Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.

You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases.
