This study investigated the safety and efficacy of fetal stem cell (FSC) transplantations in treating children diagnosed with ASDs. Subjects were monitored at pre, and then 6 and 12 months following the transplantations, which consisted of two doses of intravenously and subcutaneously administered FSCs. The Autism Treatment Evaluation Checklist (ATEC) test and Aberrant Behavior Checklist (ABC) scores were performed. Laboratory examinations and clinical assessment of adverse effects were performed in order to evaluate treatment safety. No adverse events of significance were observed in ASD children treated with FSCs, including no transmitted infections or immunological complications. Statistically significant differences (p<0.05) were shown on ATEC/ABC scores for the domains of speech, sociability, sensory, and overall health, as well as reductions in the total scores when compared to pretreatment values. We recognize that the use of FSCs remains controversial for the present. The results of this study, however, warrant additional investigations into the mechanisms of cell therapies for ASDs, while prompting the exploration of FSCs as “biopharmacies” capable of manufacturing the full array of cell-signaling chemistry.
