When stem cells are injected into the blood stream, into your muscles, they travel to parts of the body that have
suffered from an 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 going in to the tissues - which then produce places of reduced oxygen
content. Since stem cells are big, they become lodged in these tight and constricted small blood vessels. The low levels of oxygen
found in these damaged areas are just what the stem cells need to improve and grow. As the stem cells grow in the damaged areas, they gradually become influenced by their surrounding cells and environment to become new cells similar to those cells they come in contact with. As they grow and become specific, they are able to transform into new veins, neurons, , bone marrow, muscle, eye, liver, kidney, etc., depending on the area where they are injected.
In the first stages of human development prior to the first cells becoming specialized, the stem cells develop best in environment with low oxygen. As the embryo grows and the stem cells become specific, they begin to require more oxygen. The more specialized, the more oxygen they need. For example, the brain is the most specialized organ of the body, using 20% of the oxygen consumed by the body while only being two percent of total body weight.
Whether the health challenge is Alzheimer's Disease, Stroke, head/brain Injury, Spine Injuries, Heart Problems, Diabetes, Parkinson's Disease, Cancer, Blindness, or any genetic/muscular abnormalities, the results of many human and animal studies using human umbilical cord stem cell treatments are very promising and a look into the future.
