Is there a time limit for cord blood storage?

Yes, the blood needs to be stored within 24 hours after collection, and stored in a liquid nitrogen tank at -196 °C after cryopreservation, which can theoretically be stored for a long time. You can consult the Beijing Umbilical Cord Blood Hematopoietic Stem Cell Bank.

Umbilical cord blood as the name suggests is the blood that remains in the umbilical cord blood and placenta after the baby is delivered, in modern times when medicine is not yet developed, umbilical cord blood is discarded as a waste product at will, and with the continuous development of medical research, scientists have turned their attention to the umbilical cord blood, and found that umbilical cord blood contains abundant hematopoietic stem cells, and these stem cells have strong activity and proliferation ability, far more useful than stem cells in ordinary adults. Therefore, scientists have applied these stem cells to hematopoietic stem cell transplantation, and with success, umbilical cord blood is also becoming important for hematopoietic stem cells after peripheral blood and bone marrow**.

From the perspective of the role and effect of umbilical cord blood, the value of umbilical cord blood is beyond doubt. However, since cord blood can only be obtained within a few minutes of delivery, and if it is missed, it is highly desirable to preserve it for a long time. And with the continuous development of cell storage technology, self-storage of umbilical cord blood is gradually accepted by more and more expectant mothers, after all, umbilical cord blood is the first gift brought by the baby to this world, and there is only one storage opportunity in a lifetime, spending about 20,000 yuan to save the umbilical cord blood for the child's future health backup, isn't it a very valuable thing?

Cord blood storage theoretically has no time limit and can be stored permanently.

There are many people who have certain doubts about self-stored cord blood, and a large part of the reason is that the storage time and quality of self-stored cord blood are concerned. Typically, cord blood is stored for 18 and 22 years. Many people will have such questions:

Umbilical cord blood that has been stored for more than ten years, if it is really needed one day, will it still have an effect? ”

In fact, there is no need to worry about the time and quality of self-stored cord blood, and the existing cell storage and technology can fully meet the storage requirements of cord blood. Moreover, although it is said to be self-stored umbilical cord blood, it is actually stored in the true sense of umbilical cord blood hematopoietic stem cells. The head of Life Bank explained.

Indeed, the latest modern preservation technology has made a particularly significant improvement over the previous preservation technology. Therefore, the preservation time of umbilical cord blood hematopoietic stem cells is relatively long, and theoretically, umbilical cord blood is said to be long-term cryopreservation, and there is no time limit. Practice has proved that the cell viability of a cord blood frozen for 40 years is particularly good.

It is necessary to preserve the cord blood. Umbilical cord blood can be a disease of the blood system in the body. We often hear about leukemia, for example, in the case of air pollution, fruit and vegetable pesticide pollution, the incidence of leukemia in China is also increasing year by year, and its incidence is concentrated in children aged 3-8 years old.

Therefore, storing umbilical cord blood is equivalent to buying a leukemia insurance for the child, so some people may ask, is it really reliable to use umbilical cord blood ** leukemia? For umbilical cord blood ** leukemia is not a Chinese characteristic, the earliest successful case of use for umbilical cord blood ** leukemia is in the United States, with the continuous progress of medical science and technology, now the use of umbilical cord blood ** leukemia has become a trend.

At present, the biggest obstacle to bone marrow transplantation is that the matching type is not suitable, and the human immune system can recognize whether this thing is a foreign substance or not by cell surface antigens. Bone marrow transplant patients are looking for the same type as antigens, which is very low, and if the bone marrow of several people is transplanted to the patient, the general patient will die.

The reason is that healthy people have immune cells in their bone marrow, and they will kill everything they encounter in the patient's body like a policeman, because they don't know it. This catastrophe is called the graft-versus-host response. The probability of being able to match is 1 4 among siblings and 1 400 among ordinary people, even those who find a match through the bone marrow bank.

More than 80 people also had graft-versus-host reactions of varying severity after surgery. So if you can keep a copy of your baby stem cells, when you're faced with something like this, you can give yourself your own match, which is a 100 match.

Let's consider whether it is worth it from another angle, when you are on the verge of death and cannot be saved, a chance to save suddenly appears, which can increase your survival probability by 1, how much are you willing to pay for this 1 100 chance? If you think that 100 million yuan buys this probability increase value, it is also worth it for you to keep umbilical cord blood.

