[09:57.34]13 But suppose, instead, that scientists could take one of your cells—any cell—and merge it with a human egg.
[10:06.51]The egg would start to divide, to develop, but it would not be permitted to divide more than a few times.
[10:15.13]Instead, technicians would bathe it in proteins that direct primitive cells, embryo cells, to become marrow cells.
[10:26.05]What started out to be a clone of you could grow into a batch of your marrow—the perfect match.
[10:34.38]14 More difficult, but not inconceivable, would be to grow solid organs, like kidneys or livers, in the same way.
[10:44.31]15Another possibility is to create animals whose organs are perfect genetic matches for humans.If you need a liver,
[10:53.92]a kidney, or even a heart, you might be able to get one from a specially designed pig clone.
[11:01.68]16 The possibilities are limitless, scientists say, and so, some argue,
[11:07.74]we should stop focusing on our hypothetical fears and think about the benefits that cloning could bring.
