The UCB contains about 60-80 cc of Cord Blood (CB). UCB is harvested at birth by “waterworks” method [16]. The contamination risk during UCB drawing is whopping low, thereabout 15% [16]. UCB has been reported in literature as a source of various stem cells [17]. Therefore, UCB contain particular precursors of red, white blood cells and platelets with specific and selective abilities that are not shown by the same forerunners from peripheral blood (PB) and/or from bone marrow (BM) [18; 19; 20; 21; 22]. UCB contains erythrogenic precursors, megakaryocytic precursors white cells precursors and are enriched with regulatory T cells allowing the control of alloimmune response (Tregs) [23; 24]. Particularly, in comparison to the same forerunners from PB or BM; these evidences permit smashing therapeutical applications [25]. A greater percentage of CD34+ and CD105+ cells (markers of stemness) is evident in UCB [18]. The large amount of stem cells contained conferred to UCB outstanding regenerative properties.
