Stem cell research is one of the important scientific and political issues of these modern times. The purpose of this sample essay, one of the many writing services offered by Ultius , is to develop a historical and scientific overview of this selected issue. The essay will begin with a general introduction to stem cell research. Then, it will discuss the scientific history of stem cell research as it has unfolded over the past several years; and after this, it will turn to a consideration of the political history of stem cell research. Finally, it will provide a summary reflection on contemporary debates and conflicts that are currently surrounding the issue of stem cell research.

Olszewski et al , explains that due to their low proliferation rates and the over-expression of drug resistance proteins on the cell surface they are a very hard target to hit with traditional chemotherapies . Picture from Gene expression patterns of human colon tops and basal crypts and BMP antagonists as intestinal stem cell niche factors. Mutation starts early in colon cases taking many years to eventually turn into a malignant tumour. Changes usually start with a polypoid phase, with the loss or mutation of the Adenomatous polyposis coli APC gene, this is the trigger mechanism for further changes to occur.

Gene regulation is the process to know how cells control the genes.
The issue is really not about the stem cell research itself, but about how the knowledge might be used. Stem cell research has the potential to treat a wide range of medical problems. Disclaimer: This work has been submitted by a student.
