There is a picture of stem cell therapy: It is in harmony with the body’s own way of functioning. Damaged tissue is regenerated as the body always regenerates tissue: through stem cells maturing into new body cells.
Patients can then hope for a body without a trace of disease: a healed body that takes care of itself as a healthy body does. It is almost as if we were not dealing a treatment at all, for the body restores itself, as it always does.
Stem cell therapy is certainly an important step towards effective treatment of several currently incurable diseases. The methods can also be said to be based on the body’s own way to regenerate tissue.
Nevertheless, I think we should emphasize that stem cell therapies are treatments next to others, with risks and benefits. Cells are transplanted into patients whose immune system can react. The implants may need to be checked regularly, or even be replaced. The transplantation can go wrong. And so on.
Stem cell therapy does not “transcend” all disease treatment hitherto by supporting the body’s own way of healing itself. We are still dealing with treatments of patients, rather than with “salvation from disease.”
Rhetoric of salvation is dangerous. It invites magicians and our faith in them. It justifies sacrifices to the benefit of Mankind. It disturbs our judgement.
