Task1

Accordingto Lanza &amp Atala (2014), embronic stemcells(ESCs) are biological cells that are obtained from the inner cells ofan embryo that do not have the ability to grow. The ESCs grow to formthe three germ layers namely mesoderm, ectoderm, and endoderm. Stemcells are undifferentiated biological cells that have the capacity togrow and generate more cells(Lanza&amp Atala, 2014).

Task2

Ithink Raina vote for the Proposition 71. I would also have voted forthe proposition. The reason behind my choice is because of ESCs havesignificant benefits such as treatment for diabetes. Looking atethical principles does not prove to be a good reason to vote againstthe proposition. The stem cells are largely obtained through avoluntary process. It is thus appropriate that we encouragescientists to engage in more studies that will reduce human suffering(Koka,2008).

Task3

Currentresearch on ESCs has led scientists into undertaking experiments thatwould minimize the controversies surrounding this technology. Stemcells can now be obtained from the umbilicalcord blood and other body tissues.Scientists are currently creating stem cells by utilizing the somaticcell transferapproach. It is through similar researches that scientists haveconducted experiments on human cloning using this technology(Freedman,2007).

Task4

Thebenefits arising from the stem cell research outweigh the ethicalconsiderations. Studies indicate that stem cell therapy can be usedin the treatment of certain lifestyle diseases such as Alzheimer`sdisease and diabetes (Panno,2005).

Task5

EScell has limited life span since the embryo from which it is obtainedhas not yet developed fully. In fact, they disappear gradually as theembryo develops. Further, the cell cannot easily withstand theconditions that support it during the experimentation process (Snow,2003).Task6Therapeutic cloning is the removal and transfer of a nucleusthat has genetic material to an un-fertilized egg whose nucleus hasalso been eliminated. I would support the process to help in theproduction ES cells that can be used in the treatment of diseases. Ithas great importance in the cell replacement therapy (Atala&amp Lanza, 2011).

Task7

Adultcells are now being reprogrammed to create pluripotentstemcells.iPS cells behave differently compared to the ESCs cells. Currentresearch studies on iPS cells are largely based on how the cellsbehave in case a disease attacks the body (Rogers, 2011).
