Leukemia, the most common form of childhood cancer, affects the blood-forming cells in the bone marrow. It is often treated with stem cell transplants that replace the patient’s bone marrow cells with stem cells donated by a healthy individual. Successful transplant depends on finding a donor who is a close genetic match to the patient. That’s a particular challenge for patients from racial and ethnic minority groups, who may die while waiting for a matching donor.
But a mostly-untapped source of genetically diverse stem cells is right under our noses: Blood left in the umbilical cord after a baby is
The extensive research on stem cells has revolutionised the way life-threatening diseases like leukaemia and aplastic anaemia can be treated.
But there are several steps before these diseases can be treated using stem cells.
To begin with, the Human Leukocyte Antigen (HLA)-typing of the patient is done. Doctors then get into the process of finding a matched donor from the computerised list made available to them by National Marrow Donor Programme (NMDP), U.S., and New York Cord Blood Bank.
If registration of potential bone marrow donors has been in place for a long time, the emergence of a number of cord blood
Cells grown in culture are not alone: They are constantly communicating with one another by sending signals through their culture media that are picked up and transmitted by other cells in the media. When thousands of cells are cultured together in a dish, there are hundreds of thousands of these signals present every minute, all competing to be heard.
Scientists trying to direct cells to do useful things — like causing stem cells to turn into neurons or heart cells — typically try to overcome these signals by adding their own exogenous factors. These exogenous factors are often added at

Expectant parents must make several important medical decisions. Among them: whether to have prenatal genetic testing, request pain medication during labor, strive for a natural birth or circumcise a male baby?
Perhaps one of the most overlooked parts of childbirth preparation is whether to save or donate the infant’s umbilical cord blood.
Umbilical cords are usually discarded as medical waste. But the potential uses for cord blood are growing, making it imperative that families understand their options, including whether to pay to have the blood stored for possible use in the event of their child’s illness

AUGUSTA, Ga. – Medical College of Georgia researchers are conducting the first FDA-approved clinical trial to determine whether an infusion of stem cells from umbilical cord blood can improve the quality of life for children with cerebral palsy.
The study will include 40 children age 2-12 whose parents have stored cord blood at the Cord Blood Registry in Tucson, Ariz.
Umbilical cord blood is rich in stem cells, which can divide and morph into different types of cells throughout the body, said Dr. James Carroll, professor and chief of pediatric neurology in MCG School of Medicine and principal investigator
