermal stem cells and collagen sponge successfully healed full thickness skin defects in mice, forming epidermis and structures resembling glands and hair follicles.

In this study, deleting the transcriptional pause factor Nelfb in mouse preadipocyte lineages led to defective dermal fat formation and lethal outcomes, while interventions targeting Pparg could rescue adipocyte differentiation and promote dermal white adipose tissue formation, underscoring Nelfb's critical role in adipogenesis.

This review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

This narrative review discusses the role of injectable biomaterials in dental tissue regeneration, highlighting their suitability for treating small, hard-to-access oral defects compared to pre-formed scaffolds, and explores the potential use of nanofibers in dental applications.

This study found that an acellular dermal matrix derived from tilapia skin significantly accelerated wound healing and improved tissue regeneration quality in mouse and pig models compared to a commercial porcine-derived matrix, suggesting its potential as a safe, cost-effective bioscaffold for skin repair.

This study found that notch1 signaling is severely impaired in hidradenitis suppurativa patients with or without NCSTN or other gamma-secretase gene mutations, highlighting a canonical defect at the lesional tissue level.

This study found that HFV70 cryogels, made from Flammulina velutipes extract and hydroxyethyl cellulose, effectively promoted rapid hemostasis and tissue regeneration in full-thickness skin defects in rats, demonstrating improved hemocompatibility, cytocompatibility, antimicrobial, and antioxidant properties.

This article reviews surgical techniques for addressing scalp defects and highlights hair restoration as a cosmetic improvement strategy, but it reports no new clinical results.

In an animal study with a skin defect model, this research reported that curcumin-loaded hydrogels made from recombinant humanized collagen and an eco-friendly crosslinker enhanced wound repair by promoting angiogenesis, granulation tissue formation, and hair follicle neogenesis, while providing antioxidant benefits.

This study found that the "flying-wings" expanded scalp flap technique effectively restored hemiscalp defects in children following burns, achieving pleasing aesthetic results and proper hair growth direction with minimal complications.

This research review explores an algorithmic approach to scalp reconstruction, emphasizing the importance of considering defect location, size, and local scalp anatomy in optimizing cosmetic and functional surgical outcomes.

In this study, mice engineered to express human EGFR showed tissue-specific growth defects and neurodegeneration rescue, but developed severe heart issues and accelerated bone cell differentiation.

This research found that LSE transplantation positively affects wound healing by promoting granulation tissue growth and minimizing cosmetic defects in ischemic non-healing wounds during preclinical studies. Additionally, the proposed smoothing coefficient helps assess the degree of wound bed filling with developing tissue.

This study found that combined loss of Atr and p53 in adult mice led to severe tissue degeneration and delayed regeneration due to the accumulation of highly damaged cells.
