Stem Cells
Stem cells are the beginning of organism creation and have the potential to separate, becoming any kind of organism, endlessly. These cells have not gone through the process known as differentiation, which gives the cell a specific function. Technically, due to research over the recent years, scientists could grow certain organs with through stem cells because of the fact that these cells can be manipulated early on. There are multiple stem cells that have been determined and one of these cells is called a totipotent stem cell. This cell is the formed during conception (fusion of sperm and egg) and has the genetic code to make an entire being. In time, totipotent cells begin to turn into pluripotent cells, which are basically the same cells, but more specialized for parts of a being instead of the whole thing. Pluripotent stem cells, which are devoted to a specific cell line, cannot become less specialized once committed to the certain cell line. Stem cells, which are at the most fundamental stage in cell development, can be very helpful in determining how a cell becomes specialized in the cell making process. Diseases like cancer and birth defects are caused because of the incorrect cell division in specialized specialized cell. Knowing the process of correctly divided cells will help determine the mistakes in the cells that cause the diseases or birth defects, etc. This will allow the development of stem cell lines, which would decrease the amount of human and animal testing needed to get these results
As of now, the ratio of people needing transplantation to the organs and tissues available weighs heavily towards the need of the organ. Using the renewable source of stem cells, through cell lines, can reduce this. In order to make this successful, there must be extensive research done. This includes using living stem cells, potentially and probably, from human embryos. This is where ethics and science wages a war. You see stem cells
