7. Lung diseases. From human embryonic stem cells, researchers in Texas have created transplantable sources of lung cells in the lab. Those lung cells could potentially be used to repair damage brought on by a variety of pulmonary conditions or by lung trauma resulting from a car accident, bullet wound, or sports injury. Unpublished studies using such cells have shown promise for tissue repair in mice with acute lung injury, the group reports.
In 1988, a 5-year-old named Matthew with a rare type of anemia received umbilical cord blood cells from his newborn sister, who didn’t have the disease. That transfer, called an umbilical cord blood transplant, worked, and the boy was soon free of the disease.

Given the difficulty in estimating the need for using one’s own cord blood cells for transplantation, private storage of cord blood as “biological insurance” is unwise. However, banking should be considered if there is a family member with a current or potential need to undergo a stem cell transplantation.
Options for Umbilical Cord Blood Banking and Donation—As expectant parents, learn how umbilical cord blood can help others through public donation, family (private) cord blood banking, or directed donation for a biological sibling.
If you intend donating umbilical cord blood for preservation and later use, you should let your doctor know by your 34th week so that they can help make any arrangements with a cord blood bank. Once you and your doctor have decided on which cord blood bank to use, you will often be sent informational reading materials from the cord blood bank for further education regarding the process of cord blood harvesting.
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.
In recent years, umbilical cord blood, which contains a rich source of hematopoietic stem and progenitor cells, has been used successfully as an alternative allogeneic donor source to treat a variety of pediatric genetic, hematologic, immunologic, and oncologic disorders. Because there is diminished risk of graft-versus-host disease after transplantation of cord stem cells using matched related donors, the use of less-than-completely matched HLA cord blood stem cells may incur less risk of graft-versus-host disease than mismatched cells from either a related or unrelated “walking” donor, although this remains to be proven. Gene-therapy research involving modification of autologous cord blood stem cells for the treatment of childhood genetic disorders, although experimental at the present time, may prove to be of value. These scientific advances have resulted in the establishment of not-for-profit and for-profit cord blood–banking programs for allogeneic and autologous cord blood transplantation. Many issues confront institutions that wish to establish or participate in such programs. Parents often seek information from their physicians about this new biotechnology option. This document is intended to provide information to guide physicians in responding to parents’ questions about cord blood donation and banking and the types and quality of cord blood banks. Provided also are recommendations about appropriate ethical and operational standards, including informed consent policies, financial disclosures, and conflict-of-interest policies for physicians, institutions, and organizations that operate or have a relationship with cord blood–banking programs.
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.
Back in the 1980s, umbilical cord blood caught the attention of researchers who suspected that the often-discarded tissue could be a valuable source of shape-shifting stem cells. These cells, which can become several different types of blood cells, are similar to the specialized stem cells found in bone marrow that can churn out new blood cells. Such stem cells are found in adult blood, too, but not as abundantly.
Priority shipping: Cord blood companies that use priority shipping services have families ship them cord blood in a heavily insulated box, which arrives at the cord bank at a certain time, but does not guarantee that the blood remains at a certain temperature.
Families with a history of diseases can greatly benefit from cord blood banking, as an insurance policy against possible future diseases. However, cord blood banking is expensive, can’t be used to treat everything, and your child may not even need it—at private cord blood banks, most is eventually discarded. Lastly, you should be aware that if the child develops certain genetic diseases, the cord blood will have the same genetic flaws.
Cord blood can only be collected at birth, that’s why it’s important to do your research well before your baby’s due date. Watch this short video to learn exactly how cord blood is collected, processed and stored.
That may sound expensive, but the cost of processing cord blood and storing it in medical freezers for years on end is considerable. Even public cord blood banks say the initial collection, processing, and storage cost them about $1,500 per unit of cord blood.
Regenerative therapy is the practice of delivering cells and cell products to renew diseased or damaged tissues in a specific area. It is one of the fastest growing fields of medical research. Each year, new regenerative therapies using stem cells from cord blood and cord tissue enter into clinical trials for the treatment of chronic and life-threatening diseases. If proven successful, these clinical trials will lead to approval from the Food and Drug Administration (FDA). With FDA-approval, these treatments can then be administered as a general practice.

Proponents of cord blood banking are convinced that instead of being medical waste, the fetal cells within are biological gold. In this post, and the two that follow, I’ll take a look at the evidence for those claims, and sort through some of the questions that arise as parents consider whether to bank their baby’s cord blood.
An accredited lab. In the United States, the FDA requires all public banks to have a Biologics License Application, but not private banks, though they are registered and inspected. Both public and private banks should have extra accreditation, which means banks are evaluated for the quality and accuracy of work. The two companies that handle accreditation are the American Association of Blood Banks (AABB) and the Foundation for the Accreditation of Cellular Therapy (FACT). Look for a bank with its own lab (some banks use labs at other banks), which means more regular quality control and testing standards.
Right after the cord is clamped and cut, your medical practitioner uses a needle and gets it inserted into the umbilical vein of the cord. Only that part is cut which is still attached to the placenta. High quality and proper needles are used and they do not go anywhere near your baby.
The “cell recovery rate” is often used to compare processing methods. Expressed as a percentage, the cell recovery rate tells you how many cells are retrieved from the original cord blood collection, once plasma has been removed and red blood cells have been reduced or removed. It is expected that some cells will be lost during processing, and most processing methods have published cell recovery rates between 80%—99%
The main disadvantage of cord blood transplants is that they take at least a week longer to “engraft”, which means repopulate the patient’s blood supply so that cell counts reach minimum acceptable levels. The longer engraftment time is a risk because it leaves the patient vulnerable to a fatal infection for a longer time.
Are public banks and family banks the same, except for who may use the cord blood and the cost to the parents? No. Public banks are subject to much higher regulatory requirements, and compliance with regulations carries costs. At a family bank you pay the bank enough to cover the cost of storing your baby’s cord blood, plus they make a profit. When you donate to a public bank, it costs you nothing, but the bank pays more on processing each blood collection than at a family bank. Let’s look at the steps that take place in the laboratory.

A few years ago, cord blood was simply discarded as medical waste after a birth. However, in the past few years, doctors have recognized that the stem cells have unique qualities which can be used in the treatment of certain cancers. The most common medical use is for transplantation in many situations where bone marrow is considered. In the future, it is possible that scientists will discover more diseases that can be cured with cord blood.
