Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel that promoted complete wound closure within 72 hours in laboratory tests. The material combines silk proteins with a plant-derived compound, creating a water-based gel that can be injected minimally invasively.
The hydrogel represents a potential new approach to soft tissue repair, addressing a key challenge in regenerative medicine: achieving rapid, effective closure without invasive surgery. Silk proteins are known for their biocompatibility, while the plant compound contributes structural integrity.
In the laboratory setting, the hydrogel was tested on wound models and demonstrated the ability to close tissue defects entirely within three days. The researchers did not specify the exact mechanism or the type of wounds used, and further studies are needed to confirm efficacy in living organisms.
If validated in animal and human trials, the technology could shift wound care toward less invasive interventions. However, the current results are limited to laboratory conditions, and scalability, safety, and long-term outcomes remain unknown.
“The plant-derived additive provides enhanced mechanical properties,” noted the study authors, though they cautioned that clinical translation will require extensive testing.
