Scientific American recently reported that there may be a new type of stem cell called parthenogenetic stem cells (http://www.scientificamerican.com/article.cfm?id=you-say-embryo-i-say-parthenote). Parthenogenetic stem cells are similar to embryonic stem cells but come from an unfertilized egg. This stem cell is created by tacking a unfertilized egg and adding certain hormones to it. The hormones creates the effect of a fertilized egg but since there is no genetic dna transferred the egg cannot become a fetus. However while these cells will become any kind of cell it is still tricky to control. Also research for this type of cell is hard to come by. The U.S. government is currently defining parthenotes as embryos so the government is not allowed to fund any of the research. Many research facilities rely on federal funding so only very few private researching firms can work on it.
This is just another are in genetics that needs researchers and funding. This could be a remarkable step forward. Now parent that are unable to have children could donate eggs and help save someone's life. Also all the "old" eggs in facilities could be used for research or to help save a life instead of wasting away or being thrown away. Also by using these type of cells we might be able to mix adult cells and parhenogenetic stem cells to create healthier and longer lasting muscles,tissues,organs, etc...
Stem cell therapy is the most popular and effective treatment for chronic disease like diabetes, copd, retinitis pigmentosa, alzheimer's.
