Cutaneous wound healing is a normal physiological process and comprises different phases. Among these phases, angiogenesis or new blood vessel formation in wound tissue plays an important role. Skin is richly supplied by sympathetic nerves and evidences indicate the significant role of the sympathetic nervous system in cutaneous wound healing. Dopamine (DA) is an important catecholamine neurotr...

Wound healing is a complex homeostatic response to injury that engages numerous cellular activities, processes, and cell-to-cell interactions. The complement system, an intricate network of proteins with important roles in immune surveillance and homeostasis, has been implicated in many physiological processes; however, its role in wound healing remains largely unexplored. In this study, we emp...

OBJECTIVES/HYPOTHESIS To determine if the intravascular delivery of mesenchymal stem cells improves wound healing and blood perfusion to postischemic cutaneous flap tissues. STUDY DESIGN Randomized controlled study. METHODS A murine model of a cutaneous flap was created based on the inferior epigastric vessels. Mice (n = 14) underwent 3.5 hours of ischemia followed by reperfusion. Bone marr...

Burns and other severe skin injuries alter cutaneous perception of pain, temperature, and touch. During skin wound healing, peripheral nerve regeneration can occur from nerve endings of the wound bed, however, a functional recovery after an injury is often not sufficient due to scar formation or impaired wound healing.

Diabetics frequently suffer from chronic, nonhealing wounds. Although bacterial colonization and/or infection are generally acknowledged to negatively impact wound healing, the precise relationship between the microbial community and impaired wound healing remains unclear. Because the host cutaneous defense response is proposed to play a key role in modulating microbial colonization, we longitu...

We present a 54-year old man with a pulmonary infectious cavity continuing to a cutaneous fistula. Before he was admitted to our hospital, he had undergone open-window surgery for a left thoracic empyema due to the rupture of pulmonary suppuration of the left upper lobe. He had then undergone thoracoplasty with the plombage of the cavity using left pectoralis major muscle. However, this procedu...

BACKGROUND Adipose-derived stem cells (ASCs) are mesenchymal stem cells that have recently been applied to tissue repair and regeneration. Keratinocytes and dermal fibroblasts play key roles in cutaneous wound healing. OBJECTIVE We investigated the paracrine effects of ASCs on HaCaT cells (i.e., immortalized human keratinocytes) and human dermal fibroblasts to explore the mechanism of the eff...

Wnt/β-catenin signaling plays important roles in cutaneous wound healing and dermal fibrosis. However, its regulatory mechanism has not been fully elucidated, and a commercially available wound-healing agent targeting this pathway is desirable but currently unavailable. We found that CXXC-type zinc finger protein 5 (CXXC5) serves as a negative feedback regulator of the Wnt/β-catenin pathway by ...

Interleukin (IL)-33, a newly identified member of IL-1 family of cytokines, plays a crucial role in polarizing Th2-associated immune responses. Recently growing evidence indicates that IL-33 also represents an important mediator of mucosal healing and epithelial restoration. In this study, we investigated the effect of IL-33 on antimicrobial infection and wound healing using a Staphylococcus au...

PURPOSE OF REVIEW This article describes why this review is timely and relevant. To report on the recent research, which advances our understanding and practice of palliative wound care (wound-related pain and symptom management or wound palliation). RECENT FINDINGS This article describes the main themes in the literature covered by the article. The main themes include the problem of malodour...
