Wearable bioreactor was attached to the wound site to deliver the progesterone locally for 24 hours.
24 hour of exposure led to 9 months of changes in gene expression, innervation, and patterned growth.
Device contains a silk protein-based hydrogel which is applied directly to the wound.
Drug-device combination could be a new model for the regeneration of non-regenerative species.
Results have published in Cell Reports.
