Introduction
Placenta and placental cord blood (umbilical cord blood, UCB) contains stem cells that can be harvested at birth (More? Placenta Notes). 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.
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 (note large size - 4.84 Mb) and more recently NIH has established a Stem Cell information page.
Some Recent Findings
Cord Blood Registries
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.
Diseases
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
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.

The Australian Health Ethics Committee was approached by human research ethics committees (HRECs) seeking advice on how to review research protocols that involve stem cell research. The following guidance is interim. Formal guidelines will be developed by AHEC in the context of its review of the 1996 NHMRC Ethical guidelines on assisted reproductive technology.
