This article describes the skin changes seen in acute and chronic graft-vs-host reactions after bone marrow transplantation, highlighting the potential for early recognition due to the visibility of these changes, but reports no new clinical results.

This study found that wound healing after scald burns in mice was slower in deeper burns, but the healing quality in second-degree deep scalds was similar to normal healing.

This study found that implanting hair follicle dermal sheath cells in rat skin wounds significantly accelerated wound contraction and healing compared to controls.

This review examines the roles of macrophages and fibroblastic cells in organ injury and repair, discussing their impact on outcomes ranging from regeneration to fibrosis, without presenting new clinical results.

This study found that a hydrogel containing icariin enhanced wound healing and hair-follicle regeneration in vivo by promoting M2 macrophage polarization and modulating the BMP pathway, with treated skin defects showing improved recovery and new hair follicle development compared to untreated defects.

In this case report, researchers described a rare instance of granuloma annulare in a six-year-old child mimicking alopecia mucinosa, highlighting the importance of clinicopathologic correlation in diagnosing dermatological conditions. Treatment with topical mometasone furoate led to a satisfactory improvement and complete resolution within seven months.

This study reported significant moderate-to-severe complications in two patients following synthetic hair fiber implantation, including recurrent infections, scalp issues, and granulomatous reactions, which were only resolved once the fibers were removed despite initial treatment attempts with antibiotics.

This case report describes an 80-year-old patient whose scalp wound healed by secondary intention, with unexpected hair regrowth observed at 180 days, suggesting hair neogenesis is possible even in older adults.

This study developed a composite hydrogel that delivered multiple proteins, enhancing skin wound healing by accelerating closure and promoting hair follicle regeneration.

This study found that dextran-based hydrogels promoted significant neovascularization and skin regeneration in mouse models of third-degree burns, without the need for additional growth factors or cells.

This case report describes a unique lesion in a 10-month-old girl, characterized by increased eccrine glands and hair follicles, leading to the proposed term "hybrid eccrine gland and hair follicle hamartoma".

This study found that hyaluronic acid increased the size and cell proliferation of mixed aggregates in a 3D culture model, indicating its role in human hair follicle germ-like structure formation without enhancing dermal papilla cell markers.

This paper proposes that GDNF signaling may enhance skin regeneration and hair follicle formation by influencing dermal fibroblast differentiation, particularly following injury.

Treating generalized granuloma annulare is difficult, with PUVA being the most effective option, but relapses are common.

In this case report, a 64-year-old Thai woman with a history of misdiagnosed eczema or folliculitis was ultimately found to have granular parakeratosis of the eccrine ostium, leading to significant symptom improvement once accurately diagnosed and advised to avoid excessive heat and moisture.

Trauma can cause fat inflammation and abnormal hair growth.

This article reviews skin regeneration and fibrosis, identifying key cellular and molecular players, and emphasizing the potential to manipulate the postwound environment to promote regeneration over fibrosis.

This study found that in female mice, softer, lightly crosslinked gelatin-based hydrogels promoted better wound healing with less scarring and inflammation compared to stiffer, heavily crosslinked hydrogels, affecting immune and stromal cell behavior.

In a rabbit model, this study found that the AMFIBHA skin substitute promoted wound healing and regeneration of skin structures in large-area third-degree burn wounds, suggesting potential clinical use.

This study found that although mature neutrophils and NETs are stimulated by a pro-regenerative cue, their presence actually hinders wound-induced hair follicle regeneration.

This letter to the editor presents two new cases of traumatic panniculitis with localized hypertrichosis and provides clinical considerations, but it does not report experimental findings.

In this study, researchers developed a GelMA-based gradient pH hydrogel that effectively reduced bacterial load and promoted fibroblast and endothelial cell proliferation, macrophage polarization, neovascularization, and hair follicle regeneration, offering a promising treatment for bacterially infected skin wounds.

In this study, oral acitretin therapy for psoriasis was associated with excess granulation tissue in the nail sulcus and noncicatricial universal alopecia.

This article reviews the complex process of wound repair, emphasizing recent microarray studies and proteomic analyses, but reports no new clinical results.

This study used single-cell RNA-sequencing data from mouse skin to reveal that fibroblasts show high transcriptional plasticity during wound healing, forming transient microniches early on and stratifying scar tissue into distinct molecular layers over time.

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

Granulomatous alopecia may be a distinct subtype of alopecia areata.

A patient with "strawberry gingivitis" improved after correct treatment for Granulomatosis with polyangiitis, highlighting the need for early diagnosis.

This study found that tissue-engineered skin using mouse fibroblasts successfully supported hair growth after grafting, but similar success was not observed using human fibroblast-derived tissue.

This article suggests that using cyanoacrylate adhesives may improve the cosmetic appearance of hair transplants by preventing graft elevation or cobblestoning, though no new research data was reported.
