|contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!|
Placenta and placental cord blood (umbilical cord blood, UCB) contains stem cells that can be harvested at birth (More? Placenta Development). The total amout of blood that can be collected is about 90 ml, from which stem cells can be collected, typed and stored in Cord Blood Banks. Both public and private Cord Blood Banks have arisen in this area. These cells provide a resource for bone marrow replacement therapy in many diseases, bone marrow transplantation was originally the only treatment available for many otherwise fatal diseases. Recently, cord blood transplantation has developed as a new alternative therapy for some of these same diseases.
Placental cord blood is a rich souce of haematopoietic stem cells for transplantation. Cord blood can collected at birth, with no impact on the mother or neonate, and stured in cord blood banks for later use.
BBC (UK) A brief article on Cord Blood stem cells and their therapeutic potential.
A useful guide (online PDF document) to stem cells was produced in a report by the National Institute of Health (NIH, USA, May 2000) Stem Cells: A Primer (PDF 1.89 MB) and more recently NIH has established a Stem Cell information page.
Note that placental cord Wharton's jelly can be also used to derive mesenchymal stem cells. These stem cells have been trans-differentiated into more advanced stages of germ cells by a simple two-step induction protocol using retinoic acid and Sertoli cell-conditioned medium.

Cord Blood Registries
Placental cord blood banks (2009)
Cord blood collection statistics began in 1994 and have been increasing ever since. In January 2007, there were 254,000 cord blood units collected in worldwide registries.
CBU Cord Blood Units
NVC Net Volume Collected of CBU Volume of the unit in milliliters; see note below.
TNC Total Nucleated Cells count of CBU The rounded number of nucleated cells in the units of 10 million.
CD34P Collected number of CD34+ cells of CBU Cell count after volume reduction; numeric value with decimal point in units of 1 million.
MONONUC Collected number of mononuclear cells of CBU The rounded number of mononuclear cells in the units of 10 million.
The list of diseases that were transplanted with cord blood include the following: Acute Lymphoblastic Leukaemia, Acute Myeloblastic Leukaemia, Adrenoleukodystrophy, Blackfan-Diamond, Cancer-miscellaneous, Chronic Myeloid Leukaemia, Chronic Lymphocytic leukaemia, Fanconi's Anaemia, Genetic disorders - miscellaneous, Hurler's Syndrome, Immune deficiency-Miscellaneous, Krabbe's disease, Lymphomas, Myelodysplastic Syndrome, Mucolipopolysaccharide deficiency, Osteopetrosis, Syndrome Severe Aplastic Anaemia, Severe Combined Immunodeficiency Disease, Storage disorders, Thalassaemia, Wiskott-Aldrich Syndrome (From: The Sydney Cord Blood Bank)
Australia has three cord blood banks (CBBs) located in Brisbane (Queensland), Sydney (New South Wales) and Melbourne (Victoria). AusCord is the Australian national network of umbilical cord blood banks and cord blood collection centres.
On August 9, 2001, at 9:00 p.m. EDT, the President announced his decision to allow Federal funds to be used for research on existing human embryonic stem cell lines as long as prior to his announcement (1) the derivation process (which commences with the removal of the inner cell mass from the blastocyst) had already been initiated and (2) the embryo from which the stem cell line was derived no longer had the possibility of development as a human being.
In addition, the President established the following criteria that must be met:
- The stem cells must have been derived from an embryo that was created for reproductive purposes;
- The embryo was no longer needed for these purposes;
- Informed consent must have been obtained for the donation of the embryo;
- No financial inducements were provided for donation of the embryo.
In order to facilitate research using human embryonic stem cells, the NIH is creating a Human Embryonic Stem Cell Registry that will list the human embryonic stem cell lines -- at varying stages of development -- that meet the eligibility criteria. Listed below are entities that have developed stem cell lines that meet the President's criteria and are therefore eligible for federal funding.

NIH Clinical Trials (May 2004) Launches Study of Hematopoietic Stem Cell Transplantation for Severe, Treatment-Resistant Lupus (NIAMS, May 13,2004)
A clinical therapeutic trial in the USA for hematopoietic stem cells in an autoimmune disease.
"A five-year study to see whether a therapy using transplantation of hematopoietic stem cells, blood stem cells found in bone marrow, can produce long-term remission for patients with severe, treatment-resistant systemic lupus erythematosus (or lupus), a rheumatic autoimmune disease that can affect the body's major organs. The study will include a basic research component to examine the roles of B and T cells, white blood cells in the immune system, in triggering lupus symptoms."
