The major way in which therapeutic cloning and reproductive cloning differ is that reproductive cloning cannot in reality be accomplished, while therapeutic cloning can.

therapeutic cloning seeks to provide cells and tissues for use in treatment of human diseases.

reproductive cloning can only be done in plants, therapeutic cloning only in animals.

reproductive cloning uses adult stem cells, therapeutic cloning uses embryonic stem cells.

There is no difference: both processes seek to obtain a genetically pure individual.
