stem cell translation and bioethics

During the last three decades, considerable  hope and attention has led to the  initiation of the field of “regenerative  medicine”. This has resulted not from the  development of our ability to regenerate  any organ or tissue, with the exception  of the hematopoietic system-as widely  believed, but only from the prediction  that certain cells referred to as stem cells  show the capacity in vitro to apparently  undergo differentiation into cells of all  the three germal lineages when cultured  under various conditions. Such stem cells  have been found in embryos, in fetal tissue  and cord blood, in the placenta, in postnatal  bone marrow, fatty tissue, blood and practically everywhere else. doi: 10.5214/ans.0972.7531.12190201
