This created 82 embryos, which were implanted into seven surrogate mothers. The process yielded only a single fetal clone, and that one died in utero. Researchers then turned to cumulus cells from the ovaries of a female named Rainbow, creating five cloned embryos. These were implanted in Allie, another surrogate, and this time an embryo took hold and grew. The result was cc, born Dec. 22 and announced with a flourish...
