There is a critical clinical need to develop therapies for non-healing diabetic foot ulcers. Topically applied mesenchymal stromal cells (MSCs) provide a novel treatment to augment diabetic wound healing. A central pathological factor in nonhealing diabetic ulcers is an impaired blood supply. It was hypothesized that topically applied allogeneic MSCs would improve wound healing by augmenting an...

Wounds naturally produce electric signals which serve as powerful cues that stimulate and guide cell migration during wound healing. In diabetic patients, impaired wound healing is one of the most challenging complications in diabetes management. A fundamental gap in knowledge is whether diabetic wounds have abnormal electric signaling. Here we used a vibrating probe to demonstrate that diabeti...

Care for diabetic wounds remains a significant clinical problem. The present study was aimed at investigating the effect of skin gelatin from Chum Salmon on defective wound repair in the skin of diabetic rats. Full-thickness excisional skin wounds were made in 48 rats, of which 32 were diabetes. The diabetic rats were orally treated daily for 14 days with skin gelatin from Chum Salmon (2 g/kg) ...

OBJECTIVE The effects of wound healing acceleration on diabetic rats were determined and compared using different laser wavelengths and incident doses. BACKGROUND DATA Many studies have demonstrated that low-level laser therapy (LLLT) can promote the wound healing on non-diabetic animals. METHODS Male Sprague-Dawley rats were used. Streptozotocin (70 mg/kg) was applied for diabetes inductio...

The diabetic wound healing is a common problem faced by both physicians and surgeons. The applications of nano biomaterials opened a new way to heal diabetic wounds. There were four parts in this review. First, we introduced the concept of the nano biomaterials. Second, we summarized systematically the mechanism of the nano biomaterials used for promoting wound healing. Thirdly, the application...

BACKGROUND Chronic inflammation is a characteristic feature of diabetic cutaneous wounds. We sought to delineate novel mechanisms involved in the impairment of resolution of inflammation in diabetic cutaneous wounds. At the wound-site, efficient dead cell clearance (efferocytosis) is a pre-requisite for the timely resolution of inflammation and successful healing. METHODOLOGY/PRINCIPAL FINDIN...

Dysfunction of macrophages (MΦs) in diabetic wounds impairs the healing. MΦs produce anti-inflammatory and pro-resolving neuroprotectin/protectin D1 (NPD1/PD1, 10R,17S-dihydroxy-docosa-4Z,7Z,11E,13E,15Z,19Z-hexaenoic acid); however, little is known about endogenous NPD1 biosynthesis by MΦs and the actions of NPD1 on diabetic MΦ functions in diabetic wound healing. We used an excisional skin wou...

Objective: To evaluate wound healing activity of ethanolic extract of Jasminum grandiflorum Linn. (J. grandiflorum) flowers in diabetic rats. Materials and Methods: Streptozotocin-induced diabetic Wistar albino rats were divided into six groups (n=6).Three groups – diabetic control, positive control (that received Glibenclamide) and treatment (that received J. grandiflorum Linn. Flower extract...
