Umbilical cord stem cells.

Clinics sell donor cells grown from umbilical cord tissue, ready-frozen with no harvest from your body. In the US, the only approved cord product is cord blood for rebuilding blood and immune systems. Cord tissue cells are not approved anywhere this site covers.[1][2]

Three different products share the name

Cord blood stem cells

Blood-forming cells from cord blood, used to rebuild a patient's blood and immune system. This is the only approved use in the US, with nine licensed products.[1][3]

Cord tissue or Wharton's jelly cells

Mesenchymal cells grown from the cord's connective tissue. This is what most private clinics inject, and it is not approved in any market this site covers.[2][1] About mesenchymal stem cells

Other cord blood cells

Cells grown or separated from cord blood for other uses, mostly in research.[4][5]

How it is given

The product arrives frozen from a donor, is thawed and is injected into a joint or given by drip. There is no harvest from your body.[6] Patients describe a needle-only or drip-only day, and repeat rounds are common.[7]

No tissue matching is done for cord cells sold as a treatment: they are given off the shelf, without matching and without anti-rejection drugs.[8]

No better than the patient's own cells, or a steroid

Side effects

Fever is about twice as common as with control.[11] In knee trials, short-lived reactions such as swelling were far more common with donor cord cells than with your own fat cells.[12] Donor cells can trigger antibodies: 5 of 12 children given a cord tissue product made new antibodies, which can make a future organ transplant harder to match.[13] In 2018, contaminated cord products put 12 US patients in hospital with blood and joint infections.[14]

Common questions

Is this the same as the cord blood we banked at birth?

Only if the cord blood is used for a blood or immune disorder.[1][3] The American Academy of Pediatrics notes private banking is expensive, not covered by insurance, and the unit may never be used.[20]

Are donor cord cells better because they are younger?

They grow faster in a dish, but no trial has shown a benefit in patients.[21][6]

Does freezing matter?

Yes. Thawed cells release fewer anti-inflammatory signals and are cleared faster.[22]

Questions to ask a clinic

  1. Is this cord blood, or cells grown from cord tissue?
  2. Can I see the certificate of analysis for my batch before I pay?
  3. How many live cells are in the vial, and how was that measured?
  4. How was the donor screened?
  5. Was it frozen, and how long ago?
  6. Could repeat doses affect a future transplant?