It is necessary to preserve the umbilical cord blood, and the functions of umbilical cord blood are as follows:

Umbilical cord blood contains hematopoietic stem cells that can continue to differentiate and mature into functional cells under the right environment. Moreover, the content of umbilical cord blood stem cells is relatively large, you may have heard of bone marrow stem cells for bone marrow transplantation, and the content of umbilical cord blood stem cells is several times or even dozens of times higher than that of bone marrow stem cells. In addition, the degree of side effects such as rejection after cord blood stem cell transplantation is relatively small.

Therefore, the preservation of umbilical cord blood is mainly to preserve the stem cells in the umbilical cord blood, which can be used for hematologic diseases (such as leukemia), immune diseases, genetic diseases and certain tumors**.

Nowadays, when many people give birth in the hospital, there will be a staff member from the umbilical cord blood bank who will come to ask the mother if she wants to keep the umbilical cord blood. Many women have also heard that the preservation of cord blood can be used to treat diseases in the future. But there are also many people who do not keep cord blood.

If the donated cord blood stem cells are healthy stem cells, then other patients may benefit from cord blood stem cell transplantation. From this point of view, it is likely that the cord blood will be used by others in the future.

What are the pros and cons of cord blood retention:

Pros: The stem cells in umbilical cord blood can be used for some relatively rare diseases and are a valuable medical resource.

Disadvantages: Normally retained cord blood cannot be used on its own**; Expensive to save; Umbilical cord blood is not permanent and will become ineffective due to the gradual death of stem cells.

Nowadays, many mothers will choose to save a copy of cord blood for their baby, thinking that this is an extra insurance. So, is it necessary to preserve umbilical cord blood? Is it good or not? Today, I will learn some things about baby umbilical cord blood with you.

As a cell component in the early stage of the human body, umbilical cord blood stores the "life code" and "genetic information" of the early human body. Sun Yuan said, "If the child has some diseases, the cause of the child's disease can be understood through the research and testing of autologous umbilical cord blood. In addition, cord blood is easy to obtain, not only collected, but also has the characteristics of low contamination rate, wide range of applications, and low cost."

Umbilical cord blood preservation:

1.Umbilical cord blood is rich in a large number of hematopoietic stem cells, which can be used to replace bone marrow for stem cell transplantation. At present, there are more than 80 kinds of diseases that can be treated medically.

2.The probability of matching in the home bank is high, and there is no need for matching for autologous use. There is a 25% chance of full compatibility between siblings, and more than 50% of the places are compatible with parents.

3.If you choose to self-store your cord blood, pay the corresponding fees according to the regulations and keep it officially, you can get a free "comprehensive medical insurance" worth 550,000 yuan.

In fact, umbilical cord blood was never valued for a long time, but in recent years, umbilical cord blood has suddenly become a mess. Everyone has heard that umbilical cord blood will have a life-saving effect on their own children in the future. As a result, many parents choose to keep their child's cord blood for their child after birth.

But does cord blood really have that much effect? Is it necessary to save cord blood?

The annual cost of saving umbilical cord blood is an expensive amount, but because of the sentence "your own umbilical cord blood will never fail to match, saving your own umbilical cord blood is to protect your future health" makes many parents willing to spend a lot of money to preserve umbilical cord blood. But most of the requests to parents to preserve cord blood are propaganda from commercial organizations that exploit the fragile and great feelings of the parents before the child is born.

The amount of cord blood is very limited, and if it is used to treat children, such a small amount of blood can only meet the blood needs of childhood, which means that parents spend a lot of money to save umbilical cord blood can be useful for children when they are young. And another point is that if blood is needed for the disease of the inheritance, then umbilical cord blood should not be used at this time. Because cord blood can also carry genes for legacy diseases.

Therefore, I believe that everyone should have an answer to the question of whether it is necessary to preserve umbilical cord blood in combination with their own reality. If possible, you can choose to save your cord blood, but don't put your hopes for it.

What is cord blood? What is the role of umbilical cord blood?

According to your own situation! I've been depositing my cord blood for the second year and I've spent 17,100 yuan (16,000 yuan for the first time, 1,100 yuan per year thereafter)!

Just in case, I will keep it in the Beijing Umbilical Cord Blood Hematopoietic Stem Cell Bank, and you need to find a qualified umbilical cord blood bank to keep it.

Is it necessary to preserve umbilical cord blood is a question that parents will have every time a newborn is born, after all, there is only one such thing, and various wonderful uses of umbilical cord blood are circulating on the Internet, so the topic has become the focus. Let's take a look.

Vary.

