Molecule that leads stem cells to bone marrow discovered
An ‘antenna’ molecule, which is capable of guiding blood stem cells to their natural ‘home’, the bone marrow, has been discovered. The discovery could improve the efficiency of umbilical cord stem cell transplants. This type of transplant is not efficient when there are not many umbilical cord stem cells present, since few of them are able to reach the bone marrow from the blood.
