摘自wikipedia的一些负面评论Legality and ethics
In the United States, cord blood education is supported by legislators at the federal and state levels. In response to their constituents, state legislators across the United States are introducing legislation intended to help inform physicians and expectant parents on the options for donating, discarding, or banking lifesaving newborn stem cells. Currently, 17 states, covering two-thirds of U.S. births, have enacted legislation recommended by the IoM guidelines.[citation needed]
In 2004, the European Group on Ethics in Science and New Technologies advised the European Commission that "The legitimacy of commercial cord blood banks for autologous [self] use should be questioned as they sell a service, which has presently, no real use regarding therapeutic options. Thus, they promise more than they can deliver. The activities of such banks raise serious ethical criticisms."[32] For those at low risk, private storage of one's own cord blood is unlawful in Italy and France, and discouraged in some other European states.[1][33]
Some doctors and patients have stated that the claims of some private cord blood banks are deceptive and misleading.[33][34][35]
[edit] Controversy among medical societies
The Royal College of Obstetricians and Gynaecologists 2006 opinion states, "There is still insufficient evidence to recommend directed commercial cord blood collection and stem-cell storage in low-risk families."[1]
The policy of the Society of Obstetricians and Gynaecologists of Canada (SOGC) supports public cord blood banking (similar to collection and banking of other blood products, i.e. altruistic, anyone can use it), as well as stating it should be considered under certain circumstances. SOGC Clinical Practice Guidelines, No. 156, March 2005.[36] Umbilical Cord Blood Banking: Implications for Perinatal Care Providers
The policy of the American Academy of Pediatrics policy states that "private storage of cord blood as 'biological insurance' is unwise" unless there is a family member with a current or potential need to undergo a stem cell transplantation.[2]
Similarly, the American College of Obstetricians and Gynecologists does not recommend private cord blood banking.
Private storage of one's own cord blood is unlawful in Italy and France, and it is discouraged in some other European states.[1][2][3] the American Academy of Pediatrics states that private cord blood banking is generally not recommended unless there is a family history of specific genetic diseases.[33]
The American Society for Blood and Marrow Transplantation[37] states that public donation of cord blood is encouraged where possible, the probability of using one's own cord blood is very small, and therefore storage of cord blood for personal use is not recommended, and family member banking (collecting and storing cord blood for a family member) is recommended when there is a sibling with a disease that may be treated successfully with allogeneic transplant.
[edit] Safety and effectiveness of using one's own cells unclear
Using one's own cord blood cells might not be wise or effective, especially in cases of childhood cancers and leukemia.[38] Children who develop an immunological disorder often are unable to use their own cord blood for transplant because the blood also contains the same genetic defect. Nearly all of the transplants using privately banked cord blood have gone to relatives with pre-existing conditions, not to the donors.[33]
Additional issues include the possible contamination of the cord blood unit with the same cancer diagnosed later in life; for example, abnormal cells have been detected in filters containing newborn blood of children who were not diagnosed with acute leukemia until the age of 2 to 6 years. The high relapse rates after autologous or syngeneic tranplant and the benefit of a graft-vs.-leukemia effect of an allogeneic transplant suggest that autologous cord blood would not be the ideal source of stem cells for patients with leukemia needing a transplant.[39]
[edit] Usability of one's own sample unknown
Most cord blood samples - up to 75% - may be too small to be used for transplantation because they don't contain enough stem cells.[33] While a private bank will store a sample, the sample may be too small to be usable, even by a child. Larger numbers of blood cells are required for adults because of their typically larger body mass.
