An easy guide to some of the scientific terminology.
When stem cells are donated from one person and transplanted into another person to be used as a treatment for certain illnesses and conditions.
When stem cells are taken from a person and then transplanted into the same person to be used as a treatment for certain illnesses and conditions.
This takes place after birth and the umbilical cord has been clamped and cut and is the process of collecting umbilical cord blood using a tube with a needle on one end and a bag on the other.
This is the blood contained within the umbilical cord and placenta.
The process of freezing cord blood stem cells, at very low temperatures, so that it is safely stored for long periods of time.
In the Family Banking service all of the stem cells that are collected from your baby’s cord blood are stored for 25 years for your family’s exclusive use.
This relates to the creation of blood in the body. A haematopoietic stem cell is one that can divide and produce blood cells.
Is a cancer of the blood forming system, the blood forming system is found in the bone marrow. In leukaemia, some blood cells do not grow properly, but remain within the bone marrow and continue to reproduce in an uncontrolled way. These cells fill up the bone marrow and prevent it from making healthy white blood cells. This means the body is less able to fight off infections. There are many different kinds of leukaemia.
Tissue match / Tissue matched
Refers to a tissue typing match, the scientific term for this is HLA-type match. Tissue types must be matched as closely as possible between the person donating stem cells and the person receiving them to reduce the risk of rejection.
Blood taken from the mother, which is completely separate to the blood taken from the umbilical cord.
This is the blood that circulates around the arteries and veins of the body.
The way in which the stem cells found in umbilical cord blood are extracted from the blood, counted, tested and prepared for long-term storage.
This is about treatments in development that, in the future, may be able to treat diseases and injuries by using stem cells to repair or regenerate damaged cells and tissues in the body.
A special kind of cell that can divide many times to make exact copies of itself, or to make specialised cells that do a particular task in the body for example a blood cell, bone cell or liver cell. Some people call stem cells ‘master’ cells or ‘blank’ cells because they can change into so many different types of cell.
At Virgin Health Bank we test the mother’s blood for six viruses. We also test the baby’s blood to see how many stem cells there are, how healthy they are and in our community banking service we also identify what tissue type they have.
Tissue type / typing
Tissue types are similar to blood types. For a person to receive a transplant of cells or tissue from someone else, they must have the closest possible tissue type 'match'. Our tissue type is determined by our DNA. There are millions of possible tissue types, so a large bank of stem cells increases the chance of finding a close match when one is needed.
Taking cells, tissues, or organs and placing them into the same person or a different person to treat disease.
Stems cells collected from the umbilical cord are properly described as a ‘cord blood stem cell unit’
