What is GenAssist?
GenAssist develops biomaterials to regenerate muscle after devastating traumatic injuries. Their lead innovation, MyoSponge, is a patented scaffold made of proteins that support muscle cells and guide the body to regrow functional tissue instead of scar. In preclinical studies across multiple animal models, it has rebuilt muscle fibers, increased muscle mass, and restored strength.
Medicine has no therapy that can regenerate lost skeletal muscle. Once it is gone, the body cannot replace it. GenAssist is changing that reality by advancing its scaffold toward the clinic, offering patients the first real chance to regain strength, mobility, and independence after catastrophic injury.
