Describe how stem cells have the potential to treat sick people. ( in scientific words please).
Assoli18 [71]

Stem cells are undifferentiated cells that have the ability to differentiate into any kind of body cells like muscle, skin, heart etc.

There is alot of research being conducted on the stem cells because they have the potential to treat almost any kind of disease. This is because they are embryonic cells that can be specialized into a person's any type of body cells. When stem cells are specialized into the any kind of body's cells like cardiac, muscular, they can repair all the damaged cells and replace them with the new and healthy cells.

Currently, they are being used to repair:

  • Nerve cells that are damaged due to some injuries like stroke, spinal injury,  Parkinson’s disease, Alzheimer's and other such neurological disorders.
  • They can repair insulin producing cells so millions of people can be treated against diabetes and other problems that arise due to diabetes like kidney and cardiac issues.
  • They have the ability to repair almost any kind of injured tissue.
  • They can provide clues of muscle re-pairment like how organs are repaired after an injury, trauma or problem like heart attack.
  • Stems cells can be used to make new drugs and minimize the side effect of the drugs.
  • This is a fascinating area of science that has the potential to repair any damaged organ of human without getting it replaced by a new one.

Hope it help!
