Three Methods Of Embryonic Stem Cells

Within the last decade modern science has made an incredible breakthrough on re-growing damaged parts of the human body. Being able to regrow damaged cells sounds whole heartedly good. Although many people are against it because of how they repair the loss or damaged cells. To be able to repair damaged cells scientist must first obtain stem cells. Stem cells can be obtained three ways. First by reverse engineering the cell, this type of stem cell is called a pluri-potent cell. The second way is by borrowing some of the adult’s stem cells thus comes the name Adult stem cells. The last method is the method that gets the most ridicule, this method is where they take stem cells out of the embryo and use them to repair or grow cells (Zusi). As a research poll conducted at Montgomery high school showed most people think that the most common type of stem cells are embryonic. Although embryonic stem cells are common, they are not the most common. The most common type of stem cell is in fact pluri-potent stem cells.

Pluri-potent stem cells are widely used in the genetics community to cure many different diseases. Pluri-potent cells are formed when an adult somatic cell is taken and is reverted back to a baby cell.

Scientist are able to differentiate between four cells in the fetus. The four cells are mesendoderm, trophoblast, mesenchymal stem cells, and neural progenitor cells. Mesendoderm cells are the inside tissue of the fetus. The second cell is trophoblast, this cell helps nourish and care for the fetus as it develops the placenta. Another cell is the mesenchymal stem cells, they develop into cartilage then into bone as the fetus develops into a newborn. The last cell is neural progenitor cells, they cell keeps track of what genes were trabnscribed into what cell type, as well as remodel and construct DNA methylation
