Dolly was born July 5, 1996. This was a great time for science. The cloning of Dolly lead to many different research centers and health treatments facilities. Dolly died in 2002.


Ian Wilnut. Ian is an embryologist. He was the lead developer of Dolly. He implanted the gland into an embryo and implanted this embryo into a sheep. Another important scientist was Keith Cambell. Cambell was a stem cell scientist. He ordinated the key parts of the cell cycle.


This is one of the greatest scientific breakthroughs of the decade. This has lead to research in many different categories of cell therapy. Cell therapy treats many diseases like Leukemia and Parkinson's. This same treatment also treats cancer. Cancer is the largest killer in America. It takes around 560,000 lives a year.
