Thanks to CCTV, countless parents are concerned about this problem, while in fact, stem cell therapy is not yet allowed in the United States. The disease: autistic hyperactivity 9 years old, autistic hyperactivity, low IQ performance, the age of 2.5 years at the onset of the disease, the performance of language regression, learned things again will not be the movement, behavior has improved. I would like to know if the stem cell treatment, according to the hospital, is considered to be a brain lesion, and the treatment behavior has improved by 60%. 1. for my child, does it play a role in the improvement of personality 2. can this improvement be maintained, and is it valid for one year? 3. Is the pathology genetic or other causes, which one is more likely. Feng Zhe: I would like to say that I am not a researcher in stem cell transplantation, but since I started to answer, I will give you some answers just for reference. The cause of childhood autism is still undetermined, and most scholars agree that it probably stems from a biological defect, but unfortunately exactly what that defect is remains unresolved. Using stem cell transplantation to treat autism is one idea, and I briefly searched some specialized literature. First, I did not see any research article on stem cell transplantation for autism in the professional literature search in Chinese. Secondly, in the English literature results, as a review article Stem Cell Therapy for Autism published in Journal of Translational Medicine in 2007 stated, there is no report on this in traditional journals. Thus, it can be seen that stem cell therapy for autism is still limited to those who work with stem cells, and is at a preliminary stage and still a long way from the clinic. It may be a new hope, but in the absence of research support, one needs to think twice about choosing whether to pursue such treatment. Many parents in China have recently paid attention to this issue, probably from the coverage of TV programs, but in fact it has not been long since this treatment was adopted in China, is China at the forefront in this field? I don’t think so, at least in terms of theory and detailed research, but China has been very bold in this “pushing unproven treatments into the clinic”. There are many lessons to be learned from the past. Hospitals adopting this treatment should be fully and honestly informed of new and detailed research on this treatment so that parents can make a choice. OK. stem cell therapy for autism is still a big gap in the clinical landscape and parents need to make a choice: do they fill it?
