Abstract
Human amniotic membranes (hAMs) are widely used as wound management biomaterials, especially as grafts for corneal reconstruction due to the structure of the extracellular matrix and excellent biological properties. However, their fragile nature and rapid degradation rate hinder widespread clinical use. In this work, we engineered a novel self-powered electronic dress (E-dress), combining the beneficial properties of an amniotic membrane and a flexible electrical electrode to enhance wound healing. The E-dress displayed a sustained discharge capacity, leading to increased epidermal growth factor (EGF) release from amniotic mesenchymal interstitial stem cells. Live/dead staining, CCK-8, and scratch-wound-closure assays were performed in vitro. Compared with amniotic membrane treatment alone, the E-dress promoted cell proliferation and migration of mouse fibroblast cells and lower cytotoxicity. In a mouse full-skin defect model, the E-dress achieved significantly accelerated wound closure. Histological analysis revealed that E-dress treatment promoted epithelialization and neovascularization in mouse skin. The E-dress exhibited a desirable flexibility that aligned with tissue organization and displayed maximum bioactivity within a short period to overcome rapid degradation, implying great potential for clinical applications.

Abstract
Electrical stimulation as a mode of external enhancement factor in wound healing has been explored widely. It has proven to have multidimensional effects in wound healing including antibacterial, galvanotaxis, growth factor secretion, proliferation, transdifferentiation, angiogenesis, etc. Despite such vast exploration, this modality has not yet been established as an accepted method for treatment. This article reviews and analyzes the approaches of using electrical stimulation to modulate wound healing and discusses the incoherence in approaches towards reporting the effect of stimulation on the healing process. The analysis starts by discussing various processes adapted in in vitro, in vivo, and clinical practices. Later it is focused on in vitro approaches directed to various stages of wound healing. Based on the analysis, a protocol is put forward for reporting in vitro works in such a way that the outcomes of the experiment are replicable and scalable in other setups. This work proposes a ground of unification for all the in vitro approaches in a more sensible manner, which can be further explored for translating in vitro approaches to complex tissue stimulation to establish electrical stimulation as a controlled clinical method for modulating wound healing.

Abstract
Dermal wounds and their healing are a collection of complex, multistep processes which are poorly recapitulated by existing 2D in vitro platforms. Biomaterial scaffolds that support the 3D growth of cell cultures can better resemble the native dermal environment, while bioelectronics has been used as a tool to modulate cell proliferation, differentiation, and migration. A porous conductive hydrogel scaffold which mimics the properties of dermis, while promoting the viability and growth of fibroblasts is described. As these scaffolds are also electrically conductive, the application of exogenous electrical stimulation directs the migration of cells across and/or through the material. The mechanical properties of the scaffold, as well as the amplitude and/or duration of the electrical pulses, are independently tunable and further influence the resulting fibroblast networks. This biomaterial platform may enable better recapitulation of wound healing and can be utilized to develop and screen therapeutic interventions.

Abstract
Electrical stimulation (ES) has been frequently used in different biomedical applications both in vitro and in vivo. Numerous studies have demonstrated positive effects of ES on cellular functions, including metabolism, proliferation, and differentiation. The application of ES to cartilage tissue for increasing extracellular matrix formation is of interest, as cartilage is not able to restore its lesions owing to its avascular nature and lack of cells. Various ES approaches have been used to stimulate chondrogenic differentiation in chondrocytes and stem cells; however, there is a huge gap in systematizing ES protocols used for chondrogenic differentiation of cells. This review focuses on the application of ES for chondrocyte and mesenchymal stem cell chondrogenesis for cartilage tissue regeneration. The effects of different types of ES on cellular functions and chondrogenic differentiation are reviewed, systematically providing ES protocols and their advantageous effects. Moreover, cartilage 3D modeling using cells in scaffolds/hydrogels under ES are observed, and recommendations on reporting about the use of ES in different studies are provided to ensure adequate consolidation of knowledge in the area of ES. This review brings novel insights into the further application of ES in in vitro studies, which are promising for further cartilage repair techniques.

Arch Oral Biol 2022; 141:105498.

Abstract
OBJECTIVES This study aims to investigate the effects of cannabis smoke condensate (CSC) on the adhesion, growth, and signaling pathways of human gingival epithelial cells. DESIGN The effects of CSC on cell shape and adhesion, and viability were evaluated after 30 min, 60 min, 2 h, and 24 h of exposure using microscopic observation, cell metabolic activity, and lactate dehydrogenase activity assays. The effects of CSC on cell apoptosis, necrosis, autophagy, and oxidative stress were determined through flow cytometry, while apoptotic and autophagic gene expression were identified via an RT2-PCR array. Phosphorylated signaling pathway proteins were measured using flow cytometry. RESULTS CSC deregulated gingival epithelial cell shape and adhesion, decreased cell viability, and increased lactate dehydrogenase release. Its toxic effects included apoptosis, autophagy, and oxidative stress. Moreover, it modulated seven specific apoptotic and six autophagic genes. Furthermore, it decreased phosphorylation in signaling proteins, such as STAT5, ERK12, P38, and nuclear factor κB. CONCLUSIONS CSC has notable adverse effects on gingival epithelial cells. This finding indicates that cannabis smoke could impair gingival epithelial cell innate immune function, leading to gingivitis and periodontitis. Oral health professionals may need to document observed modifications in the oral cavity of patients who smoke cannabis and consider these potential changes during clinical care.

J Tissue Eng Regen Med 2022; 16:643-652.

Abstract
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.
