In these studies regarding stem cell transplants in different diseases, identifying the location of implanted cells and distinguishing them from endogenous cells is the first and most important step.

Until now cell replenishment (transplant therapy) has been viewed as unlikely to succeed due to allograft rejection in this sensitized immune environment. However, advances in stem cell biology give new hope for deriving patient-specific, autologous oligodendrocytes which may tip the balance to favor repair.

When we consider the morality of each proposal in turn, we find as to several that what defends them also defends the use of surplus embryos and clones in general. That leaves no reason to abandon the general case for the special case of compromised life forms. Another of the proposals is morally indefensible. Still other proposed techniques would themselves use or risk using embryos, not to mention that they may fail to produce pluripotent cells of sufficient quality.

While there are currently no federally legislated constraints on the use of private funds for this research, there is a consensus opinion in the scientific community that without NIH support for newly created embryonic stem cell lines, progress in this important realm of research will be severely constrained. A May, 2005, report by the President's Council on Bioethics, \"Alternative Sources of Pluripotent Stem Cells,\" outlines several proposals for obtaining pluripotent stem cells without the destruction of human embryos. One of these methods, Altered Nuclear Transfer, proposes to use the technology of somatic cell nuclear transfer (SCNT), but with a preemptive genetic or epigenetic alteration that precludes the integrated and coordinated organization essential for natural embryogenesis. Drawing on insights from systems biology, the distinction between totipotency (capacity to form a whole organism) and pluripotency (capacity to form all the cell types) is explored. The implications of this distinction are used to discuss the moral arguments for the inviolability of nascent human life and the moral standing of entities with only partial and unorganized developmental potential. Away forward is proposed that may open positive avenues of advance in both stem cell research and a broader arena of research in developmental biology.</p>","PeriodicalId":520781,"journal":{"name":"Stem cell reviews","volume":" ","pages":"293-300"},"PeriodicalIF":4.8,"publicationDate":"2005-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1385/SCR:1:4:293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26476333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
