Background and the

Transplanting Process

Umbilical Cord Blood

Studies of umbilical cord blood began in the 1960s

About 1 in 3 hematopoietic stem cell transplants are done with cord blood

The blood that is left in the placenta and umbilical cord can be taken and stored to be used for a stem cell transplant later in life

Transplant Process

• Pre-Transplant

• Patients receive other forms of treatment

• Cord Blood is obtained

• Transplant

• Patient receives the cord blood intravenously

• Post-Transplant

• Stem cells travel to the patient’s bone marrow

• Stem cells produce new WBC, RBC and platelets

First Cord Blood Transplant

• In 1988, a pediatric patient with Fanconi’s Anemia was successfully treated with a transplant of hematopoietic stem cells (HSC) from umbilical cord blood (UCB)

• Fanconi’s Anemia: develops because of damage done to the bone marrow which is causing the bone marrow to slow or stop new blood cell production

• The Ende brothers are accredited with clinical observation, establishing the scientific basis of the observation and performing the first transplant

• Dr. Broxmeyer is accredited for his studies on the storage of the UCB

• Dr. Gluckman is accredited for her efforts that established the transplantation of HSC from UCB as an accepted therapy

Uses For Cord Blood

• Treatment for over 80 diseases

• 1988 – 1 disease

• 2007 – 40 diseases

• 2010 – 80 diseases

• Not a cure but regenerates damaged tissues and restores lost function after injury or illness.

• Also used to regenerate healthy blood and immune systems after being damaged by diseases.

• Mostly used in children and small adults because not enough blood can be acquired from umbilical cord that is needed for the adult

USE IN AUTISM

• Unlike other medications that focus to control the behavior, targets the observed molecular mechanisms.

• Abnormal neurotransmitter regulation, mitochondrial dysfunction, bloodbrain barrier disruptions

• Study

• Combined transplantation of human cord blood mononuclear cells

(CBMNCs) and umbilical cord derived mesenchymal stem cells (UCMSCs)

• Improved behavior and function

• Safe to use

USE IN CEREBRAL PALSY

• Umbilical cord blood shown to lessen the impact of injury and facilitate neural cell repair resulting in improved function for patients with cerebral palsy

• Study

• Peripheral mononuclear blood stem cells used

• Resulted in functional improvements

• Safe to use

USE IN HEART FAILURE

• CB stem cells are capable of giving rise to hematopoietic, epithelial, endothelial and neural tissues

• Study

• Cord blood-derived unrestricted somatic stem cells (USSC) used in patients with acute ischemic myocardium

• Mesenchymal stem cells

• Functional improvements observed but not full recovery

USE IN STROKE

• Help in stroke recovery and brain repair by angiogenesis and neurogenesis with restoration to cortical tissue

• Study

• CD34+ of umbilical cord blood

• Successful outcomes in animal testing

USE IN OSTEOARTHRITIS

• Allogenic mesenchymal stem cells from donated human umbilical cords are administered into the affected joint(s) (intra-articular injection) and intravenously

• Vet-Stem tested and uses stem cells on horses with various joint deformities to accelerate healing

• Stem cells can protect cartilage from further destruction and facilitate regeneration

• Typical treatment protocol at Stem Cell Institute is about 5 days

(Riordan, 2012)

USE IN RHEUMATOID ARTHRITIS

• Other treatments have long-term adverse effects and do not address the issue of damage that has already occurred

• Mesenchymal stem cells produce anti-inflammatory agents, which act locally and do not suppress the immune response of the patient’s whole body

• Induce the production of T regulatory cells, a type of immune cell whose function is to protect the body against immunological selfattack

• Typical treatment protocol is 4 days

(Riordan, 2012)

USE IN SPINAL CORD INJURY

• Typical treatment protocol calls for 16 intravenous and intrathecal injections over the course of 4 weeks and uses a combination of umbilical cord derived stem cells and bone-marrow derived stem cells

• Intrathecal injections enable the stem cells to bypass the blood-brain barrier and migrate to the injury site

• Study

• Treatment was effective in 13 out of 22 patients (81.25% effective in incomplete

SCI, not effective in any patients with complete SCI)

