In previous posts we covered how stem cells treat a variety of ailments ranging from back pain to paralysis. These articles also shed light on how stem cells have become an alternative source of medicine for people who would rather not undergo surgery. Stem cell treatments are far less intrusive and a much safer option.

While we've already provided at least two answers as to why scientists are interested in studying and using stem cells, here are some more:

1. Better understand how diseases occur

By studying stem cells, scientists are forced to watch cells grow, mature and split. They observe stem cells morph into cells for bones, muscles, organs and tissue. By observing this phenomenon, they can better understand how diseases and conditions develop. In turn, they'll be able to better treat them.

2. Create new cells

Stem cells have the unique ability to transform into other cells or stay as is. When they change into other cells, scientists can replace diseased cells with these new ones. For example, scientists are currently examining how stem cells may play a role in Alzheimer's treatment by studying whether stem cells can replace damaged brain cells.

3. Test drugs

Before drugs hit the market, scientists often test their safety by using stem cells. Of course, for the medicines to be safe and effective, the stem cells must change into the cells the medicine plans to treat.

As you can see, there are many different ways to use stem cells to treat diseases and conditions. This will only grow as more research is conducted.
