Is Cord-Blood Banking Worth It?

Up to date at 3:30 p.m. ET on October 17, 2022

Within the fall of 1988, Matthew Farrow, a 5-year-old boy with a uncommon blood dysfunction, acquired the world’s first transplant of umbilical-cord blood from a new child sibling. It labored: Farrow was cured. This miraculous end result broke open an entire new area in drugs—and, not lengthy after, an entire new business geared toward getting anticipating mother and father to financial institution their child’s umbilical-cord blood, simply in case.

As of late, the truth is, being pregnant means being bombarded on the physician’s workplace and on Instagram with advertisements touting twine blood as too treasured to waste. For a number of hundred {dollars} upfront, plus a storage payment of $100 to $200 yearly, the banks’ advertisements proclaim, you might save your little one’s life. Twine-blood banking has been likened to a “organic insurance coverage coverage.”

Within the U.S., the 2 largest non-public twine blood banks are Twine Blood Registry and ViaCord. Collectively, they’ve collected greater than 1 million models. However just a few hundred models of this privately banked twine blood have ever been utilized in transplants, the nice majority by households who selected to financial institution as a result of they already had a toddler with a particular and uncommon dysfunction treatable with a transplant. For everybody else, the percentages of utilizing privately banked twine blood are minuscule—so minuscule that the American Academy of Pediatrics (AAP) recommends in opposition to non-public banking. It does make an exception for households with that illness historical past. “However that’s a uncommon circumstance,” says Steve Joffe, a pediatric oncologist and ethicist on the College of Pennsylvania, “and never one which anyone goes to construct a profitable enterprise mannequin round.”

ViaCord and Twine Blood Registry do provide free providers for households wherein somebody has already been identified with a situation treatable with twine blood. Normally, the businesses reiterated to me, twine blood does save lives and they’re merely offering an possibility for households who need it.

However the advertising additionally gives the look of rather more expansive makes use of for twine blood. The non-public banks’ web sites listing practically 80 illnesses treatable with transplantation—a powerful quantity, although many are extraordinarily unusual or intently associated to 1 one other. (For instance: refractory anemia, refractory anemia with ringed sideroblasts, refractory anemia with extra blasts, refractory anemia with extra blasts in transformation.) They’ve additionally just lately taken to highlighting the promise of still-unproven therapies: Non permanent infusions of twine blood, they are saying, may finally deal with extra frequent circumstances comparable to cerebral palsy and autism. Video testimonials function mother and father speaking excitedly in regards to the potential of twine blood for his or her youngsters. However the proof isn’t there but—and will by no means seem. Nonetheless, says Paul Knoepfler, a stem-cell scientist at UC Davis, “the cord-blood corporations appear to be making an attempt to broaden their base of potential prospects.”


The preliminary exuberance round twine blood got here from an actual place. The blood left over in umbilical cords is replete with cells which have the particular means to show into any sort of blood, together with crimson blood cells, which carry oxygen, and white blood cells, which make up the immune system. Adults have stem cells of their bone marrow and blood—which may also be used for a transplant—however these in a child’s umbilical twine are extra immunologically naive. Which means they’re much less more likely to go awry and assault a recipient’s physique. “They don’t trigger as a lot havoc,” says Karen Ballen, an oncologist on the College of Virginia. This enables docs to make use of twine blood that matches solely 4 out of six immunological markers.

As a result of twine blood is so beneficial, publicly run banks have been accumulating donations for the reason that Nineteen Nineties. Regardless of amassing fewer models general, public banks worldwide have offered 30 occasions as many models of blood for therapy—and saved extra lives—than non-public ones, as a result of they’re accessible by any affected person in want. Though the AAP recommends in opposition to non-public banking, it does advocate donating to public banks.

One attraction of personal banking, although, as the businesses spotlight, is that the cells in a child’s umbilical twine are an ideal match for them in later childhood or maturity. However that is often irrelevant: In a lot of the illnesses that may be cured by a cord-blood transplant, docs would, for medical causes, not use the affected person’s personal cells. In circumstances of inherited issues comparable to sickle cell anemia, for instance, a toddler’s personal cord-blood stems have the identical problematic mutation. For kids with certainly one of many varieties of leukemia, the priority is that twine blood may include leukemia-precursor cells that trigger the most cancers to reappear; as well as, donor blood-stem cells are higher as a result of they will mop up remaining leukemia cells. Medical doctors would “by no means” use banked twine blood from a toddler with all these leukemia, says Joanne Kurtzberg, a pediatrician and cord-blood pioneer at Duke College, who helped deal with Farrow when he was a younger boy.

