What is Cord Blood?
Cord Blood is the blood collected from placenta, it is left over in the placenta and in the umbilical cord after the birth of the baby. In the past, cord blood is disposed along with the placenta as clinical waste. Thanks to the advancement of medical science and biotechnology, the medical value of cord blood is unveiled.
Cord blood is rich of Hematopoietic Stem Cells (HSCs) which can differentiate into blood and immune system cells and have significant medical value. Up to 113 diseases such as cancers, blood-related, immunity and metabolic diseases can be treated by cord blood5. At present, over 60,000 cord blood transplants (incl. adults / children and autologous / directed allogeneic cases) have been performed worldwide5. The future application of cord blood will be in line with the advancement of regenerative medicine.
Most Asked Questions by Parents Related to Cord Blood Banking
Until June 2016, up to 113 diseases had been treated with cord blood transplants5,6. They could be divided into 7 categories, namely: Leukemia, Lymphomas, other Disorders of Blood Cell Proliferation, Inherited Disorders of Immune System, Inherited Metabolic Disorders, other Cancers and others.
Detail about 113 treatable disease please refer to Diseases Treated by Cord Blood Transplantation.
Cord blood and umbilical blood contain two different stem cells which are widely adopted in different medical aspects. Cord blood is a rich source of HSCs which can create the blood and immune cells. Cancers, blood-related, immunity and metabolic diseases can be treated by cord blood. Umbilical cord is a rich source of MSCs which can create structural and connective tissues. Apart from minimizing GvHD in directed and unrelated allogeneic cord blood transplants, MSCs can apply to chronic illnesses treatment, regenerative medicines as well as organ and tissue engineering. Since cord blood and umbilical cord are rich sources of different types of stem cells, they may help to repair the body in different ways.
Stem cells will stop all physiological activities and remain dormant in -196℃ liquid nitrogen. Therefore, the stem cells can be permanently stored theoretically19. Professor Hal E. Broxmeyer (microbiology and immunology) is a pioneer who advocates of cord blood stem cells cryogenic storage. He proved that stem cells stored for years were still very regenerative, indicating that the stem cells stored in 1985 and 1986 could still be applied to patients for transplant33.
On the contrary, there is no factual basis for the claim of stem cells being able to store permanently under -135℃. Noted that using the vapor nitrogen storage system would cause temperature fluctuation upon stem cells storage and thawing and seriously affect the viability of all samples' stem cells.
Almost all public cord blood banks, including worldwide large blood banks, use liquid nitrogen for stem cells storage.
