They arent,
Actually, they are quite useful as they replace diseased cells when grown on a sick body part.
Stem cell therapy can help your body repair itself by using stem cells which can become any healthy type of cell. The cons of stem cell therapy are that many people think that it is unethical and it is difficult to harvest stem cells.
Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.
They are cut into two pieces
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
Stem cells are considered as undifferentiated cells. They will divide and divide forming more stem cells. The two main stem cell types are embryonic stem cells and adult stem cells. Only the embryonic stem cells can become any type of tissue. Embryonic stem cells have the potential to become any type of cell in the body. There is news as of 2015 that perhaps blindness can be cured using these embryonic stem cells.
stem cells can turn into any cell of the body and preform their function.
a zygote is a stem cell
A totipotent stem cell found in embryos.
stem cells are known as the "repair system for the body". That means they divide constantly taking place of other cells. Like if they was a bad cell then the stem cell would just take its place. Stem cells are amazing for solving diseases. That's why stem cell research is so important- scientists have already discovered that stem cells can cure more than 70 of the most major diseases. Its really incredible

A stem cell is a type of cell that doesn't have a specific function. The cells you normally think about make up parts of the body like the muscles (e.g., heart), brain, nerves, etc. Stem cells have the ability to divide into these cells with a function and replace damaged ones. They can also divide into more stem cells. The exploration and use of stem cells to replace damaged parts of the body is called stem cell research or technology.
