In order for the diabetic's body not to reject the new islet cells from a donor, the doctors would have to inject immunosuppressant drugs such as Rapamume. This drug will eventually be the new lifeblood of the Type-1 patient, since the moment he stops taking in immunosuppressants, his body will react on the foreign islets that have been injected on him. This would result in more complication instead of an increased survival rate.
