*Written by [Oscar Tellez](https://regenmedacademy.com/oscar-tellez/), founder of Regen Med Academy. Oscar is not a clinician. This post is education for licensed providers and is not medical advice. Last updated October 28, 2026.*

Wharton’s jelly is the gelatinous connective tissue inside the umbilical cord, where it surrounds the cord’s blood vessels. When a rep uses the term in your office, it means a donor product that a company makes from a donated cord. It is not the patient’s own tissue, and no Wharton’s jelly product is FDA approved. This post explains what Wharton’s jelly is, how donor tissue is screened, and which terms get mixed up with it.

## What is Wharton’s jelly, and where does it come from?

Start with the cord itself. StatPearls is a medical reference that the National Library of Medicine hosts on its Bookshelf site. Its anatomy chapter says “[the umbilical cord consists of a bundle of blood vessels enclosed within a tubular sheath of amnion](https://www.ncbi.nlm.nih.gov/sites/books/NBK557389/).” Amnion is the membrane that forms the cord’s outer cover.

The same chapter counts the vessels for you. It says, “The structure typically contains 2 umbilical arteries and 1 umbilical vein.”

So what fills the space between those three vessels and the cover? That is Wharton’s jelly. The chapter calls it “a gelatinous connective tissue known as the Wharton jelly,” and says it is “composed primarily of mucopolysaccharides.” In plain words, it is a soft gel made mostly of long sugar molecules.

How much of the cord is jelly? Most of it is. The chapter says, “The bulk of the umbilical cord is composed of the Wharton jelly.” It also says this gel “encases the umbilical vessels.”

All of that is anatomy. It describes where this tissue sits inside the cord before a baby is born. It says nothing about what a product does in a patient, and neither does this post.

## Is Wharton’s jelly the patient’s own tissue?

No, it is not. Wharton’s jelly comes from a donor, and the federal tissue rules define that word. [21 CFR 1271.3](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-A/section-1271.3) says a donor is “a person, living or dead, who is the source of cells or tissue for an HCT/P.” HCT/P is the rule’s short name for a human cell or tissue product.

The next word to know is autologous. The same rule defines autologous use as putting cells or tissue “back into the individual from whom the cells or tissue were recovered.” PRP is the everyday example, because the blood is drawn from a patient and goes back to that same patient.

The word after that is allogeneic, and it simply means the material comes from another person. Wharton’s jelly is allogeneic. The cord came from one birth, and the product is meant for someone who was not part of that birth.

Why does that matter to you? It matters because you did not make the product. A company collected the cord, screened the donor, processed the tissue and shipped a vial. So most of what you need to know sits in that company’s records.

FDA’s patient page covers both kinds of source. It says its list of unapproved products applies “[whether recovered from your own body or another person’s body](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/important-patient-and-consumer-information-about-regenerative-medicine-therapies).” So a donor source does not put a product outside FDA’s rules, and the patient’s own body does not either.

## How is a donor screened and tested?

The rules are in 21 CFR Part 1271, and the part on donors is [Subpart C, Donor Eligibility](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-C). The rule says a “donor-eligibility determination” is “required for all donors of cells or tissue used in HCT/Ps,” with a short list of exceptions. That decision has to be “based on donor screening and testing for relevant communicable disease agents and diseases.”

In plain words, someone has to decide on the record that the donor is eligible. The next paragraph says a product “must not be implanted, transplanted, infused, or transferred until the donor has been determined to be eligible,” again with listed exceptions.

So the decision has two parts. Screening is a review of records, and the rule says the firm screens a donor “by reviewing the donor’s relevant medical records.” The review looks for risk factors and signs of the listed diseases, which include HIV, hepatitis B and hepatitis C.

Testing is lab work on a specimen. [Section 1271.85](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-C/section-1271.85) lists what every donor must be tested for. The list is HIV type 1 and type 2, hepatitis B, hepatitis C, and Treponema pallidum, the agent that causes syphilis. The section adds more tests for donors of what it calls “viable, leukocyte-rich cells or tissue,” so ask the vendor which paragraph its donors were tested under.

Birth tissue has its own line in the rule. [Section 1271.80](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-C/section-1271.80) says, “In the case of a donor 1 month of age or younger, you must test a specimen from the birth mother instead of a specimen from the donor.” So with a cord from a newborn, the specimen that gets tested comes from the mother.

The same section covers the tests and the lab. The tests must be “FDA-licensed, approved, or cleared donor screening tests.” The lab that runs them has to meet the federal lab law known as CLIA, or an equal standard.

When is a donor eligible? The rule says screening has to show the donor “Is free from risk factors for, and clinical evidence of, infection” from the listed diseases. The donor’s tests also have to be “negative or nonreactive,” with one listed exception.

One caution before you lean on any of this. These donor rules exist to keep disease from spreading. They do not review what a product is claimed to do, and meeting them is not an FDA approval.

## How is donor tissue processed?

Every company has its own process, so this section is an outline and not a recipe. The rule gives you the words to use. Its word for the collecting step is “recovery.” It defines that step as “obtaining from a human donor cells or tissues that are intended for use in human implantation, transplantation, infusion, or transfer.”