[edit] Ownership of cord blood
As of 2007, contracts of the largest cord blood banks do not explicitly state that the cord blood belongs to the donors and child with all the rights and privileges one would reasonably expect from ownership. The ambiguity leaves open future uses not approved by the donors and child. Some contracts fail to spell out the rights of the donors requesting termination of storage: e.g. the right to request and verify destruction of the samples (as when a period of likely need has passed, or their minds have changed).[citation needed]
[edit] Medical issues
Concerns have been raised that the current interest in cord blood could cause a perception that cord blood is 'unused' by the birth process, thus decreasing the amount of blood which is infused into the child as part of the birth process. The pulsation of the cord pushes blood into the child, and it has been recommended that the cord cease pulsation prior to clamping. With the demand for cord blood increasing, there is a possibility that the cord could be clamped prematurely to preserve even more 'extra' cord blood. This action could have detrimental effects on the child's future development.[40]
The American Academy of Pediatricians notes: "if cord clamping is done too soon after birth, the infant may be deprived of a placental blood transfusion, resulting in lower blood volume and increased risk for anemia."[2]
The Journal of the American Academy of Pediatrics published an article in April 2006 recommending that clamping be delayed to reduce anemia and improve neonatal iron storage.[41][niumum (1-16 15:18, Long long ago)]

(引用 niumum:摘自wikipedia的一些负面评论Legality and ethics
In the United States, cord blood education is supported by legislators at the fe...)American Academy of Pediatrics的评价That American Academy of Pediatrics sums up most of the cons against private cord banking nicely in their subject review of cord blood banking, in which they state that 'Families may be vulnerable to emotional marketing at the time of birth of a child and may look to their physicians for advice. No accurate estimates exist of the likelihood of children to need their own stored cells. The range of available estimates is from 1:1000 to 1:200,000. Empirical evidence that children will need their own cord blood for future use is lacking. There also is no evidence of the safety or effectiveness of autologous cord blood transplantation for the treatment of malignant neoplasms. For these reasons, it is difficult to recommend that parents store their children's cord blood for future use.'
Also keep in mind that the AAP again, in a 2007 policy statement on cord blood banking titled Cord Blood Banking for Potential Future Transplantation, stated that 'private storage of cord blood as "biological insurance" should be discouraged.'
Also, if your child does get one of the conditions that an umbilical cord transplant is supposed to cure or treat, if you don't store your child's cord blood, that doesn't mean that no treatments will be available to him. In addition to more traditional treatments and bone marrow transplants, you may be able to find a cord blood match in a public cord blood bank, from which most cord blood transplants are currently being done.[niumum (1-16 15:47, Long long ago)]

(引用 bbsg2005:babycenter有一个详尽的优缺点的list，孕期读了就没打算给宝宝存。)Private cord blood banking: Is it for you?http://www.babycenter.com/0_private-cord-blood-banking-is-it-for-you_1369773.bc
What do I need to know about private cord blood storage?
It sounds like a great idea – a new form of medical insurance for your family. But private cord blood banking has sparked fierce debate in the scientific and medical communities.
The cost of private cord blood banking is high. And at this point the chances that your family will need to rely on the blood you've banked are low, unless a disease that can be treated with cord blood runs in your family. On the other hand, advances are being made all the time, and for that reason, advocates say, banking cord blood is a good investment.
According to a study at the University of California, San Francisco, the chances of privately stored umbilical cord blood being therapeutic for a child or immediate family member in the next 20 years probably don't justify the expense of private storage. Researchers estimated the chances at 1 in 2,500 per individual.
"While there are plausible medical advantages of umbilical cord blood stem cells, many of these benefits are primarily theoretical at this point," says Anjali Kaimal, an ob-gyn at Massachusetts General Hospital in Boston and the study's lead researcher. "Expectant parents need to understand the true likelihood of their family benefiting from private cord blood banking in order to make an informed decision about this expensive process."
Only you can decide whether private cord blood banking is right for your family. Here are some things to consider when making your decision:
In most cases, it's better not to treat a child with his own cord blood.
In the case of many childhood cancers and immune deficiencies, a child would not be given his own cord blood. Those stem cells would probably carry the disease genetically, meaning that you'd be reintroducing those defective cells into the child.
In these instances, the best transplant donor would be a matching sibling. (The chance of two siblings being a good match is 25 percent.) For some diseases without a genetic basis, though, a patient's own cells are the best bet because his body won't react against them or reject them.
Researchers hope that cord blood will eventually be used to treat people of all ages with a wide variety of conditions, including diabetes, spinal cord injuries, heart failure, stroke, and neurological disorders like multiple sclerosis. At this point the studies are preliminary but promising.
Your baby's cord blood might not have enough stem cells to treat you or other adults in your family.
One unit of cord blood typically doesn't contain enough stem cells to treat most adults.
According to William Shearer, a professor of pediatrics and immunology at Baylor College of Medicine in Houston and coauthor of the 2007 American Academy of Pediatrics statement on cord blood transplants, researchers have not been able to routinely expand the number of stem cells in a unit of cord blood. But there have been successful transplants involving a combination of two or three cord blood units from unrelated donors – another way of stretching this scarce resource.
Most people have a better chance of finding a stem cell match in the public cord blood system than in their own family.
