Healthy stem cells were extracted from an area at the junction of the cornea and white part of the eye called the limbus, cultured on fibrous tissue then placed in a single layer on the damaged eye. Dr. Graziella Pellegrini of the University of Modena’s Centre for Regenerative Medicine and her team of researchers found that sight was restored using stem cells implanted in eyes of patients damaged by chemical burns.Over 80 patients which amounted to more that 75% of patients treated, regained their sight after undergoing the stem cell procedure. These findings were anounced by Dr. Pellegrini at the International Society for Stem Cell Research meeting in San Francisco. Opaque eyes were transformed into functioning organs, appearing normal as the cultured adult stem cells grew and became healthy corneal tissue