Processing is nearly everything after that. The rule defines it as “any activity performed on an HCT/P, other than recovery, donor screening, donor testing, storage, labeling, packaging, or distribution.” Its examples include “testing for microorganisms, preparation, sterilization,” and “preservation for storage.”

So here is the path in outline. A cord is collected at a birth, the donor is screened and tested, and the tissue is processed. Then the product is labeled, stored and shipped.

A set of rules called current good tissue practice covers that whole path. [Section 1271.150](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-D/section-1271.150) says firms must follow them “to prevent the introduction, transmission, or spread of communicable diseases by HCT/Ps.”

One processing rule is easy to check, and it is about pooling. [Section 1271.220](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-L/part-1271/subpart-D/section-1271.220) says, “Human cells or tissue from two or more donors must not be pooled (placed in physical contact or mixed in a single receptacle) during manufacturing.” So ask whether each lot comes from one donor.

What the rule does not tell you is how one company turns a cord into the contents of a vial. Was the tissue cut, ground or filtered? Was it frozen, and was anything added to it?

Those answers belong to the maker, and they matter. FDA’s consumer page says, “[Those HCT/Ps that pose an additional risk because of their processing or use also require FDA approval before marketing](https://www.fda.gov/consumers/consumer-updates/it-really-fda-approved).” So processing is part of how FDA sorts a product, and that question has its own post later in this series.

## What paperwork comes with a donor product?

The rule answers this one in a list. Once the eligibility decision is made, section 1271.55 in that same subpart says three things “must accompany the HCT/P at all times.”

1. “A distinct identification code affixed to the HCT/P container.” The code ties the product to its donor and to every record about it.
1. “A statement whether, based on the results of screening and testing, the donor has been determined to be eligible or ineligible.”
1. “A summary of the records used to make the donor-eligibility determination.”

What goes in that summary? It has to say that the disease tests were run by a lab that meets the CLIA standard, or an equal one. It has to include “A listing and interpretation of the results of all communicable disease tests performed.” And it has to give “The name and address of the establishment that made the donor-eligibility determination.”

You will not find the donor’s name in it. The rule says these records “must not contain the donor’s name or other personal information that might identify the donor.”

So when a rep tells you a product was fully screened, you know what to ask to see. Ask for the code on the container, the eligibility statement and the summary of records.

A certificate of analysis is a different paper. It is the maker’s own record of what was tested on one lot and what those tests showed. I tell providers this: “If you ask a vendor for the certificate of analysis and they don’t want to give it, or they don’t have it, that’s your answer. Run away.”

## What is actually in a vial of Wharton’s jelly?

That is a question, and you should ask it as a question every time. The tissue inside a cord and the product inside a vial are two different things, because of everything that was done in between.

The anatomy chapter describes tissue in the cord, and it does not describe any product. We also did not find an FDA page that says what a given vial holds. So the answer has to come from the records for the lot.

A sales sheet for one of these products may use the words stem cells. Here is how I put it: “Stem cells are a category, not a product.” A category word tells you very little about one vial from one lot.

So ask about three things, in this order.

- The source. Is the product made from the jelly alone, or from the whole cord with its vessels and cover? Does each lot come from one donor?
- The processing. What was done to the tissue, step by step, and what was added? How is the product stored and shipped?
- What is counted. If the sheet prints a number, what exactly was counted, and by what method? Was it counted on the lot you were shown or on some other lot, and was that before or after storage?

You will not find a cell count in this post. A number on a brochure is a claim. Even a count on a lot record only tells you what one lab counted, and it says nothing about FDA status. We will not repeat a claim as if it were a fact.

We also will not tell you what the contents of a vial do in a patient, because no Wharton’s jelly product is FDA approved for any use.

## Is Wharton’s jelly the same as cord tissue, cord blood or stem cells?

No. These four terms get used as if they were one, and they are not.

- Wharton’s jelly is the soft connective tissue inside the cord.
- Cord tissue is a wider term. People use it for the cord itself, which holds the vessels, the jelly and the outer cover. So a product labeled cord tissue may hold more than the jelly.
- Cord blood is blood. FDA defines it as “[the blood contained in the placental blood vessels and umbilical cord](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/cord-blood-banking-information-consumers).” It is a different material from the jelly around those vessels.
- Stem cells is a category, as we said above, and it is not the name of any one product.

Why does the mix-up matter? It matters because the FDA status of one term does not carry over to another. FDA’s [list of approved cellular and gene therapy products](https://www.fda.gov/vaccines-blood-biologics/cellular-gene-therapy-products/approved-cellular-and-gene-therapy-products) includes cord blood products. When we checked that list on October 5, 2026, no Wharton’s jelly product was on it.

So when a brochure says umbilical, ask which of these four it means. We compare cord blood, cord tissue and Wharton’s jelly side by side in a later post in this series.

