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 consequence broke open an entire new subject 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.

Today, in actual fact, being pregnant means being bombarded on the physician’s workplace and on Instagram with advertisements touting wire blood as too valuable to waste. For a number of hundred {dollars} upfront, plus a storage payment of $100 to $200 yearly, the banks’ advertisements proclaim, you could possibly 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 wire blood banks are Twine Blood Registry and ViaCord. Collectively, they’ve collected greater than 1 million models. However only some hundred models of this privately banked wire 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 wire 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 companies for households by which somebody has already been recognized with a situation treatable with wire blood. Basically, the businesses reiterated to me, wire blood does save lives and they’re merely offering an choice for households who need it.

However the advertising and marketing additionally gives the look of far more expansive makes use of for wire blood. The non-public banks’ web sites listing almost 80 ailments treatable with transplantation—a formidable 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 wire blood, they are saying, might ultimately deal with extra frequent circumstances reminiscent of cerebral palsy and autism. Video testimonials function mother and father speaking excitedly in regards to the potential of wire blood for his or her youngsters. However the proof isn’t there but—and should by no means seem. Nonetheless, says Paul Knoepfler, a stem-cell scientist at UC Davis, “the cord-blood corporations appear to be attempting to develop their base of potential clients.”


The preliminary exuberance round wire 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 purple 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 wire 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 permits medical doctors to make use of wire blood that matches solely 4 out of six immunological markers.

As a result of wire blood is so priceless, publicly run banks have been amassing donations because the Nineteen Nineties. Regardless of amassing fewer models total, 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 suggest donating to public banks.

One attraction of personal banking, although, as the businesses spotlight, is that the cells in a child’s umbilical wire are an ideal match for them in later childhood or maturity. However that is often irrelevant: In a lot of the ailments that may be cured by a cord-blood transplant, medical doctors would, for medical causes, not use the affected person’s personal cells. In circumstances of inherited issues reminiscent of sickle cell anemia, for instance, a toddler’s personal cord-blood stems have the identical problematic mutation. For kids with one in all many forms of leukemia, the priority is that wire blood might comprise 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 wire blood from a toddler with a lot of 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 wire blood is utilized in transplants, it’s extra more likely to go to a sibling. Genetically, siblings have a couple of 25 p.c probability of being excellent matches for one another. The probabilities of discovering an acceptable match amongst unrelated bone-marrow or cord-blood donors from a public financial institution, however, vary from 29 to 79 p.c, relying on one’s ethnic background. (Nearly all of donors are white, so it’s highest for white sufferers.) In any case, not banking a matched sibling’s wire blood doesn’t foreclose the opportunity of 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 wire blood, and I’ll level out, ‘Effectively, your donor little one that matches our affected person remains to be right here,’” says Ann Haight, a pediatric hematologist and oncologist at Emory College.

Even when a child’s wire blood is banked, there’s no assure that it’s going to comprise sufficient cells for a transplant. The truth is, most might not: Public banks solely maintain 5 to 40 p.c of their donations, as the remainder don’t meet their requirements. Personal banks will save a lot smaller samples, which they argue serve a special objective. Whereas public banks are on the lookout for massive samples which can be principally possible 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 wire, so our threshold is means 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 reminiscent of cerebral palsy and autism. (About 80 p.c of models launched by CBR have been used this manner, as have about half from ViaCord.) The non-public banks associate with researchers, reminiscent of Kurtzberg at Duke, who’re operating medical trials to check these therapies. The idea goes that cells from wire blood could make it to the mind, the place they could have some neuroprotective position—however the mechanism stays unknown, and the consequences will not be completely clear. As Kurtzberg informed me, “The remedy shouldn’t be confirmed.”

The present state of cord-blood science is perhaps summed up thus: Confirmed makes use of are very unusual, and unproven makes use of are, effectively, unproven. In fact, a future discovery might result in an actual breakthrough in the usage of stem cells from wire blood—an concept non-public banks commerce on. Who is aware of what is perhaps in retailer for wire 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 informed me by e-mail, 45 p.c named “perception in future therapies” as the first cause for banking their little one’s wire 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 attention-grabbing ends in the lab to a physician’s workplace, he says, “​​is de facto a lot tougher than many people realized. I embrace myself in that.”

Medical discoveries have really modified the methods wire blood is used over years, however they’ve thus far resulted in much less use of wire blood. Up to now a number of years, medical doctors 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 wire blood, which implies the transplants “take” extra rapidly and the affected person spends much less time within the hospital. Because of this, wire blood has been falling out of favor. Public banks have began cutting down their collections; the New York Blood Heart, which had launched the world’s first public financial institution, just lately stopped amassing new donations. How wire blood will get used sooner or later remains to be unknown.


Greater than 30 years in the past after Kurtzberg first handled Farrow, she remains to be in contact with him. He’s 39 now, and doing effectively. Having watched wire banking develop and evolve through the years, she stays a proponent of public banking and the chances forward. In terms of non-public banks, nevertheless, she says, “I don’t suppose it is a necessity. I feel 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 perhaps the important thing phrase right here. The advertisements for cord-blood banking really feel rather a lot 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 larger than the rest you may select to purchase. The chance solely comes round “as soon as in a lifetime,” and it might actually save your little one’s life—even when the probabilities of which can be very, very small. “It’s enjoying to parental guilt and the need for folks to have wholesome youngsters and do no matter they will for his or her youngsters,” says Timothy Caulfield, a health-law professor on the College of Alberta who has studied cord-blood banks. “There’s an enormous market based mostly on precisely that.”

It’s telling, maybe, that Twine Blood Registry ran a giveaway of $20,000 value of child merchandise this summer season. The curated bundle of luxurious “child necessities” resembled the registry of fogeys who need the perfect for his or her child, and might afford it. Included had been a Snoo good bassinet ($1,695), an Uppababy stroller and automotive 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).
