Whether UCM cells are MSC-like or fit into a unique niche is currently not clear. For example, when the vital stain Hoechst 33342 was used in the dye exclusion test, about 20% of UCM cells were found to exclude dye (28). About 85% of the UCM cells expressed CD 44, the hyaluronate receptor marker found on several stem cell populations, and about 85% of the cells expressed ABCG2, the receptor thought to mediate dye exclusion. Attempts to enrich the Hoechst-dim cells were partially successful, with maximal enrichment at about 32%. It is assumed that culture conditions are the limiting factor for further enrichment of what is assumed to be the most primitive populations.
“One of the wonderful things about cord blood is that unlike bone marrow, you don’t always need a perfect match in order for it to work,” says Dr. Kurtzberg, who performed the first unrelated cord-blood transplant in the U.S. And it was a public donation that ultimately saved Anthony Dones. Within a week of starting a search, the National Cord Blood Program, a public bank operated by the New York Blood Center, found a “close enough” match. Had the now-3-year-old been forced to rely on a bone-marrow match, he might still be waiting.
Since most banks require mothers to sign up for donation between the 28th and 34th week of pregnancy, families must decide to donate ahead of time. If you are considering a public bank for your child’s cord blood, contact the bank and make sure you still have time.
Mesenchymal cells have been reported to act as supporting cells that promote the expansion of other stem cell types. For example, MSCs and MSC-like cells support ex vivo expansion of hematopoietic stem cells (28,69–71). When co-grafted, MSCs and MSC-like cells support in vivo engraftment of hematopoietic stem cells, too (23,43,72). This work suggests that MSCs from a variety of sources, including umbilical cord, may facilitate engraftment of hematopoietic stem cells. This addresses two significant problems found in umbilical cord blood transplantation: (1) getting enough cells to engraft an adult and (2) increasing the speed of engraftment (12,73). Theoretically, cografting or ex vivo expansion may enable transplantation of cord blood units into larger patients and speed the engraftment in other patients.
Recently the minimal defining characteristics of MSCs was the subject of a blue ribbon panel of scientists (24). This panel ascribed three defining characteristics to MSCs. First, MSCs are plastic-adherent when maintained in standard culture conditions. Second, MSCs express the cell surface markers CD105, CD73, and CD90 and lack expression of CD45, CD34, CD14 or CD11b, CD79 or CD19, and HLA-DR. Third, MSCs differentiate to osteoblasts, adipocytes, and chondroblasts in vitro. As shown in Table 1, mesenchymal-like cells collected from the umbilical cord, placenta, and from umbilical cord blood, perivascular space, and placenta all share a relatively consistent set of surface markers, which is apparently consistent with the hypothesis that they are MSC-like.
Stem cells are injected into the veins during a peripheral blood transplant, and naturally work their way to the bone marrow. Once there, the new cells start increasing healthy blood count. Compared to bone marrow transplants, cells from peripheral blood are usually faster, creating new blood cells within two weeks.

Your adult cells have one disadvantage to cord blood cells – they cannot change their cell type. When stem cells from cord blood and tissue are transplanted, they adjust to fit the individual patient and replace damaged cells. Adult stem cells are also older, which means they have been exposed to disease, and may damage patients after the transplant. Compared to cord blood cells, adult cells have a higher chance for graft-versus-host disease.
While banking cord blood is a new experience for many parents, it is a simple one. After all, most mothers are worried about how the delivery will go and don’t want to also be worried about the details of collecting, processing and cryo-preserving their babies’s cord blood. Thankfully, the healthcare provider and the cord blood bank do most of the work. Here are the steps found in cord blood banking:
Much research is focused on trying to increase the number of HSCs that can be obtained from one cord blood sample by growing and multiplying the cells in the laboratory. This is known as “ex vivo expansion”. Several preliminary clinical trials using this technique are underway. The results so far are mixed: some results suggest that ex vivo expansion reduces the time taken for new blood cells to appear in the body after transplantation; however, adult patients still appear to need blood from two umbilical cords. More research is needed to understand whether there is a real benefit for patients, and this approach has yet to be approved for routine clinical use.
While donating cord blood is honorable, there is a lot people do not know about the public option. Most public cord blood banks have a limited number of collection sites, and they only retain a small number of collections because of volume and other criteria that must be met. Once cord blood is donated, it is highly unlikely that the donation can ever be attained by the donor or his or her family if the need arises. In addition, it may be hard to find another viable match from what is publically available. While donating is free, retreiving a cord blood sample from a public cord blood bank is not and pales in comparison to the overall cost of privately banking cord blood. These are just some of the reasons why privately banking cord blood may be a better option for some families.

Please note: ClinImmune Labs – University of Colorado Cord Blood Bank – CariCord’s activities for New York State residents are limited to collection, processing, and long-term storage of umbilical cord tissue. Possession of a New York State license for such collection, processing, and long-term storage does not indicate approval or endorsement of possible future uses or future suitability of umbilical cord tissue-derived cells.
They aren’t the only ones questioning the business practices of private cord-blood banks. Both the American College of Obstetricians and Gynecologists (ACOG) and the American Academy of Pediatrics (AAP) issued statements in the late 1990s opposing the use of for-profit banks — and criticizing their marketing tactics. Instead, they recommended that parents donate cord blood to public banks, which make it available for free to anyone who needs it. Globally, other organizations have done the same. Italy and France have banned private cord-blood banking altogether.