When privately banked twine blood is utilized in transplants, it’s extra more likely to go to a sibling. Genetically, siblings have a couple of 25 % likelihood of being good matches for one another. The possibilities of discovering an acceptable match amongst unrelated bone-marrow or cord-blood donors from a public financial institution, then again, vary from 29 to 79 %, relying on one’s ethnic background. (The vast majority of donors are white, so it’s highest for white sufferers.) In any case, not banking a matched sibling’s twine blood doesn’t foreclose the potential for a transplant, as a result of that sibling can nonetheless donate bone marrow. “I usually encounter households who’ve some guilt round not storing the twine blood, and I’ll level out, ‘Nicely, your donor little one that matches our affected person continues to be right here,’” says Ann Haight, a pediatric hematologist and oncologist at Emory College.

Even when a child’s twine blood is banked, there’s no assure that it’s going to include sufficient cells for a transplant. The truth is, most might not: Public banks solely hold 5 to 40 % of their donations, as the remaining don’t meet their requirements. Personal banks will save a lot smaller samples, which they argue serve a distinct function. Whereas public banks are in search of giant samples which might be largely doubtless for use for transplants, says Kate Girard, the director of medical and scientific affairs at ViaCord, “when households are banking with us, that is that little one’s solely twine, so our threshold is manner decrease.”

Another excuse to financial institution these smaller samples, a spokesperson for Twine Blood Registry identified, is that they will nonetheless be used for experimental infusions treating circumstances comparable to cerebral palsy and autism. (About 80 % of models launched by CBR have been used this manner, as have about half from ViaCord.) The non-public banks accomplice with researchers, comparable to Kurtzberg at Duke, who’re working medical trials to check these therapies. The idea goes that cells from twine blood could make it to the mind, the place they could have some neuroprotective function—however the mechanism stays unknown, and the consequences are usually not fully clear. As Kurtzberg advised me, “The remedy is just not confirmed.”

The present state of cord-blood science is likely to be summed up thus: Confirmed makes use of are very unusual, and unproven makes use of are, effectively, unproven. After all, a future discovery may result in an actual breakthrough in the usage of stem cells from twine blood—an thought non-public banks commerce on. Who is aware of what is likely to be in retailer for twine blood later, when your child is 30, 50, 70 years previous? In a latest Twine Blood Registry survey of latest mother and father, a spokesperson advised me by e-mail, 45 % named “perception in future therapies” as the first purpose for banking their little one’s twine blood and tissue. Knoepfler, the stem-cell scientist, notes that scientists have been excited for many years in regards to the promise of stem cells. However translating fascinating leads to the lab to a health care provider’s workplace, he says, “​​is basically a lot tougher than many people realized. I embrace myself in that.”

Medical discoveries have truly modified the methods twine blood is used over years, however they’ve up to now resulted in much less use of twine blood. Prior to now a number of years, docs have refined a protocol to make use of half-matched donors in transplants. Medical doctors typically get extra cells from these donors than from an toddler’s banked twine blood, which suggests the transplants “take” extra shortly and the affected person spends much less time within the hospital. Because of this, twine blood has been falling out of favor. Public banks have began cutting down their collections; the New York Blood Middle, which had launched the world’s first public financial institution, just lately stopped accumulating new donations. How twine blood will get used sooner or later continues to be unknown.


Greater than 30 years in the past after Kurtzberg first handled Farrow, she continues to be in contact with him. He’s 39 now, and doing effectively. Having watched twine banking develop and evolve over time, she stays a proponent of public banking and the probabilities forward. In the case of non-public banks, nonetheless, she says, “I don’t suppose it is a necessity. I believe it’s good to have if you are able to do it.” There isn’t a lot hurt in non-public banking, in any case, so long as mother and father can afford the a number of thousand {dollars} over their little one’s lifetime.

Afford is likely to be the important thing phrase right here. The advertisements for cord-blood banking really feel loads like these for any variety of “good to have” child merchandise geared toward anxious mother and father, be they natural diapers or BPA-free wood toys tailor-made to your little one’s age and cognitive improvement. If something, the stakes of cord-blood banking are increased than the rest you would possibly select to purchase. The chance solely comes round “as soon as in a lifetime,” and it may actually save your little one’s life—even when the possibilities of which might be very, very small. “It’s taking part in to parental guilt and the need for fogeys to have wholesome youngsters and do no matter they will for his or her children,” says Timothy Caulfield, a health-law professor on the College of Alberta who has studied cord-blood banks. “There’s an enormous market primarily based on precisely that.”

It’s telling, maybe, that Twine Blood Registry ran a giveaway of $20,000 price of child merchandise this summer time. The curated package deal of luxurious “child necessities” resembled the registry of fogeys who need one of the best for his or her child, and might afford it. Included had been a Snoo sensible bassinet ($1,695), an Uppababy stroller and automobile seat ($1,400), Coterie diapers ($100 for a month’s provide, assured to be “freed from perfume, lotion, latex, rubber, dyes, alcohol, heavy metals, parabens, phthalates, chlorine bleaching, VOCs, and optical brighteners”), and, after all, a lifetime of cord-blood and tissue banking ($11,860).
