Summary

This study tested whether a child's own bone marrow stem cells, combined with educational therapy, can safely reduce autism symptoms. 54 children aged 3-7 with moderate to severe autism took part. Researchers measured changes in behavior, social skills, and quality of life. The goal was to see if this approach helps control the condition, not cure it.
