| What are Stem Cells? |
| |
| | Stem cells are the primary cells in human body and animals that have the ability to divide and differentiate into other types of cells. Research by Canadian scientists Ernest A.McCulloch and James E.Till in the 1960’s started interest in Stem cells worldwide due to some discoveries that they made.

| To put it simply, a human being already has stem cells, but sometimes they are damaged and either don’t grow or grow exponentially causing tumors and cancers. So injecting fresh stem cells in the area of the problem faced by the patient can cure him of the disease. For example, you have baldness, so stem cells can be used to replace the dead cells and create the necessary growth of hair again. |

| Stem cells exhibit the following main features : |
| |
- The ability to separate into specific cells.
- The ability to stimulate an infinite number of times.
- The ability to move and separate where needed.
|
| Thus stem cells are basic primary kind of cells. They eagerly wait for the signal to know what they will ultimately divide into, be it skin cells, or blood cells or even more complex cells. |
| |
| Stem cells are all not the same. Not all exhibit the same characteristics. The difference lies in their ability to form full fledged tissues, or differentiate into multiple cells . This peculiar ability or rather potency is the first way to know the difference between different types of cells. |
