If we think of our body as a repair shop that naturally fixes ‘its own broken parts, stem cells are the body’s repairmen.
They can turn into different types of cells to fix specific problems.
Mesenchymal Stem Cells are considered as super repairmen because they can turn (differentiate) into body tissues such as bone cells, cartilage cells, or fat cells, depending on what is needed. When applied to a skin burn, they become transformed into the cells needed to fix the wound.
However, Mesenchymal Stem Cells (MSCs) do more than just change into needed cells. They also release substances that help create a healing environment. They encourage other cells to grow and form new blood vessels, help reduce inflammation, and keep scars from forming too much.
For people with burns, this treatment speeds up healing, helps grow new skin and tissue, and improves the look and function of the skin after it has healed. The results from the clinical use are exciting, and hopefully many more wounds which would have festered till death can be treated effectively in unprecedented ways. Thank you very much.
The Power of Stem Cells
As a general principle, stem cells have the ability to turn into any cell type in the body. Imagine having a tiny army of cells that can transform and replace damaged tissues – that’s the power of stem cells. The types which are located within the body’s connective tissue, also known as mesenchymal tissue, are called Mesenchymal Stem Cells. An example of this is the subset found within the umbilical cord tissue and blood. These stem cells from umbilical cord blood have unique advantages, a very important of which is their being safe for practically all recipients – known as ‘Immunological Safety.’
“Immunological safety” is a fancy way of asking, “Will the body of a recipient reject these cells when received?” This is an important question because when something foreign enters our body, our immune system usually jumps into action to defend us against potential threats. But with umbilical cord stem cells, the peculiar advantage lies in their ability to be accepted by recipients more easily than other cells. They’re like universal donors – adaptable and less likely to cause immune reactions.
The Advantage for Regenerative Medicine
These cells are being applied in Regenerative Medicine to treat various diseases and conditions, particularly with degenerative components. These conditions range from heart disease to degenerative brain diseases, brain and spinal cord injuries, kidney diseases among others. With umbilical cord stem cells, treatments are more effective and safer.
In Conclusion
The Umbilical cord tissue and blood is a source of powerful stem cells with the peculiar advantage of “universal safety” and therefore is being widely applied in regenerative medicine.
