According to the public relations and information center of the Vice-Presidency for science and technology affairs, Amir Ali Hamidieh, secretary of stem cells science and technology development headquarter, stated in this congress: by referring to website of clinical trials, it is determined that more than 300 clinical trials have been registered in the world in the field of stem cells and pain so far.

While the use of stem cells, which was only applied for treatment of cancer, dates back to 1957, application of stem cells has significantly extended today. Generally, stem cells are used in malignant and non-malignant blood diseases, treatment of burns, wound and acne, bone defects, restoration of articular cartilage and corneal transplants. Hamidieh explained: in treatment of chronic bone pain, osteoarthritis of tendons and ligament and even neural pains, several studies have been performed using stem cells, which have yielded promising results. Currently, pain is one of the medical problems of human societies, in a way that about one and a half billion individuals in the world are dealing with chronic pain of arthritis and neuropathy. Given the fact that the destruction of a part of tissues and cells is responsible for these chronic pains, replacement of the damaged areas not only leads to the restoration of that region, but also it eliminates pain.

He continued: multifocal, double-blind and randomized studies with the cooperation of more than 300 patients in a number of clinical trials on discogenic pains with the use of mesenchymal stem cells have indicated significant improvement in pain and restore of lumbar damages in these patients. We hope that such clinical trials be registered in Iran and research be initiated in this area, so that we could observe considerable advancement in application of stem cells in Iran along with the other advanced countries.
