Stem cells come from two main sources:
- Embryos (embryonic stem cells).
- Adult tissue (adult stem cells).
Both types of cells are categorized by their potential to differentiate into different cell types, such as, skin cells, muscle cells or bone cells.
Embryonic stem cells: These stem cells come from embryos that are about 3 to 5 days of age. At this stage, an embryo is referred to as a blastocyst and has an estimate of 150 cells. The blastocysts are pluripotent stem cells. Pluripotent means that the cells can divide into more stem cells or can become another type of cell in the body.
Adult stem cells: These stem cells are found mostly in the bone marrow. Adult stem cells have a limited ability to give growth to various cells of the body. Adult tissues cannot divide themselves until they are triggered by disease or tissue injury.
Stem cells are able to treat a wide range of different diseases, whether a heart disease or an injury. In a stem-cell transplant, stem cells are able to replace tissue that is a damaged by disease or injury.
Leukaemia is a cancer of the blood or bone marrow. The bone marrow creates blood cells, so leukaemia can happen when there is a problem with the creation of blood cells. The white blood cells in the body are affected when these is a problem in the production of blood cells. Leukaemia occurs when the DNA of blood cells becomes damaged. When this happens, blood cells grow and divide endlessly, and then there are just too many blood cells and this becomes a problem. The healthy blood cells all die out and are then replaced by the new cells which are the bad cells. Whilst the healthy blood cells are dying out, the abnormal blood cells do not die, they actually keep increasing and they then occupy the whole space, leaving no space for the healthy cells. So now the blood is occupied by the abnormal blood cells. Stem Cells And Leukemia Treatment
