The True Story of Stem Cell Research

There has been much talk in the press recently about the pros and cons of stem cell research. What is stem cell research?, what are stem cells, and how will it effect me? All the following will be explained in the following documentation. Well, first off stem cell research is the study of stem cells and how they can be used to benefit human organisms. Stem cell research is a fairly new technology humans have founded. The purpose of this research is to understand and experiment the new formation of stem cells in the human body. Thus , if understood many scientist can create cures for heart diseases, diabetes, create new organs so that if donors aren’t present new organs would be available. In the treatment of cancer, cells can be destroyed by radiation from chemotherapy can be replaced with new healthy stem cells that adapt to the affected area, whether it could be part of the brain, heart, liver, lungs, or wherever. Dead cells of almost any kind, no matter the type of injury or disease, can be replaced with new healthy cells thanks to the amazing flexibility of stem cells. So now you may wonder what stem cells are. Stem cells are cells found mostly found in most multi-cellular organisms. They are well known for their great ability to split and multiply through the presses of cell division and that these cells are sent and used thought the body to repair and fix broken or damaged tissue, but where can u extract them from. There are two main ways to obtain stem cells one is to harvest then from adult tissue and the other is to extract them from blastocysts to get embryonic stem cells. Another 2 types of stem cells are Fetal stem cells which are stem cells taken from aborted fetal tissue, and Umbilical stem cells in which Stem cells are taken from umbilical cords.

The first thing is that the adult stem cells are harder to obtain from adult tissue , but embryonic stem cells are much easier to obtain and open a wider range of opportunity to create new, fresh cells. Stem cell can basically replace mostly every cell in the human body. If some part of you body is damaged the properties of stem cells will bind to pre-existing cells to form newer ones and replenish that part of the body. There are 220 types of different type of cells in the human body, and stem cells can replace all of those most efficiently .Embryonic stem cells can be taken from spare human embryos left over from fertility treatments, or from artificial cloned human embryos developed in the laboratory only days old. One method for making cloned embryos is called nuclear transfer. During this process, genetic material or DNA from a donor is inserted into an empty egg cell. After the resulting combines new cell has been activated it begins to divide, creating new cells and forming a cloned embryo, spreading to be used in a repetitive motion to divide the new cells. A great way to think of what a stem cell is that it is an empty un-programmed micro chip with underestimated possibilities. Also if a human is missing blood cells, stem cells provides the opportunity to create red blood cells, white blood cells, and platelets. Red blood cells carry oxygen from the lungs to all of the cells in the body, and then bring carbon dioxide back from the cells to the lungs to be exhaled from us. White blood cells attack infections caused by bacteria, viruses, and fungi. Lastly Platelets are parts/fragments of cells that close damaged blood vessels and help blood to clot, both of which are important in stopping bleeding internal and external as well. Scientists have intentions to keep continuing the research of stem cells, with issues of founding and peoples moral issues and opinions.
