But most considered that embryos stem cells would still allow treatments for a wider range of diseases than adult cells. There is more radical idea, to adapt Roslin's work to reprogramme ordinary adult non-stem cells directly into the desired type of cell, without intermediate embryos. This is highly speculative, but several methods have been suggested which merit serious research investment. But it would probably mean limited embryo research as a bridge in understanding. For that one purpose personally I might countenance it, on condition that it avoids using embryos routinely.
Cloning only comes in play if there was a problem of rejection.
By definition these cells would be of a different genetic type from the patient. For some diseases cloning might be used to make replacement cells of the same genetic type as the patient, to minimise rejection. A skin or blood sample would be taken from the patient. The Dolly technique would be used to create a temporary cloned embryo, but instead of implanting it to make a cloned baby, it would be used to create genetically matched cells. No one knows yet if it would work, or how often such a route might be preferred over using IVF embryos.
