About 1.3 million people in the United States have type 1 diabetes, which requires constant monitoring and regular injections of insulin. The autoimmune disease attacks the insulin producing beta cells in the pancreas and replacement of those cells has long been viewed as an ideal approach to treating the disease. The problem, though, has been finding a reliable supply or replacement cells and protecting them from the body’s immune system while allowing them to recieve needed nutrients, as well as deliver insulin to the body. San Diego-based ViaCyte is now in human clinical trials with a promising approach to treating the disease. We spoke to Paul Laikind, president and CEO of ViaCyte, about the company’s cell therapy, its critical financial support from the California Institute for Regenerative Medicine and JDRF, and why its investigational product may represent a functional cure.
