Electrical stimulation promotes the wound-healing properties of diabetic human skin fibroblasts
This study evaluated the effect of low (20 and 40 mV/mm) intensities of electrical stimulation on the proliferation and migration of skin fibroblasts from diabetic donors. We also examined the effect of electrical stimulation on modulating the capacity of fibroblasts to contract collagen gel, express alpha-smooth muscle actin, and secrete proteolytic enzymes involved in regulating extracellular matrix synthesis and degradation. Our study shows that 20 and 40 mV/mm of stimulation increased the growth of fibroblasts extracted from diabetic patients but not from non-diabetic donors. Electrical stimulation increased the migration of diabetic fibroblasts, their capacity to contract collagen gel, and the expression of alpha-smooth muscle actin and promoted different proteolytic enzymes involved in accelerating wound healing. Overall results confirm the effectiveness of electrical stimulation in modulating the wound healing activities of fibroblasts extracted from diabetic skin donors. This study, therefore, suggests the possible use of electrical stimulation to promote diabetic foot ulcer healing by stimulating the wound healing properties of skin fibroblasts.
期刊介绍：
Journal of Tissue Engineering and Regenerative Medicine publishes rapidly and rigorously peer-reviewed research papers, reviews, clinical case reports, perspectives, and short communications on topics relevant to the development of therapeutic approaches which combine stem or progenitor cells, biomaterials and scaffolds, growth factors and other bioactive agents, and their respective constructs. All papers should deal with research that has a direct or potential impact on the development of novel clinical approaches for the regeneration or repair of tissues and organs.
The journal is multidisciplinary, covering the combination of the principles of life sciences and engineering in efforts to advance medicine and clinical strategies. The journal focuses on the use of cells, materials, and biochemical/mechanical factors in the development of biological functional substitutes that restore, maintain, or improve tissue or organ function. The journal publishes research on any tissue or organ and covers all key aspects of the field, including the development of new biomaterials and processing of scaffolds; the use of different types of cells (mainly stem and progenitor cells) and their culture in specific bioreactors; studies in relevant animal models; and clinical trials in human patients performed under strict regulatory and ethical frameworks. Manuscripts describing the use of advanced methods for the characterization of engineered tissues are also of special interest to the journal readership.
