Human embryonic stem cells (hESCs), owing to their potential promise to develop into any somatic cell type, have radicalised biotechnology research and application in clinical medicine. The source of hESCs has traditionally been viable cells retrieved from preimplantation stage embryos grown in culture ...
The importance of ethical issues is often understated in public knowledge. Embryonic stem cell research should be of the utmost importance in the American society due to increased federal funding and the promises research in this field hold. As with many other controversies, embryonic stem cell res...
The Ethical Dilemma of Embryonic Stem Cells “Now science has presented us with a hope called stem cell research, which may provide our scientists with many answers that have for so long been beyond our grasp.” (Nancy Reagan). Most cells within our bodies perform one specialized task. Contra...
The use of human embryonic stem cells (hESCs) in cell replacement therapies (CRTs) has been limited due to several technical and ethical issues. Since its inception there has been an extensive debate about the benefits and drawbacks of adult vs hESC use in therapies [6, 7]. For hESCs the...
named inducedpluripotent stem cells(iPSCs), behave similarly to hESCs and can be differentiated to desired cell types from all three primary germ layers. As generation of humaniPSCsdoes not involve the destruction of human embryos, using human iPSCs for regenerative medicine avoids the ethical ...

The use of human embryos in human embryonic stem cell (hESC) research raises significant ethical and policy issues associated with their donation. Recent research conducted in several countries assesses the percent of persons with cryopreserved and fresh supernumerary embryos willing to donate them for...
3 Embryonic Stem (ES) Cells 胚胎干细胞 Derived from early embryos (Inner Cell Mass 内细胞群 ) Advantages 优点 Easy to isolate 容易分离出来 Show full potential for all cell types 可分化成所有种类细胞 Extended cell growth capabilities 扩增的细胞生长能力 Disadvantages 缺点 Significant ethical issues ...
Human embryonic stem cell research offers great promise for the treatment of many serious disease conditions in a variety of medical areas, including wound healing. Before this promise can be realized, society and individual researchers, clinicians, and patients will have to answer four ethical ...
Human embryonic stem cell (hesc) research is the culmination of a multi-step process: creating an embryo through in vitro fertilization (IVF), deciding whether to donate or destroy embryos "left over" from that process, harvesting stem cells from embryos donated for research, and finally doing...