• Patients reported significantly improved tactile sensation, motion and activities of daily living

• Real-life Success Story: Jamie Richie

Ethical Issues

PROS AND CONS OF BLOOD BANKING https://www.youtube.com/watch?v=Bnz

RzKsvlDo&index=44&list=PLturoXTpuYxD

ZkWOka_1SJ1icT-fxZqfP

Benefits

• Proven to treat hematopoietic diseases

• One umbilical cord generally contains enough stem cells to treat a child or small adult

• Previously, treating with two different donors has been effective which is reassuring in showing how adaptable cord blood cells are

(Apurva, 2009)

Disadvantages

• Expensive

• Chance that patient is exposed to a rare genetic disorder of the immune system or blood

• It may take a decade or two before there is a definite cure to deadly diseases

• The average-sized or larger adults were not thought to be able to benefit from this type of treatment

Ethical Areas to Think About

• Respect for human dignity and integrity

• Autonomy

• Justice and Solidarity

• Beneficence

• Non-maleficence

• Proportionality

(Petrini, 2013)

Cord Blood: Ethics

Justice

• Sufficient donations from different ethic groups

• Public storage when possible

(Petrini, 2013)

Cord Blood: Ethics

• Public or Private cord banking

• Public: Even discarded blood can benefit

• Private: The use for self is rare (0.005%)

(Petrini, 2013)

Blood Banking. Obstet

Gynecol 2009.

Cord Blood: Ethics

• Informed Consent

• Autonomy: right to self-determination

• USA: Laws aimed at educating parents about CB

• Process of obtaining informed consent should begin BEFORE labor and delivery

(Petrini, 2013)

Business On Hope

• New model of business that sells only “the hope on future use.”

• High use of Propaganda or Persuasion by private blood bank company’s on potential clients.

Misinformed Mothers

• Claim 1: Your child will most likely need their stored blood, the one company claims 1 in every 50 children.

• Claim 2: The child can use their own cord blood to treat leukemia.

• Claim 3: Stem cells in cord blood can be used as a cure-all for adults in treating many diseases.

• Claim 4: Finding a stem cell donor is often impossible.

• The Society of Obstetricians and Gynecologists and The American Academy of Pediatrics does not recommend cord blood banking.

Proposed Changes

“DUTY TO FEEDBACK” CHANGES IN LAW FOR THE

COMMERCIAL SECTOR

Allow donors to have the right to know what exactly their donations will be used for and how they are being used.

Allow donors to obtain profits from products or tests developed from their samples.

• A donor should have the right to know if the researcher has come across a potential risk for their health within the study.

Cord Blood Cell Stories

The Dones’ Story

• Tracey and Victor’s son Anthony diagnosed with Osteopetrosis at 4 months old

Osteopetrosis, "stone bone", also known as marble bone disease and Albers-

Schönberg disease, is an extremely rare inherited disorder whereby the bones harden, becoming denser

• Chose to save and store Anthony’s cord blood at birth

• Why were they unable to use the stem cell’s from the cord blood

…?

Stem cells contained the same genetic defect that caused his condition

"The materials provided by the bank said this was Anthony's life insurance and could save him if he needed it. They never mentioned that the cells could be diseased.”

Jessie Quinn’s Story

• Mixed race woman Diagnosed with Acute Myelogenous Leukemia as an adult and was selected to participate in a study done by the SCCA working with cord blood transplants in Adults

• The nature of cord cells is unique (cells haven’t been educated against foreign invaders like bacteria and viruses)

• Naïve immune system of cord blood means that close HLA tissue-type

DNA matching is much less important for cord blood than it is for bone marrow transplants

• It takes more time to restore a patient’s blood counts after cord blood transplantation than with bone marrow or adult blood cells.

This makes cord blood transplant patients more vulnerable to infections early.

• Doctor’s used a public cord blood bank with 2 units of primary cord blood and one unit of “expanded” cord blood (to overcome the delay in WBC production/decrease the risk of Jessie acquiring an infection soon after transplantation)

• Expanded cord blood cells are frozen and made readily available for patients

After hearing our presentation, would you bank your child’s cord blood?

A. Yes

B. No

If you answered yes, would you choose private or public banking?

A. Private

B. Public