## Can I use Wharton’s jelly in my practice?

Here are FDA’s own words, from its [patient and consumer page on regenerative medicine therapies](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/important-patient-and-consumer-information-about-regenerative-medicine-therapies). FDA marks that page as current as of April 8, 2024.

The page names the kinds of unapproved products being marketed. Its list reads: “stem cells, stromal vascular fraction (fat-derived cells), umbilical cord blood and/or cord blood stem cells, amniotic fluid, Wharton’s jelly, ortho-biologics, and exosomes.”

What does FDA say it takes to give one of these products to a patient? It says, “FDA has repeatedly notified manufacturers, clinics, and health care practitioners of the need for Investigational New Drug applications (INDs) to legally administer these products.” An IND is the filing that lets a product be tested in people before it is approved.

The same page adds two short sentences. One is, “[Before approval, these products require FDA oversight in a clinical trial](https://www.fda.gov/vaccines-blood-biologics/consumers-biologics/important-patient-and-consumer-information-about-regenerative-medicine-therapies).” The other is, “These products require FDA licensure/approval to be marketed to consumers.”

So can you add Wharton’s jelly as a service? Nothing on FDA’s page supports that. There is no approved Wharton’s jelly product. FDA’s stated position is that an IND comes before a product like this is given to a patient.

What about your state? State law does not override federal law. State law in this field changes, sometimes more than once a year. Our reading of each state, with its sources and the date we checked, is on the [rules by state page](https://regenmedacademy.com/regenerative-medicine-laws-by-state/). It is a starting point, not legal advice.

FDA takes a similar position on exosome products, and we cover that in our post on [whether exosome products are legal to use in a clinic](https://regenmedacademy.com/are-exosome-products-legal-in-my-clinic/). The approval question for Wharton’s jelly gets its own post later in this series.

## What should I ask a vendor about a Wharton’s jelly product?

Let’s say a rep leaves a brochure for an umbilical cord product at your front desk. Your only job that day is to collect answers in writing.

- Which tissue is this made from: the jelly alone, or the whole cord?
- Does each lot come from one donor?
- Who made the donor eligibility decision, and may I see the eligibility statement and the summary of records?
- Which lab ran the donor tests?
- What are the processing steps, in order, and what is added to the tissue?
- If your sheet prints a count, what was counted, by what method, and on which lot?
- May I see the certificate of analysis for one lot?
- What is this product’s FDA status in your company’s view, and where is that in writing?

We did not come up with the idea of a written list for a vendor meeting. [Carla Mazzeo, PhD](https://regenmedacademy.com/dr-carla-mazzeo/), is on our science faculty, and the exosome vendor checklist is hers. We borrowed the idea of a written list from it, and the wording of the questions above is ours.

No answer on that list makes the product usable in your practice, because FDA’s position on INDs stays the same. Take what you collect to your own attorney, since a brochure cannot answer a legal question.

## What does Regen Med Academy teach about Wharton’s jelly?

## Frequently asked questions

### Who is tested when the donor is a newborn?

The birth mother is tested. The rule covers “a donor 1 month of age or younger,” and it says “you must test a specimen from the birth mother instead of a specimen from the donor.” So ask the vendor for the summary of records. It lists the disease tests that were run and how the lab read each one.

### Does donor screening mean a product is FDA approved?

No. Donor screening and testing are about keeping disease from spreading, and every donor tissue product has to deal with them. Approval is a separate review by FDA. A product can come from a screened and tested donor and still have no approval. No Wharton’s jelly product was on FDA’s approved list when we checked it on October 5, 2026.

### Is Wharton’s jelly an amniotic product?

No. Amnion is the membrane that covers the cord, and Wharton’s jelly is the tissue inside that cover. FDA’s patient page lists amniotic fluid and Wharton’s jelly as two separate items. Sales material sometimes groups all birth tissue under one name, so ask which tissue is in the product in front of you.

### What is a certificate of analysis?

It is the maker’s own record for one lot of a manufactured product. It should say what was tested on that lot and what those tests showed. It belongs to donor and manufactured products. There is no certificate of analysis for PRP that you prepare in the room from a patient’s own blood.

### Does a state law change what FDA says about Wharton’s jelly?

No. State law does not override federal law, so FDA’s position is the same in every state. A state can set who may perform a procedure under its own licenses. Our rules by state page gives our reading of each state, with its sources and the date we checked.

## Key takeaways

- Wharton’s jelly is the gelatinous connective tissue of the umbilical cord, the gel around the cord’s two arteries and one vein.
- As a product it is donor tissue, also called allogeneic, and it is not the patient’s own.
- Federal rules in 21 CFR Part 1271 require a donor to be screened and tested. For a newborn donor, the birth mother’s specimen is tested.
- Those donor rules are about the spread of disease, and meeting them is not an FDA approval.
- What is in a vial is a question about source, processing and what was counted. The answer is in the records for the lot.
- Wharton’s jelly, cord tissue, cord blood and stem cells are four different terms. The FDA status of one does not carry over to another.
- No Wharton’s jelly product was on FDA’s approved list when we checked it on October 5, 2026. FDA says INDs are needed to legally give these products to patients.
