In 1989, the Regional Burn Center of the Children's Hospital Medical Center of Akron, Ohio, switched to use of commercially produced cultured epidermal autograft (CEA) from cultured cells that had been grown in the institution's own laboratories. CEA has the advantage of producing the quantity of grafts that are needed from the original biopsy specimen. Clinical experience with 10 patients has demonstrated an average of 72% "take" with approximately 1309 grafts. Arms, legs, and anterior trunk are the preferred sites for coverage. Patient/family education is an integral component of the CEA regimen; a structured educational program begins immediately. The cooperation of both patient and family is often a critical factor in successful grafting. Usually one to two biopsy specimens from the groin or the axilla are sent for culturing. The patient receives standard burn care while cultured tissue is grown, which includes physical therapy and splinting. Early excision, temporary coverage with cadaver skin, topical antibiotics, graft protection, and pain control are keys to success. Physical therapy and splinting are delayed until after removal of the graft backing, which usually occurs 10 to 12 days after CEA is applied.

Wound healing is a highly coordinated process driven by intricate molecular signaling and dynamic interactions between diverse cell types. Nod-like receptor pyrin domain-containing protein 3 (NLRP3) has been implicated in the regulation of inflammation and tissue repair; however, its specific role in skin wound healing remains unclear. This study highlights the pivotal role of NLRP3 in effective skin wound healing, as demonstrated by delayed wound closure and altered cellular and molecular responses in NLRP3-deficient (NLRP3) mice.

Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

Introduction: Systemic sclerosis is a complex disease characterized by the fibrosis and vasculopathy.
Aim: We aimed to assess scleroderma by examining involucrin, an early terminal differentiation marker of epidermal keratinocytes.
Material And Methods: Immunolocalization of involucrin was performed in healthy controls and patients with scleroderma lesions by using an immunofluorescence (IF) assay.

Superficial mycoses are characterized by the infection of keratinized tissues such as the epidermis, hair, and nails. A 52-year-old woman from Hainan Province, China is reported in this study. The patient presents with large erythematous scales on her head, face, and disfigured nails over a 2-year period.

The bioengineering of vascular networks is pivotal to create complex tissues and organs for regenerative medicine applications. However, bioengineered tissues comprising an arterial and venous plexus alongside a lymphatic capillary network have not been explored yet. Here, scRNA-seq is first employed to investigate the arterio-venous endothelial cell marker patterning in human fetal and juvenile skin.
