CORD BLOOD STEM CELLS: AN IMPORTANT CELLULAR SOURCE FOR TREATING STROKE
Stroke is today one of the major challenges for modern medicine, as our brain has a very limited natural ability to repair damage to nervous tissue. However, scientific research is opening a new and exciting frontier: the use of umbilical cord cells to regenerate neurons and restore autonomy to patients. Two recent clinical studies show that this biological resource can be decisive at two different moments in the course of treatment.
The acute phase: timely intervention with mesenchymal cells
The first crucial step takes place in the hours immediately following the event. A clinical trial tested the use of mesenchymal stem cells derived from cord tissue (product UMC119-06) on patients treated between two and seven days after stroke. The results indicate that this treatment is not only safe and well tolerated, but also shows signs of extraordinary efficacy. Through magnetic resonance imaging, researchers observed a significant reduction in the volume of brain damage. These cells act as an “emergency response centre” that migrates to the damage, reducing inflammation and promoting the growth of new blood vessels, thus accelerating the return to independence in daily activities.
The recovery phase: enhancing rehabilitation with cord blood
The support provided by the umbilical cord does not stop at the emergency stage. A second study focused on the “subacute” phase, i.e. the critical period between one and nine months after the stroke, when most of the motor recovery takes place. In this case, umbilical cord blood was used in combination with erythropoietin (rhEPO), a hormone that protects neurons. Six months after treatment, patients who received this therapeutic “combo” showed clear improvements in motor function and a greater ability to perform everyday tasks compared to those who underwent standard rehabilitation alone. A surprising finding also concerns the psychological aspect: the treatment led to a significant reduction in depressive symptoms, which are often common after a stroke, improving overall quality of life.
Synergy for the future of the brain
Together, these studies tell us that the different components of the umbilical cord — tissue cells and blood cells — can work synergistically to protect the brain immediately after the attack and help it rebuild itself in the following months. Thanks to their “young” nature, these cells have a greater regenerative capacity than those taken from adult individuals and present an almost zero risk of rejection.
Why it is essential to preserve the umbilical cord
In light of these discoveries, it is clear that the umbilical cord is much more than a biological link between mother and child: it is a real biological insurance policy for the future.
Preserving umbilical cord blood and tissue means preserving an invaluable source of young and powerful stem cells, ready for use in regenerative medicine therapies. In a world where science is learning to repair complex organs such as the brain, deciding not to discard this “treasure” is a forward-looking preventive measure that can make a difference in the treatment of serious and disabling diseases, offering real hope for recovery and a better quality of life.