Importantly, ESCs are the de facto pluripotent cells for biomedical research. Proponents state that ESCs will enable cell-based therapeutics and biopharmaceutical testing/manufacturing. In contrast, biomedical research conducted using postnatally collected tissues and stem cells has generated less controversy and enjoyed more therapeutic applications to date. This is likely owing to the fact that blood and bone marrow stem cells were found to rescue patients with bone marrow deficiencies about 40 yr ago (8,9). The result of this work produced the national bone marrow registry, which was established in the United States in 1986.
We have 12- and 24-month in-house payment plans to spread the initial cost out over time. They require no credit check and begin with little money down. Starting at approximately $2.50 a day, you can help safeguard your baby’s future. After the term of the payment plan, you are then only responsible for the annual storage fee, which begins at approximately $12 a month depending on which services you have chosen.
It depends on who you ask. Although commercial cord blood banks often bill their services as “biological insurance” against future diseases, the blood doesn’t often get used. One study says the chance that a child will use their cord blood over their lifetime is between 1 in 400 and 1 in 200,000.
Whole genome sequencing is the process of mapping out the entire DNA sequence of a person’s genome. This test can show what type of health concerns we might face and most importantly how we can improve our health and quality of life.
Pro: It gives you that peace of mind that if anything did happen to your child, the doctors would have access to their blood. This could potentially be a great benefit, and you would have no idea what would have happened if it weren’t for this blood.
Private or family banks store cord blood for autologous use or directed donation for a family member. Private banks charge a yearly fee for storage. Blood stored in a private bank must meet the same standards as blood stored in a public bank. If you have a family member with a disorder that may potentially be treated with stem cells, some private banks will store the cord blood free of charge.
There has been considerable debate about the ethical and practical implications of commercial versus public banking. The main arguments against commercial banking have to do with questions about how likely it is that the cord blood will be used by an individual child, a sibling or a family member; the existence of several well-established alternatives to cord blood transplantation and the lack of scientific evidence that cord blood may be used to treat non-blood diseases (such as diabetes and Parkinson’s disease). In some cases patients may not be able to receive their own cord blood, as the cells may already contain the genetic changes that predispose them to disease.
There’s a network of public cord blood banks in the United States that can take your donation. Most public banks are nonprofit organizations, and all public cord blood banks must meet stringent quality standards.
At present, the odds of undergoing any stem cell transplant by age 70 stands at one in 217, but with the continued advancement of cord blood and related stem and immune cell research, the likelihood of utilizing the preserved cord blood for disease treatment will continue to grow. Read more about cord blood as a regenerative medicine here.
Current applications for newborn stem cells include treatments for certain cancers and blood, metabolic and immune disorders. Additionally, newborn stem cell preservation has a great potential to benefit the newborn’s immediate family members with stem cell samples preserved in their most pristine state.
Each year, thousands of people are diagnosed with leukemia, lymphoma, or certain immune system or genetic metabolic disorder. Many of these patients need an umbilical cord blood or bone marrow transplant (also called a BMT). Because the qualities that make a suitable match for bone marrow or umbilical cord blood are inherited, a match from a sibling or other family member is often checked first. However, 70 percent of patients will not find a matching donor in their family. For these patients, a transplant of bone marrow or cord blood from an unrelated donor may be their only transplant option.
With public cord blood banks, there’s a greater chance that your cord blood will be put to use because it could be given to any child or adult in need, says William T. Shearer, M.D., Ph.D., professor of Pediatrics and Immunology at Baylor College of Medicine in Houston. Cord blood is donated and is put on a national registry, to be made available for any transplant patient. So if your child should need the cord blood later in life, there’s no guarantee you would be able to get it back.
A major potential application of stem cells in medicine is for “tissue engineering,” in which the ultimate goal is to provide off-the-shelf tissues and organs. UCM cells demonstrate excellent cell growth properties on bioabsorbable polymer constructs (75). UCM cells were used to seed blood vessel conduits fashioned from rapidly bioabsorbable polymers and grown in vitro in a pulse duplicator bioreactor (76). Recently, living patches engineered from UCMS cells and cord-derived endothelial precursor cells have been described for potential use in human pediatric cardiovascular tissue engineering (77,78).
Fill out medical history sheets. The bank will ask you and your doctor to fill out medical forms that cover your infant, adolescent, and adult health. This helps the bank understand your general medical health to see if your child’s cord blood is useable in treatment. Overall, public banks usually accept healthy mothers without a history of severe inherited conditions.
* Annual storage fees will be charged automatically to the credit/debit card on file, on or around your baby’s birthday, unless you’ve chosen a prepay option and are subject to change until they are paid.
Marketing materials by Viacord and Cord Blood Registry, the two largest companies, do not mention that cord blood stem cells cannot be used by the child for genetic diseases, although the fine print does state that cord blood may not be effective for all of the listed conditions.
The Medical Letter On Drugs and Therapeutics also recently addressed aspects of public and private cord blood banks, asking the question: “Does Private Banking Make Sense?” After citing various statistics on the actual uses of privately stored cord blood, they concluded that: “At the present time, private storage of umbilical cord blood is unlikely to be worthwhile. Parents should be encouraged to contribute, when they can, to public cord blood banks instead.” [Access The Medical Letter at www.medicalletter.org].
According to Cord Blood Registry, cord blood is defined as “the blood that remains in your baby’s umbilical cord after the cord has been cut, is a rich source of unique stem cells that can be used in medical treatments.” Cord blood has been shown to help treat over 80 diseases, such as leukemia, other cancers, and blood disorders. This cord blood, which can be safely removed from your newborn’s already-cut umbilical cord, can be privately stored for the purpose of possible use in the future for your child or family member. (It can also be donated to a public bank, but this is not widely available)
