Embryonic Stem Cells Essay

The difference between embryonic stem cells and adult stem cells is that an embryonic stem cell is not fully developed and with no specific cell tissues. Embryonic stem cells are found in the inner cells mass of the early embryo. The very first embryonic stem cells are totipotent (can be able to create all kinds of cells) but the rest after that are pluripotent which means that it can create many different types of cells such as white blood cells, nerve cells, and neurons. Adult stem cells are less flexible than embryonic stem cells. Bone, fat, cartilage, tendon, and muscle could all be made from adult stem cells. The adult stem cells are multipotent which means that they can form some kinds of cells in the body. Adult stem cells that are specialized with one type of cell usually only create only the type of cell related to the specific tissue.
Totipotent cells can form all of the cell types in the human body.
The only totipotent cells are the embryonic cells created within the first few cell divisions. The totipotent stem cells mature just days after fertilization. Multipotent stem cells have the same basic features. Adult stem cells are considered multipotent because there cell specialization is limited. Multipotent stem cells cannot make cells such as tendons. Pluripotent stem cells can, under the right circumstances differentiate into almost every cell in the body. This is the reason that they are often called “true” stem cells. About four days into the cell dividing process totipotent stem cells start to form specialized groups of cells making pluripotent stem cells. There are some pros and cons of stem cell research. A pro is that stem cell research can be helpful to many harmful diseases such as: Parkinson’s disease, Alzheimer’s Disease, and many others. Some cons include that abortion is an alternative plan to unexpected pregnancies in women who would have never thought of aving an
abortion.
