-        Avoidance of histocompatibility problems. As for adult, cord blood & animal cells, histocompatibility has been always a major problem in transplantation, causing rejection of transplanted organs.
Thus transplantation of cord blood, bone marrow and animal cells… etc require special measure to suppress the recipient immune system.

-        Embryonic Stem Cells curative effects last for months to years. In some cases, engraftment probably stays for life.

-        Stem Cells from self. 
There is no problem of rejection. But adults have few stem cells and their ability to differentiate is limited.

-        Cord Blood Stem Cells
They are useful for only blood system disorders. They have a 50% chance for use by parents, 25% chance for siblings & approximately 1 in 50,000 chance for unrelated people.
