Method for producing sulfur compounds in cells shows promise for tissue repair

Scientists from Penn State and Osaka Metropolitan University in Japan have developed a new method to generate sulfur compounds, called polysulfides, inside cells. The method induces a chemical reaction that converts hydrogen sulfide to polysulfides inside cells by using self-assembled nano-sized core-shell structures. These structures can be taken up by cells and protect what's inside – in this case, a metal complex that can convert hydrogen sulfide to polysulfides. Delivering polysulfides as a treatment could have implications for treating wounds and repairing tissues, the scientists said.
