Advantages of therapeutic cloning
Therapeutic cloning has many advantages. It is used to create skin grafts for burn victims and is used in the treatment of spinal cord injuries.
Organs for transplant patients can also be created in this manner. In addition, because the cells come from the patient herself, there is no risk of stem cell rejection.
Therapeutic cloning can be used to treat a variety of diseases, including Alzheimer's disease, Parkinson's disease and cardiovascular disease.
Ethics is at the core of the debate regarding cloning. In particular, many individuals are against the use of embryonic stem cells (embryonic cloning) in cloning research and cloning procedures.
Reproductive cloning is particularly contentious, as some individuals fear that human cloning will take place or that babies will be cloned to have specific genetic characteristics.
In addition, therapeutic cloning also brings with it many ethical concerns and is prohibited in many countries. This is because therapeutic cloning uses human embryonic cells, which are destroyed following the removal of their stem cells.
Cord Blood Stem Cells and Cloning
Cord blood stem cell research is ongoing and its uses in cloning are under extensive evaluation and testing. Many individuals believe that umbilical cord blood stem cells present a more ethically responsible way to conduct therapeutic cloning, thereby helping alleviate much of the controversy surrounding stem cell research.
Also, collecting stem cells from umbilical cord blood is a less complicated process compared with obtaining stem cells from other sources.
Currently, storing umbilical cord blood in a cord blood bank allows for the treatment of disease or illness in children. In the future, stem cell cloning research may permit the use of stem cells to treat not only the child whose cord blood is stored, but also his relatives, providing more comprehensive therapeutic options.
