Asymmetrex, LLC is a Massachusetts (U.S.) life science tools company that specializes in the development of technologies for the evaluation of drug candidate effects on adult tissue stem cells. The company’s AlphaSTEM Test™ technology is the first and only method that provides specific and accurate counting of adult tissue stem cells, which are essential for normal tissue and organ renewal and function. Drugs that are toxic to adult tissue stem cells cause chronic organ failure, a major cause of drug safety failure late in expensive clinical trials. Asymmetrex’s AlphaSTEM Test™ can predict such wasteful drug candidates much earlier in inexpensive human cell cultures. The AlphaSTEM Test™ can also discover drugs that augment the beneficial attributes of tissue stem cells for applications in wound repair and other regenerative medicine therapies.
