Technically, yes, but we generally advise against it.
Firstly, donor cells take about a month to be cultivated, which would mean you’d have to come to the clinic twice: first for harvesting the cells, and then for an actual treatment for the child. Secondly, the ASD can sometimes be genetic, which means that the parent’s stem cells might not be as effective in treating autism in the child as the donor cells with no ASD history in the family. And last, compared to donor stem cells from the placenta or umbilical cord, adult donor’s cells are typically fewer in number and less active.
For these reasons, we generally recommend using cells from a donor who is not a patient’s parent, with all the necessary safety checks and precautions. However, you can always discuss this issue with your consulting doctor and reach a final decision together.
