The use of embryonic stem cells for medical-therapeutical purposes: ethical issuesCitation
Læknablaðið 2003, 89(4):321-5Abstract
The capacity of self-renewal and differentiation renders stem cells an appealing option for cell replacement therapy. Although stem cells are known to exist in fully differentiated tissues, those derived from embryos have generated greater scientific interest due to their capacity for differentiation. The use of embryos as a source of stem cells raises, however, difficult ethical questions, since removing stem cells from an embryo terminates further development of the embryo. The ethics debate on the use of embryonic stem cells focuses on the biological and ethical status of the embryo and the sanctity of life. This paper reviews various ethical issues pertinent to the use of embryonic stem cells for medical purposes.Þar sem stofnfrumur geta fjölgað sér endalaust og sérhæfst í aðrar frumutegundir þykja þær sérlega athyglisverðar frá sjónarhóli læknavísindanna. Hefur athygli vísindamanna sérstaklega beinst að stofnfrumum fósturvísa þar sem sérhæfingargeta þeirra er öðrum stofnfrumum meiri. Við að nálgast þessar stofnfrumur stöðvast þroski fósturvísisins og því hafa slíkar framkvæmdir vakið upp margar áleitnar siðferðisspurningar. Umræðan um siðferðilegt réttmæti þess að nota stofnfrumur fósturvísa til lækninga snýst því í reynd um siðferðisstöðu fósturvísisins, upphaf lífsins og helgi þess. Í þessari yfirlitsgrein er varpað ljósi á þau sjónarmið sem hæst ber í umræðunni um réttmæti þess að nota stofnfrumur úr fósturvísum til lækninga.