Is it necessary to preserve umbilical cord blood is a question that many people have nowadays, as far as the experience of friends in the past, the preservation of umbilical cord blood is necessary, of course, the premise is that the economic conditions allow, after all, umbilical cord blood is the most suitable blood type for the fetus itself as a hail, once the fetus suffers from leukemia or aplastic anemia and other diseases that require hematopoietic stem cell transplantation, the matching and transplantation effect of umbilical cord blood must be the best.

Whether newborns need to store umbilical cord blood is often discussed, and the so-called umbilical cord blood is the blood that remains in the umbilical cord after the baby cuts the umbilical cord. It contains some hematopoietic stem cells that can be transplanted for a variety of diseases. For example, metabolic diseases, blood diseases, and immune diseases.

However, although the effect of umbilical cord blood is very large! However, after the autologous cord blood is preserved, it may not be used in the future. Because some blood diseases are chromosomal or genetic abnormalities, if your stem cells have a problem, they will not be used if they are preserved.

20 years. The storage period of umbilical cord blood is very large due to its particularity, and under normal circumstances, umbilical cord blood can be stored for 20 years. Umbilical cord blood is the blood that remains in the placenta and umbilical cord after the fetus is delivered and the umbilical cord is ligated and broken.

It can be said to be the initial source of blood in the human body. Modern medical research has shown that umbilical cord blood is very rich in hematopoietic stem cells, and when it comes to this hematopoietic stem cell, everyone feels more familiar, which is usually related to transplantation and blood diseases.

Umbilical cord blood is the blood of the fetus itself, but according to the previous data, the probability that the child can use his own umbilical cord blood is very low, and the data given by the American Blood and Marrow Transplant Association is. Moreover, many diseases are related to genetics, that is, the hematopoietic stem cells in umbilical cord blood are themselves problematic and cannot be used.

Umbilical cord blood is useful, but self-deposited cord blood is not necessary. According to experts, the original intention of retaining umbilical cord blood is to use hematopoietic stem cells with strong reproductive ability to transplant ants and exterminate patients with leukemia, aplastic anemia, lupus erythematosus and other diseases. However, the advantages of self-retained cord blood for these diseases are not clear.

First of all, the owners of the town's cord blood sellers have a relatively low chance of suffering from the above conditions, which directly leads to the fact that cord blood may never be used.

Secondly, even if a child has leukemia, he may not be able to use his or her umbilical cord blood. Because leukemia is also related to genetic factors, perhaps there is something wrong with his stem cells themselves. The same is true for other genetic disorders.

Finally, umbilical cord blood is preserved at birth, and there is no immune condition in it, and it has no effect against leukemia, and the effect is not good.

However, umbilical cord blood can still be useful, for example, if a patient with leukemia** has little hope of survival, if the sibling retains the cord blood and can match it, then the transplant will be very effective. Therefore, experts suggest that the umbilical cord blood can be donated to the public bank for those in need to use, avoiding limb and limb transfer, and the use rate is also greatly increased.

How to preserve umbilical cord blood.

After the cord blood is collected, it is temporarily stored in the environment of 4 24 and sent to the "Umbilical Cord Hematopoietic Stem Cell Bank" by the blood collection staff of the cord blood bank within 24 hours.

After the cord blood is sent to the cord blood bank, the staff will first check the maternal information in the blood collection room and establish a computer file for the cord blood. Then, the umbilical cord blood was sent to the ultra-clean room of the laboratory for the separation of umbilical cord blood hematopoietic stem cells, the test specimens were retained, cryoprotectants were added, and after testing, separation, preparation and other medical processes, they were frozen in -196 cryogenic liquid nitrogen for long-term storage. Each test result is reviewed by more than 2 people to ensure the accuracy of the test results and ensure the safety of the umbilical cord blood to the greatest extent.

The process and cost of self-deposited cord blood.

1.Pregnant women contact the local cord blood preservation machine before delivery.

2.Physical examination and evaluation at your own expense, and after passing the test, you can sign the "Umbilical Cord Blood Hematopoietic Stem Cell Storage Agreement".

3.After paying the corresponding fees, a set of cord blood collection related equipment will be obtained, which will be brought to the hospital at the time of delivery and handed over to the midwife.

4.Umbilical cord blood is collected by a medical staff at the time of delivery, and the doctor is asked to complete the cord blood collection form.

5.Notify the cord blood bank immediately after the cord blood is collected, and hand over the collected cord blood to a professional blood collector to transport the cord blood to the cord blood bank within 24 hours.
