It’s a very great question for all of us which has already read and discuss about stem cells in the article before, what can stem cells cure in the future ? if you has already finished reading all of the article before, you will found the new methodology of treatment for diseases in the future, cause the possibility of stem cells therapy is very large which they can be any the kind of cells that they want. As we has already known that there are so many type of stem cells source, here we will take a closer look to umbilical cord stem cells, which is very great and minimize the debate among the stem cells research. Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989. The current challenges for cord blood research is how may it be used, now and in the future ?. After a baby is born, cord blood is left in the umbilical cord and placenta. It is relatively easy to collect, with no risk to the mother or baby. It contains haematopoietic (blood) stem cells: rare cells normally found in the bone marrow. Haematopoietic stem cells (HSCs) can make every type of cell in the blood : white cells, red cells, and platelets. They are responsible for maintaining blood production throughout our lives. They have been used for many years in bone marrow transplants to treat blood diseases.
Cord blood is used to treat children with cancerous blood disorders such as genetic blood diseases like Fanconi anaemia or even leukaemia. Several research teams have reported studies in animals suggesting that cord blood can repair tissues other than blood, in diseases ranging from heart attacks to strokes. 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.. These findings are controversial: scientists often cannot reproduce such results and it is not clear HOW cord blood may be having such effects. When beneficial effects are observed they may be very slight and not significant enough to be useful for developing treatments. If there are positive effects, they might be explained not by cord blood cells making nerve or heart cells, but by the cells in the cord blood releasing substances that help the body repair damage.
Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. 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. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments. The scientists believe that umbilical cord blood is an important source of blood stem cells and expect that its full potential for treatment of blood disorders is yet to be revealed. Other types of stem cell such as induced pluripotent stem cells may prove to be better suited to treating non-blood-related diseases, but this question can only be answered by further research, we always hope for the best future treatment to reduce the suffering of the disease especially the patients with serious illnessess.
