I need a well written COMPREHENSIVE essay that answers in concise scientific language. Appropriate & reputable sources should be used. ALL assignments should be written in YOUR ORIGINAL WORDS and no more than 5% of your paper should be quotes. A paper that is not original and authored by you will result in me rejecting your answer.

Utilizing information in "The second coming of gene therapy," "The super cell," "Gene therapy could expand stem cell’ promise" and at least three appropriate additional sources (other than your text) , answer the following prompts:

What is stem cell therapy and what is gene therapy?
What problems have scientist encountered in the past while trying to use these technologies separately to treat diseases?
