===Comparing SCNT to reprogramming===
Both the processes of SCNT and iPSCs have benefits and deficiencies. Historically, reprogramming methods were better studied than SCNT derived embryonic stem cells (ESCs).<ref name=TrounsonComment/> However, more recent studies have put more emphasis on developing new procedures for SCNT-ESCs. The major advantage of SCNT over iPSCs at this time is the speed with which cells can be produced. iPSCs derivation takes several months while SCNT would take a much shorter time, which could be important for medical applications. New studies are working to improve the process of iPSC in terms of both speed and efficiency with the discovery of new reprogramming factors in oocytes.{{citation needed|date=May 2014}} Another advantage SCNT could have over iPSCs is its potential to treat [[mitochondrial disease]], as it uses a donor oocyte.<ref name=TrounsonComment/> No other advantages are known at this time in using stem cells derived from one method over stem cells derived from the other.<ref name="pmid24180743">{{cite journal |vauthors= Langerova A, Fulka H, Fulka J | title = Somatic cell nuclear transfer-derived embryonic stem cell lines in humans: pros and cons | journal = Cellular Reprogramming | volume = 15 | issue = 6 | pages = 481–3 |date= 2013 | pmid = 24180743 | doi = 10.1089/cell.2013.0054 }}</ref>
