Live mice created from stem cells, and could also work for humans
Scientists have created live mice from stem cells and believe the same could be done for humans.
24 Jul 2009
Chinese researchers used cells, known as induced pluripotent skin cells (iPS), that have been reprogrammed to look and act like embryonic stem cells. Embryonic stem cells, taken from days-old embryos, have the power to morph into any cell type and, in mice, can be implanted into a mother's womb to create living mouse pups.
Their experiment, published in Nature, means that it is theoretically possible to clone someone using ordinary connective tissue cells found on the person's skin, but the experts were quick to distance themselves from such controversy. the rest
Researchers produce cells they say are identical to embryonic stem cells
Scientists in China use cells from adult mice to breed new mice. The breakthrough results are hailed as an advance toward eliminating the need for fetal stem cells in a variety of applications.

If stem cells could be created from normal human cells that would really help us to overcome some of the ethical barriers related to stem cell research. However, when it comes to cloning complete organisms using stem cells, the ethics are still a bit shady, regardless of where the stem cells are harvested from.
If you are planning on completing medical science fair projects then you need to read the special rules for ethical treatment of your test subjects before beginning your experimentation.
