Encapsulation of living cells enables them to (i) be implanted as therapeutics (ii) survive and be controlled as all other living cell in the body (iii) be applied directly at ‘point of need’ in the body & (iv) overcome the body’s immune system to deliver therapeutics. The technology has a wide application to many therapeutic areas including oncology, metabolic disease, cardio-vascular, inherited disease, infectious disease, degenerative disease, immunology and biotechnology. The encapsulation technology is unique and has been shown to be safe and efficacious in humans.