The chance of an exact tissue match between two siblings is 25 percent, according to Dennis Confer, a hematologist and internist and the chief medical officer for the National Marrow Donor Program (NMDP), a nonprofit organization that facilitates unrelated cord blood and marrow transplants. By contrast, the chance of finding a cord blood match in the nation's public banks is 95 percent, and possibly higher if international databases are searched, he says.
Cord blood isn't the only source of stem cells.
Stem cells are found in circulating blood (also called peripheral blood), bone marrow, hair follicles, fat, baby teeth, and muscle. They're also found in human embryos and fetal tissue, but the use of those cells is controversial. Bone marrow, peripheral blood, and cord blood are the only sources of stem cells currently used for transplants.
Studies show that stem cells from cord blood have certain advantages over other sources of stem cells, but they're not yet the clear winner. "Today, the most common source of stem cells is peripheral blood stem cells," says Mary Halet, director of recruitment and community development at the NMDP. "We're finding about an equal split between bone marrow and cord blood [for other transplants]."
Learn more about the advantages and disadvantages of cord blood and bone marrow.
Unless you select your private bank carefully, the cord blood you bank privately may not be suitable for transplants.
If the day comes when one of your children needs the cord blood you've stored privately, your child's doctor may reject it. The practices and standards of private banks vary, and your sample may not contain enough stem cells for a successful transplant. It's crucial, if you decide to store cord blood privately, that you choose a private cord blood bank carefully.
You may be able to get donated cord blood back.
If you donate your cord blood to a public bank, it's available for the public and any potential matching patient, as well as for research. That means that there's no guarantee that you'll be able to access it if you need it for your family later. But if the need does arise and your donation is still available, you'd have access to it just as anyone else would.
"If the cord blood you donated to a public bank is the optimal one for a transplant for you, it will be available to you unless it has already been used by another person," says Lawrence D. Petz, chief medical officer of StemCyte, a cord blood bank with both a public and a private division. "The likelihood of it having been used is low, since less than 10 percent of publicly banked units are used."

Cord blood research is showing promising results.
Studies are under way around the world, and many researchers are optimistic about the future of cord blood. Researchers believe that adult cancer patients may one day benefit from treatment with their own cord blood stem cells that were harvested at birth. The hope is that stem cells will be useful for treating cancers that aren't genetically based.
In light of recent animal experiments, many researchers also believe that cord blood may eventually be used to treat people with conditions as varied as diabetes, spinal cord injuries, heart failure, stroke, and neurological disorders such as multiple sclerosis.
Scientists at the University of South Florida's Center of Excellence for Aging and Brain Repair found that cord blood stem cells helped rats with stroke or spinal cord injuries recover some motor function and helped mice programmed to develop Lou Gehrig's disease develop symptoms more slowly and survive longer. The center is looking at cord blood treatments for diseases like Alzheimer's and Parkinson's as well.
Many experts urge parents to view such studies (especially those conducted on animals) cautiously. It's difficult to predict when, if ever, these treatments will become available for humans.
"Most of these studies have been performed on animals, but the preliminary results have been very encouraging," says Paul Sanberg, executive director of the Center of Excellence for Aging and Brain Repair and vice-chair of the department of neurosurgery and brain repair at the University of South Florida.
Even if you have a family history of certain diseases, public banks may be able to meet your needs.
If your family has a history of leukemia, lymphomas, sickle cell anemia, immune deficiency diseases, aplastic anemia, thalassemia, or other similar conditions, your family's odds of needing a stem cell transplant are higher than the general population's. If you have or plan to have more than one child, you may find the idea of private cord blood storage reassuring.
On the other hand, publicly donated cord blood increases access to transplants. The NMDP says that with cord blood included in its Be the Match Registry, the chances are good that everyone will find a match – with either a cord blood unit or an adult donor.
For help assessing your risk of having a child with one of these diseases, ask your healthcare provider for a referral to a genetic counselor.
If you decide on private storage and you plan to have more than one child, consider banking each child's cord blood.
The more cord blood units you have in storage, the more likely it is that you'll find a perfect match for one of your children. Again, with each sibling there's a 25 percent chance that the stem cells will be a match, and the odds increase significantly with each additional sibling.
If you decide that private cord blood banking is for you, find out how to choose a private cord blood bank. Be sure the doctor or midwife who will deliver your baby is aware of your decision and knows how to harvest cord blood.
