wound-healing

Considering the enormous scale of the global wound dressing market, optimized wound dressings have tremendous market prospects. Chitosan (CS) shows excellent antibacterial and hemostatic activity, and hyaluronic acid (HA) has good biocompatibility, hygroscopicity, and anti-inflammatory activity. For these reasons, both are widely used as wound dressings. In this review, we systematically discuss …

Chronic non-healing wounds, including diabetic ulcers, venous leg ulcers, and pressure ulcers, represent a significant clinical burden worldwide, associated with major economic costs and impaired quality of life. Although stem cell–based therapies have shown regenerative potential, recent accumulating evidence indicates that their therapeutic effects are primarily mediated by paracrine signaling …

Nature Biomedical Engineering, Published online: 27 May 2026; doi:10.1038/s41551-026-01687-7 Engineered cells embedded in a removable wound patch provide sustained local cytokine delivery, reshaping immune and tissue repair programs to speed healing in rodent and porcine excisional wound models.

Introduction: Metabolic disorders, particularly diabetes mellitus, can lead to the formation of chronic wounds, slowing healing processes. A key factor impeding wound healing is the decreased production of endogenous nitric oxide (NO) due to a hyperglycemic microenvironment. Nitric oxide (NO) is a key signaling molecule produced by three different isoforms of nitric oxide synthase (NOS) – iNOS, e…

A new living bandage accelerates healing across multiple wound types, researchers report.

Impaired mitophagy and the accumulation of damaged mitochondria are key drivers of endothelial cell (EC)dysfunction in diabetic wounds.

When people think about healing from a wound, they usually think about medical care, bandages, and good nutrition. But scientists are now learning that the mind and emotions can also play a powerful role in how the body recovers. A recent study by researchers at the Medical University of South Carolina and collaborating institutions has […] The post Loneliness can delay wound healing at genetic l…

This study successfully constructed shikonin-Co nanoparticles (Co-Shik NPs) and systematically evaluated their healing effects on diabetic wounds. The nanoparticles, prepared via a self-assembly method, exhibited uniform particle size and stable structure. In vitro experiments demonstrated that the material showed no cytotoxicity at a concentration of 16 mg/L, significantly scavenged reactive oxy…

Chronic wounds are a serious health problem that affect millions of people around the world. In developed countries, about 2% of the population suffers from wounds that do not heal properly. These wounds can last for months or even years, causing pain, infection, and high medical costs. Current treatments can be expensive and sometimes come […] The post Seaweed could heal wounds naturally, study …

Treating wounds may soon become safer and more precise thanks to a new invention from scientists at Brown University. In a recent study published in the journal Science Advances, researchers developed a special wound dressing that can release antibiotics only when harmful bacteria are present. This new approach could help wounds heal faster while also […] The post Smart bandage releases antibioti…

When nutrients run low, hair follicle stem cells can stop making hair and help repair the skin instead. A drop in the amino acid serine triggers this switch, accelerating wound healing. Human skin relies on two main groups of adult stem cells: epidermal stem cells and hair follicle stem cells. Under normal conditions, each group [...]

Researchers found that a common antibiotic-resistant bacterium prevents wounds from healing by chemically paralyzing skin cells rather than attacking them directly. Scientists from an international research group led by Nanyang Technological University, Singapore (NTU Singapore), have identified an approach that may help chronic wounds heal faster, including wounds infected with antibiotic-resist…

Diabetic wounds, particularly foot ulcers, are among the most serious complications faced by patients with diabetes. These chronic wounds often fail to heal properly due to a combination of poor blood flow, persistent inflammation, and infection. The consequences can be severe, ranging from loss of mobility to amputations, and they place a substantial burden on healthcare systems worldwide. Again…

Microneedles allow scientists to precisely control the delivery of drugs to chronic wound sites and restore natural healing processes. The post Silk microneedles could restore wound healing in diabetic patients appeared first on Advanced Science News .

Speeding up diabetic wound healing Releasing the 'healing brake' on our immune system Chronic skin wounds affect many diabetic patients, with a negative impact on their quality of life. Sophia Maschalidi (VIB-UGent) discovered how to accelerate wound healing and decrease the risk of infection. Key facts (estimates for 2021 from the International Diabetes Federation) - Globally, an estimated 537 m…

It’s not pretty, and its name is a turnoff. But a venous leg ulcer (VLU) should be taken seriously, because of the consequences if it doesn’t heal. Improved treatment of [...] The post Toward Better Wound Healing appeared first on NEOMED .

New insights on circumventing a key obstacle on the road to anti-scarring treatment have been published by Maksim Plikus, an […]

Severe skin injuries affect millions of patients each year worldwide. These lead to serious issues, such as the formation of nonfunctional large scar tissue and the loss of skin appendages (such as hair follicles and sebaceous glands; etc). This can cause the patients insufferable bodily discomfort and a poor quality of life. Current available treatments […]
