One way would be to take them from an adult source however these cells may not be as abundant as cells taken from embryos. There is also a possibility that the cells could be harvested from the umbilical cords, which are donated by women who have just delivered a baby. Of course, there are other instances of stem cells being taken from aborted babies. The argument here is that the mothers do not want to keep the child as so why not donate them to stem cell research in order that they may help save somebody else. There are also embryos, which are left at fertility clinics, which are going to be destroyed and again, why not donate them to stem cell
