AC DC Adapter [new] father hand ยท why I donate cord blood
Waiting for fly when you were born, the nurse brought a stack of "don't gifts cord blood" form. Not to donate, it doesn't matter; To donate, just fill out a form, so that she will according to the completed form notice to prepare deliver doctor.
So, "cord blood save" this thing again into my brain.
A few years ago waving was born, a friend asked me: cord blood preservation have no? According to his statement, there is a propaganda save the importance of umbilical cord blood, does not leave the money spent is embarrassed to say "hello" - now that the children are so precious, if not for the children to buy this "life insurance", always feel oneself irresponsible, and even a little bit guilt.
He is a wage-earner, save the fee although umbilical cord blood can bear, but is not easy. But compared with costs, he was more concerned about is: this thing has many USES and save how high reliability.
I said heard of it, but an obstetrician and pediatricians are not advised save, I just looked at the introduction, also feel not necessary, there is no save. As for the reliability is not problem, technically, long-term preservation blood difficulty is not great. Because I didn't sell personal point of view hobby, also didn't ask he finally made the pen "life protection money" no.
I asked the nurse what is the form. She said that umbilical cord blood bank collection of umbilical cord blood. With blood donation, if willing to fill out a form, the child was born after the obstetrician umbilical cord blood collected to the blood bank. The blood will be offered to the public or research institutions use. If not, don't have tube, the umbilical cord directly away.
As two in the biomedical field was edge "scientific people", the child's mother and I to build such a public umbilical cord blood bank is fully supported. Then fill out a pile of form.
But I was curious: the doctor did not introduce us to save cord blood for their children. The fly was born after, I can't help but inquiry about the reason.
Stem cell transplantation is the modern medicine a very popular topic. For many blood and genetic disease, stem cell transplantation may be help means. And was going to throw away the cord blood contains quite a number of hematopoietic stem cells, and does not exist the problem of matches, so when the baby is born is regarded as precious "by-products". (from other people's stem cells exist "type-specific failure" risk, a person with brothers and sisters matches the possibility of success is 25%, and the possibility of successful matches with others is more low.
"His umbilical cord blood never matches, failure to preserve their own umbilical cord blood, for future one thousand" became a preservation of cord blood "theoretical basis", has become many commercial preservation institution propaganda appeal.
However, the American academy of pediatrics don't recommend hold yourself cord blood. They think, "save cord blood" marketing mode is mainly in the use of child birth parents susceptibilities to get identity, but in which conceals the fact that many.
In the announcement of the American academy of pediatrics, the experts pointed out: use their own stem cells to treat disease is still the main is a kind of idea, not reality.
- although technically possible, some experiments also show that such therapy in the future may become a reality, but the "future" how far is it?
Those who save blood institutions often claimed near at hand, scientists did not so optimistic.
In addition, the number of umbilical cord blood is limited, usually only a few tens of ml. The dozens of ml of umbilical cord blood, including the number of stem cells, only enough for children transplantation,
This means that the insurance should play function, can be in only a limited period of efficacy, and the validity, there is no commercial ads describe so long.
Although the future development of the medicine may reduce the umbilical cord blood volume requirements, but it also is a kind of is not scientific progress support "hope". The most important thing is, there is no scientific data to support the "use your own umbilical cord blood is a effective".
Business promotion, starting point is only "own cord blood no type-specific risk", but to avoid another problem: if the disease is from genetic factors - this is very common in the blood (such as leukemia) - then his umbilical cord blood stem cells will also carry the same genes, so does not really solve the problem.
From logic point of view, scientists may be able to solve the problem in the future, because we can't know the future development of medical association to what extent, cannot know the possibility can be realized, and when to realize. However, commercial organizations but "may" render a "reality".
Based on the present situation of the development of biological medicine, the bone marrow donation association (WMDA), the American academy of pediatrics (AAP) and the European Union are not encourage people to save cord blood "life insurance". These organizations believe that only when a child has the blood or genetic defects, save the same parents' other children's umbilical cord blood is considered to have practical significance.
The academy of pediatrics clear attitude, it's not hard to understand the doctors not for commercial save blood institutions do the selling. In the United States, if the doctor regardless of scientific facts and son medical association, the announcement for commercial save blood institutions do marketing, will be treated as a violation of the professional standard. If the doctor from save blood institutions have a benefit, then the problem is more serious.
Whether waving or fly, from pregnant to was born ten months, we have not received the publicity of umbilical cord blood preservation.
Even to public umbilical cord blood bank, hospital also didn't do any tendentious introduction, it's only a mention lightly to inform the we have so one thing only. After donation, to not have any personal benefits, only from a blood bank card. Doctors and hospitals also can't get what interests - blood bank will take blood for the doctor to provide a service fee, but it is said that most doctors also give up, and take blood work as a kind of public welfare.
In fact, there are a lot of umbilical cord blood stem cell transplantation in the treatment of successful report, but these stem cells, and not from their own umbilical cord blood.
This is about to say: why should I donated cord blood?
Because I know, the establishment of public umbilical cord blood bank meaning lies in the society, make most of the cord blood have entered the public "umbilical cord blood bank", although not related person matches, the successful probability is very low, but as long as optional sample size is very big, there are still a large type-specific success may be. This is a very simple arithmetic: even if foreign matches the probability of successful low to one over ten thousand, but as long as there are 100000 optional sample matches, the chance of success is considerable.
Unfortunately, when foreign donation cord blood become mainstream, we still stay in "for his hopes" the propaganda of well.
