Essay On Stem Cells - 1148 Words

So basically I’m gonna summarize an article and it’s about the genetic profiling of putative breast cancer stem cells from pleural effusions. The authors of this article used this opportunity and found out that pleural effusions were great opportunities to be able to study metastasis and for isolating stem cells. The doctors basically isolated the cancer stem cells(csc) and the non cancer stem cells(non-csc) and were able to derive how fast these stem cells were able to form. At the moment breast cancer is the leading cause cancer related deaths in females. This mortality rate seems to stay around the same due to something called cancer metastasis(the growth of another cancerous tumor away from the primary tumor. And for this reason they†¦show more content†¦So scientists basically separate all the cells from a clump and let them float in some liquid. After a while the fast developing cancer cells will begin to duplicate at a fast rate while normal cells would do that at a slower rate. Scientists later then sorted out the CSCs (cancer stem cells) and tested them for ALDH1. But most of these tests came back with some negative results as they had been detected in some pleural cells but only had a median detection of 2.7%. So they then used a CD44+CD24 detection sample and they were able to evaluate 13 out of 18 pleural effusions (72%). (Defining CD24- a heat stable antigen found on the surface of a cell CD44- hyaluronic acid receptor) These tests were done until sample 13 because after sample 13 they added optimization steps which included having the samples filtered through a wide mash and then filtered through another filtration strainer after the lysis step. These received better results with the unsorted cells instead of the sorted cells which made mammospheres. Defining what the tables and pictures say. On page 6 there is a table with 25 examples of tested pleural cells it also shows their ages and they’re somewhere between 91 and 49. next column shows Her2(human epidermal growth-factor receptor 2) and that is a a protein and can be found inside cancer and normal cells. If found this protein can help determine which kind of treatment is best for the patientShow MoreRelatedStem Cells Essay1699 Words   |  7 Pageshas provided us with a hope for these diseases. This essay will address the issue of controversial research in stem cells. This technology offers hope to millions who are victims of a multitude of diseases and disorders. It can be used to regrow limbs, create organs, attack genetic diseases, treat malfunctioning bladders, etc. However, this same technology is also one of the most controversial debates in science today.

Research in the use of stem cells holds limitless possibilities in the medical field. Stem cells are the cells in our bodies that are in their primitive form. These cells have not yet become the type of cell they are destined to be, whether it be nervous tissue or another. However, even though stem cell research is a great new field, its progress is being limited by moral concerns and ethical questions. In order to let medicine reach its full potential, stem cell research should be legalizedRead MoreStem Cells Essay1530 Words   |  7 Pages Stem cells are used every day throughout the United States to help cure diseases and save lives. Stem cells can also be used to study labor defects so that future birth deficiencies can be prevented or reversed. Although as a college student starting a family may not be on your mind yet, it is always beneficial to educate yourself on current trends and new discoveries in stem cell research.

Without a doubt, hair is a an overlooked vital aspect of daily life. At birth, hair follicles are developed and undergo a total of three phases: anagen, catagenRead MoreStem Cell Essay939 Words   |  4 PagesInduced Pluripotent Stem Cells and their use in Cardiac Regeneration Introduction Myocardial infarction (MI) is the leading causes of mortality and morbidity in the world. Ischemic heart disease, where the oxygen supply to the myocardium is restricted, is a common cause of an MI. Myocardial injury results in loss of cardiomyocytes (cardiac muscle cells) due to apoptosis, and the development of necrotic myocardium, eventually leading to heart failure. The formation of the necrotic myocardium causesRead MoreStem Cell Essay1061 Words   |  5 Pagestreated with the use of embryonic stem cells. Embryonic stem cells are cells derived from the undifferentiated inner mass cells of human embryo. In simpler terms, these cells have the ability of developing into any of the two hundred different cell types in our bodies. Unlike most of the cells in our bodies, such as heart cells or skin cells, which conduct a specific function, a stem cell does not have a specific function until it is specialized (Hogan). A stem cell that is becoming specialized willRead More Stem Cells Es say1128 Words   |  5 PagesEmbryonic Stem Cells â€Å"Embryonic stem cells...are in effect, a human self-repair kit,† (Christopher Reeve, activist – Larry King show). For the advancement of science, stem cells are infinitely valuable, especially when considering all the potential applications in the field of medicine. Stem cell usage is a very controversial topic, because most people think of abortions, cloning, and other negative topics when they hear the term stem cell.

They are cells that exist in an undifferentiated state, and transform into differing tissue types depending on what the cells surrounding them are. The different types of stem cells have the ability to repair many classes of damaged human tissue. However, only one type of stem cell promises to regenerate virtually any class of tissue.
