There are so many usage of umbilical cord stem cells, it will be needs more than a year to explain the question of what are umbilical cord stem cells used for, but we will review it here for just a little part of it. Cord blood comes from a newborn’s umbilical cord and can be collected immediately after birth. It contains powerful stem cells that have been used to regenerate healthy blood and immune systems. So far, cord blood stem cells have been used in more than 35,000 transplants worldwide. Doctors are also researching cord blood as potential treatment for conditions that currently have no cure, especially for the patients with terminally illnesses. Cord blood is used to treat children with cancerous blood disorders who’s in a serious illnesses condition, such as genetic blood diseases or leukemia. The cord blood is transplanted into the patient, where the HSCs can make new, healthy blood cells to replace those damaged by the patient’s disease or by a medical treatment such as chemotherapy for cancer. In this way, cord blood offers a useful alternative to bone marrow transplants for some patients. It is easier to collect than bone marrow and can be stored frozen until it is needed. It also seems to be less likely than bone marrow to cause immune rejection or complications. This means that cord blood does not need to be as perfectly matched to the patient as bone marrow (though some matching is still necessary to reduce the side effect including allergy and rejections).
Scientists believed that A major limitation of cord blood transplantation is that the blood obtained from a single umbilical cord does not contain as many haematopoeitic stem cells as a bone marrow donation, this is the main reason that treating adult patients with cord blood is so difficult: adults are larger and need more HSCs than children. A transplant containing too few HSCs may fail or could lead to slow formation of new blood in the body in the early days after transplantation. Some researchers have also tried to increase the total number of HSCs obtained from each umbilical cord by collecting additional blood from the placenta. This serious complication has been partially overcome by transplanting blood from two umbilical cords into larger children and adults. Neither solution is entirely satisfactory.
Current research is establish the safetyness and effective treatments for non-blood diseases could be developed in the future using cord blood. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. The point right now is how to do our best in our own way to support the research in stem cells development to found the new way in cured diseases especially for terminal illnesses. So instead of become a medical waste, it’s better for all of us to save our newborn baby’s cord blood, If it’s not collected at birth, your child’s cord blood will be discarded as medical waste. For that reason, most states follow the Institute of Medicine’s recommendation that expectant parents receive balanced educational information about cord blood banking options.
