I appreciate your quest for knowledge but the fact is that stem cell therapy
is still in experimental stages and no concrete treatment has been put forward by it's use except in bone marrow transplant
Medical researchers believe that in future we shall be able to treat patients by stem cell therapy in people suffering from diabetes type 1, Parkinsonism,cancers etc.
Moreover diabetes type 2 is a lifestyle disease
as compared to diabetes type 1 which is an auto immune disorder.
You should focus on keeping your blood sugar levels by appropriate medications,regular exercises snd taking precautions regarding your diet.
Make sure that you keep your sugar levels in tight control as uncontrolled diabetes
results in various types of future micro as well as Macrovascular complications.
