If gene isolate from marrow cells producing ADA is introduced into cells at early embryonic stage, it could be a permanant cure of ADA deficiency because the early embryonic cells :

1. Are more differentiated than the later stage cells

2. Are constantly dividing and do not get differentiated 

3. Are easy to manipulate than the later stage cells

4. Are virtually immortal
