Stem cells and why they hold a great promise
Here are frequently asked questions about stem cells and a simplified guide on understanding why stem cells are now deemed very important in medical science.
Stem cells are the building blocks of life, they mature into bones, heart muscle, nerves, different organs, and tissues. Researchers and scientists have used stem cells as their basis to understand different types of diseases as well as the process of why humans age.
Healthy cells are now being used to replace diseased cells in what doctors would call as regenerative medicine. Stem cells are now guided to become specific cells that can regenerate and repair diseased and damaged tissues in people.
Who are the people that can benefit from Stem cell therapy?
The answer is anyone, this is because the potential of stem cell use is unlimited and every year researchers and scientists are discovering new ways to use it to solve many medical problems. Stem cells can benefit people who have spinal cord injuries, type 1 diabetes, Parkinson’s disease, Alzheimer’s disease, heart disease, stroke, burns, cancer, and osteoarthritis.
Stem cells can also be used to test new drugs, doctors would be able to know if a certain drug is responsive. They test it on mice before they declare it fit to use on humans.
Stem cells have specialized functions, they can divide to form more cells called daughter cells or they can become new stem cells.
Where do stem cells come from?
There are various sources of stem cells, there are stem cells that come from embryos that are three to five days old. At this stage, it is named as a blastocyst and it can contain around 150 cells.
When we say pluripotent stem cells this means that it can divide more stem cells or can become any type of cell inside the body. Embryonic cells are adaptable, easy to use in the body and could be used to repair tissue and organs with diseases.
What are Adult Stem cells?
Adult stem cells, on the other hand, are found in small numbers, they are usually found in the bone marrow or fat. Unlike embryonic stem cells, these cells have more limitations. However due to recent advancements in science adult stem cells are now explored for the ability to create different type of cells and not just blood cells. In current tests being conducted, adult stem cells are now tested in people who are experiencing neurological and heart diseases.
In recent developments, adult cells can now have properties that work like embryonic stem cells. This is because scientists have already transformed regular adult cells into stem cells that can reprogram themselves.
This new technique is allowing researchers to use reprogrammed cells instead of harvesting embryonic stem cells. There are still a lot of conclusive tests to be done by researchers when it comes to adult cells but they are achieving great strides.
While Adult stem cells are not as versatile compared with embryonic stem cells and they have limitations when it comes to treating diseases, researchers, however, have found that adult cells are more adaptable than they first suspected leading to higher hopes for a more extensive use of adult stem cells.
