Reserchers Report Promising Results Using Silver-Releasing Scaffolds in MRSA Infection of Bone

Article

Researchers developed a biocompatible scaffold capable of controlled-release of silver ions and have shown in a new study that it can inhibit infection of bone by methicillin-resistant Staphylococcus aureus, known as MRSA. The antimicrobial properties of silver combined with a biodegradable scaffold that can be seeded with bone-forming stem cells offers a potential implant system for treating and preventing bone infection, as described in an article published in Tissue Engineering, Part A, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Mahsa Mohiti-Asli, PhD, and coauthors from University of North Carolina at Chapel Hill, North Carolina State University (Raleigh), Silpakorn University (Nakornpathom, Thailand), and University of Missouri (Columbia), present an experiment in which they seeded bone-forming stem cells on three-dimensional scaffolds either with or without MRSA. The researchers assessed bacterial biofilm formation to determine the effect of silver ions on bone infection (osteomyelitis). They report their findings in the article titled "Evaluation of Silver Ion-Releasing Scaffolds in a 3D Coculture System of MRSA and Human Adipose-Derived Stem Cells for Their Potential Use in Treatment or Prevention of Osteomyelitis."

"Hybrid therapeutic approaches such as this combination of a regenerative and anti-infective platform are transforming our attack on complex musculoskeletal diseases," says co-editor-in-chief Peter C. Johnson, MD, principal of MedSurgPI, LLC and president and CEO, Scintellix, LLC, Raleigh, NC.
