How Stem Cells Help the Healing Process
When stem cells are injected intravenously, intramuscularly or subcutaneously, they travel to those parts of the body that have suffered from some type of injury. At these various sites of injury, the blood vessels have been damaged, narrowed and constricted. These constrictions prevent the oxygen carrying red blood cells from passing through to the tissues - which then produce areas of reduced oxygen content. Since stem cells are large, they become lodged in these narrowed and constricted small blood vessels. The low levels of oxygen found in these damaged areas are just what the stem cells need to grow and multiply.
As the stem cells grow in the damaged, hypoxic (lack of oxygen) tissue areas, they gradually become stimulated by their surrounding cells and environment to become new cells similar to those cells they come in contact with. As they grow and become specialized, they are able to transform into new blood vessels, neurons, muscle, eye, pancreas, kidney, liver, bone marrow, etc., depending on the local tissue influences.
In the early stages of human development prior to the first cells becoming specialized, the stem cells develop best in a low oxygen environment. As the embryo grows and the stem cells become specialized, they begin to require more and more oxygen. The more specialized, the more oxygen. For example, the brain is the most specialized organ of the body, using 20% of the oxygen consumed by the body while only being 2% of the body weight.
Whether the health challenge is Alzheimer's Disease, Stroke, Traumatic Brain Injury, Cerebral Palsy, Spinal Cord Injuries, Parkinson's Disease, Heart Disease, Diabetes, Cancer, Blindness, Immune dysregulation or genetic abnormalities, the results of animal and human studies using human umbilical cord stem cell treatments are very exciting:
