Ethical and Bioethical Aspects in the Use of Stem Cells in Chronic Spinal Cord Injuries

Abstract

One of the fundamental dogmas maintained in neuroscience until the last century held that regeneration of the nervous system cannot occur in stages of adult life. However, it has been shown in several species during the postnatal stage and throughout life, that new neurons continue to be generated in some places in the human body. Objectives: The research was: to evaluate ethical and bioethical aspects in patients who were treated with an autologous stem cell implant in chronic spinal cord injuries. Method. An analysis is made of the ethical aspects that accompany the implantation of autologous stem cells in chronic spinal cord injuries. The results are evaluated at the "Enrique Cabrera" Surgical Clinical Teaching Hospital. Results: Ethical dilemmas are expressed and that have, among their relevant principles, the inviolability of human life. In higher animals, stem cells according to their evolutionary state can be embryonic and somatic or adult. Currently there is an extraordinary controversy about which stem cells to use from embryonic or adult ones, a debate in which both scientific, ethical, religious, social and political aspects have been included. One aspect of the scientific debate is related to the generative capacity of tumors by embryonic cells. From the ethical point of view, it has been argued that the use of human embryonic stem cells implies the destruction of embryos and it has been considered that life begins at the same moment of the union of the sperm with the ovum and that this would be equivalent to the destruction of a human life which would not be justifiable. Others do not agree with these criteria and argue that their use to save lives through research or therapy would be justified. Conclusions The physical disability produced by a chronic spinal cord injury raises an ethical dilemma about the use of stem cells, anticipating that the main controversy about this action has to do fundamentally with the way in which they are obtained.
