ACT's Cloning Advances Make Embryonic Stem Cell Therapies More Plasuible

Occasionally critics of stem cell research suggest that, for embryonic stem cells to actually be used for therapeutic purposes, millions of human eggs would have to be harvested from women. But, based on advances in stem cell cloning and the idea of histological tissue matching, ACT's Dr. Robert Lanza here suggests something quite different: "It would take just 40 batches, or lines, of parthenote-generated stem cells to create tissue matches for 70 percent of the U.S. public... Embryonic stem cells are immortal, so it would not take many human eggs to create several dozen lines. "
