Beyond these, the company is progressing with Engineered Skin Substitute (ESS), a cell therapy-based product for autologous skin replacement, currently in mid-stage clinical development for severe, life-threatening burns. The company has established a collaborative research and development agreement with both the U.S. Army Institute of Surgical Research and Rutgers University.
