Hi Beryl,
According to this abstract 1-year disease-free-suvaval was similar using related donor peripheral blood stem cells, related donor bone marrow stem cells, unrelated donor marrow stem cells or cord blood cells.

In many other abstract like in these very interesting videos from AA and MDS International Foundation about transplantation they mention that cord blood isn’t much used for adults because you get so few cells from the cord after a birth.
