There are many rumors about cord blood on the Internet, such as:
The amount of cord blood is not enough and can only be used for children. Umbilical cord blood cannot be used by itself, it is used by others. Autologous cord blood cannot cure congenital diseases.
The water is too deep.
It sounds quite true, the three become tigers, and many parents are suspicious of "the cord blood seems to be very tasteless".
Is it true? How true or false are the online rumors?
Cryolife believes that these rumors are not difficult to explain. Asking experts is the most convenient way. The words of top experts in the industry from Beijing Concord International are obviously very valuable.
Just this year, Wang Jingxing, a researcher at the Chinese Academy of Medical Sciences and a professor of biochemistry and molecular biology at Peking Union Medical College, was a guest of "Chengdu Full Contact", and the host asked these questions.
Professor Wang did not hesitate, and gave the answer categorically: all wrong!
Umbilical cord blood is the blood that remains in the umbilical cord and placenta when the fetus is delivered. It contains hematopoietic stem cells that can rebuild the human hematopoietic and immune system. It is a very precious life resource.
Question 1: Is cord blood only used by children?
Professor Wang said: This statement is simply unrealistic.
With real data, you can slap your face. Both the International Center for Blood and Bone Marrow Transplantation and the European Cord Blood Transplant Registry data show that adult cord blood transplants are also on the rise. After 2008, the number of transplants per year even exceeded that of children.
The fact is that more and more adults are receiving cord blood transplants. Why can it only be used for children?
According to Sichuan data, as of March 31, 2020, adults accounted for 55.96% (age ≥ 18 years), of which the oldest patient was 68 years old; patients weighing more than 50 kg accounted for 51.39%, of which the oldest patient reached 110 kg.
110 kg patients can use it, is there any problem with insufficient amount? Obviously not.
More importantly, cord blood technology (collection, cryopreservation and pre-transplant pretreatment technology) is still evolving. The problem of the amount of hematopoietic stem cells has been improved.
At present, there are more than 50,000 cord blood transplant cases worldwide, and more than 12,000 cord blood transplant cases in my country.
What do you say can only be used by children? The rumors are self-defeating.
Question 2: "99% of the products used are cord blood from others", is this statement correct?
Professor Wang also gave a solemn negative.
The family’s own cord blood can be used by the child or family members.
Moreover, the HLA matching between the parents and the child is half-matched, and there is a 25% chance that the siblings are completely the same, and the matching success rate is much higher than that of strangers.
As early as 1992, the United States established the first and the world's first autologous cord blood bank CBR (Cord Blood Registry). It is to save it for its own use, and operate it till now.
If you save it yourself and you can’t use it yourself, how can so many families stupidly save it.
Just think about it, and you will find this kind of rumors very ridiculous and unfounded.
The self-use cases can be cited at hand:
In July 2010, a 5-year-old child with neuroblastoma successfully completed the first autologous cord blood transplant in Sichuan Province.
In 2019, the Guangdong Provincial Maternity and Child Health Hospital used self-storage cord blood to treat cerebral palsy for children with Jiangyou, which is also autologous cord blood.
In short, it can be used by itself, as are its parents and compatriots, and the chance of matching success is very high.
Professor Wang resolutely rejected Internet rumors and affirmed the value of cord blood.
The story of the trio becoming a tiger has existed since ancient times. You don’t listen blindly, and you trust industry experts to avoid being deceived and make choices that are truly beneficial to family health.
Question 3: Autologous cord blood cannot treat congenital diseases, so self-preservation is meaningless?
Professor Sun Yuan, deputy dean of Beijing Jingdu Children's Hospital and director of the Hematology Oncology Center, once answered this question.
