In recent development a team of British researchers have come up with a groundbreaking medical treatment that could dramatically enhance the body’s ability to repair itself. This therapy involving the use of stem cells, makes the body release a flood of stem cells into the bloodstream. This goes on to heal even the most serious of tissue damage caused by heart attacks and even repair broken bones.
When the body is injured, the human body initiates the bone marrow to release stem cells that home in on the damaged area. When they arrive, they start to grow and produce new tissues, which build upon to constitute heart cells, blood vessels, bone and cartilage.
Scientists already know how to make bone marrow release a type of stem cell that can only make fresh blood cells. The technique of stem cell therapy is used to collect cells from bone marrow donors to treat people with the blood cancer leukemia.
Work on Stem Cell Therapy
Now a team led by Sara Rankin at Imperial College London has discovered a way to stimulate bone marrow to release two other types of stem cell, which between them can repair bone, blood vessels and cartilage. This has huge and broad implications. Explained with an example wherein a person supposes comes in to hospital and has had a heart attack. When such cases are administered these drugs in stem cell therapy they allow the stem cells to be quickly released into the blood thereby accelerating the repair process.
The body repairs itself all the time and that too on its own. The skin heals over quick and easy when we cut ourselves . Similarly, inside the body there are stem cells patrolling around and carrying out repair where it’s needed. However, when the damage is severe, there’s a limit to what the body can do. It is in such cases that we might need to stimulate the production of stem cells by means of effective stem cell therapy to help the body heal quickly.
The human stem cell therapy involving the use of stem cells can also prove useful in treating patients with immune disorders, such as rheumatoid arthritis. One of the human stem cell types released from bone marrow dampens down the immune system, and so could help keep so-called “autoimmune” diseases under control.
A possible danger with some other stem cell therapies in the pipeline is their use of embryonic stem cells. This is because these embryonic stem cells can over a period of time turn into any type of tissue; there is a risk they could grow into cancer cells when injected into patients.
