A stem cell is a cell that has capability to be developed into any type of cell, These cells also have the ability to regenerate for a prolonged period of time in order to produce either more stem cells, or specialized cells for the body.
Where do stem cells come from?
• Embryonic stem cells.
These stem cells come from embryos that are three to five days old.
These are Pluripotent stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
• Adult stem cells.
These stem cells are found in small numbers in most adult tissues,
There are four part of our human body that known as accessible sources of adult stem cells in humans:
1. Bone marrow
2. Adipose tissue (lipid cells)
From a lot of research there has already found that Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.
• Perinatal stem cells.
This type of stem cells come from amniotic fluid in addition to umbilical cord blood stem cells. These stem cells also have the ability to change into specialized cells.
