Embryonic Stem Cell Research Paper

Embryonic Stem Cell Research Paper-65
One report described the work of James Thomson and his co-workers at the University of Wisconsin, who derived h ES cells from a human blastocyst, comprising about 200 cells, donated by a couple that had received infertility treatments (Thomson et al., 1998).Their accomplishment was significant, because h ES cells are considered by many to be the most fundamental and extraordinary of the stem cells; unlike the more differentiated adult stem cells or other cell types, they are pluripotent.

There are important biological differences between embryonic and adult stem cells.The dual capacity of stem cells for self-renewal and for differentiation into particular types of cells and tissues offers great potential for regenerative medicine.The various types of stem cells differ substantially in these properties.A more likely benefit of the technology is that it would further facilitate a wide range of experiments to explore the underpinnings of genetic disease and possible forms of amelioration and cure, many of which would not be possible using h ES cells derived from blastocysts generated by fertilization (IVF), whose nuclear genomes are not defined.Although the promise of such research is as yet unrealized, most researchers believe that it will be a critical source of both important knowledge and clinical resources.In some countries there are statutory bans on the use of NT for reproductive purposes (see Chapter 4).Finally, promising research has been conducted with adult stem cells (Lanza et al., 2004; Wagers and Weissman, 2004).In addition to those research accomplishments, the cloning of Dolly the sheep in 1997 using a technique called somatic cell nuclear transfer or, more simply, nuclear transfer (NT), illustrated another means by which to generate and isolate h ES cells.h ES cell preparations could potentially be produced by using NT to replace the nucleus of a human oocyte, triggering development, and then isolating h ES cells at the blastocyst stage.However, in many other tissues, natural self-renewal appears to be a slow process, and stem cells for such tissues are correspondingly harder to characterize and isolate.There is also the possibility that some tissues may not contain a distinct subpopulation of undifferentiated stem cells at all.
