- Available source; safe and abundant in stem cells;
- No ethical restrictions for use;
- Low virus contamination, including cytomegalovirus (CMV) and Epstein-Barr (EB), in contrast to bone marrow;
- Source of readily available stem cells, eliminating the delays and uncertainties in the compatability search;
- : No malignant transformation of the human umbilical cord blood (hUCB) cells are observed in none of the transplant recipients;
- More immature cells: less of a potential for an immunological reaction to the receptor;
- Activity of telomerase (“cellular youth”).
• Younger cells (hUCB) – cellular activity for a longer period than those that receive stem cells from adult donors.
