I hate to break it to you, but the successful iPSC work was based on embryonic stem cell research. >>>
Um, I hate to break it to you, but ipsc work does NOT involve using embryos. In order to create and obtain these cells, the scientists, not the RCC or any other church, used retroviruses and gene therapy.
Sorry, but even if there aren't embryonic cells used now, they were used in early stages of the research. Shinya Yamanaka studied embryonic stem cells to identify the most active genes in them, to know what to try inserting into non-pluripotent cells with retroviruses.
Without the look at embryonic stem cells, the Kyoto team wouldn't have known what to do to get the embryonic stem cell action.
