Our Vision
To build a future where the body’s natural healing abilities
are supercharged to improve the quality and length of life.
To battle and treat multiple inflammatory diseases and ailments through the use of stemXcell activated stem cell therapies.

stemXcell™︎ is the platform through which we discover, test and develop activated mesenchymal stem cells that are pre-programmed to treat targeted inflammatory diseases.
Today, we are preparing for FDA-authorized clinical trials that will test our stemXcell™︎ MSC treatments with enhanced immunomodulatory properties for treating chronic and acute liver diseases. Additionally, we are pursuing preclinical and clinical studies for other disease models, including NASH and ASH, and are continuing our research into numerous other inflammatory diseases.
