Because Model Organism's are non-human species, and researches don't want anything catastrophic to happen if they were using a human to experiment on.
The process you are referring to is somatic cell nuclear transfer (SCNT), also known as cloning. In SCNT, the nucleus of a somatic cell (cell without a nucleus) from one adult organism is transferred into an enucleated egg cell from another adult organism. This can be used for research purposes or to produce genetically identical organisms.
Well, there are controversial views with regards to stem cell research. Some would say that stem cell research is important as it has the potential to save many lives and greatly improve our medical knowledge. However, many would argue that it is 'playing God' and that we should not be using stem cells, as it is not natural - not how things were meant to be.
After the adult cycle, many organisms enter the senescent stage, which is characterized by the aging process and eventual decline in physical condition. This phase typically precedes death in the life cycle of organisms.
"The Cystic Fibrosis Foundation is not involved in funding research on the use of human embryonic stem cells. The CF Foundation has provided funds to an institution for research on human adult stem cells for CF research. This research grant is approximately $40,000 in total."American Journal of Respiratory and Critical Care Medicine Vol 173. pp. 1043-1045, (2006)http://ajrccm.atsjournals.org/cgi/content/full/173/9/1043
Present research indicates that adult stem cells are just as good as embryonic.
