*To Dr. Black, the use of embryonic cells ''fundamentally constitutes the gold standard'' in medical research because of their purity and versatility. But he cautioned: ''This is a very young field. Our areas of ignorance are far greater than our areas of knowledge.'' [http://query.nytimes.com/gst/fullpage.html?res=9500E3DD1739F93BA25752C0A9629C8B63&sec=&spon=&pagewanted=print]

==Inducible Pluripotent Stem Cells==
Research in 2006 has facilitated the conversion of human adult somatic cells into pluripotent stem cells, namely possessing an ability to differentiate into many types of tissue. (Unlike embryonic stem cells from blastocysts, however, IPSCs are not totipotent.) By forcing the expression of certain genes, via the activation of many transcription factors (such as tetramer and hexamer TFs), using a particular medium (e.g. HIF and LIF), pluripotent stem cells can be generated. This research has great potential on account of its ability to resolve the dilemma surrounding the use of embryonic stem cells.
