Regenerative medicine has been enthusiastically received, as it promises to make further interventions redundant. Also, it may provide solutions for as-yet-untreatable conditions, and it may benefit anyone from neonates (possibly even fetuses) to the elderly. All medical fields have embraced it, from dentistry and orthopedics to neurosurgery and cardiology. Its growth is based on our increased knowledge of cell—and especially stem cell—biology and biomaterials, and on the increasing prevalence of degenerative diseases. In the future, regenerative medicine may therefore touch most of our lives. While there has been a steady increase in the volume of medical research, the field has been largely ignored in bioethics.
