Abstract:

 Umbilical cord blood (UCB) contains hematopoietic and mesenchymal stem cells(HSCs,MSCs) that have proven useful clinically to reconstitute the hematopoietic system in children and some adults  .   Fifteen cord blood samples were collected from placenta of  newly delivered women in AlKadhemia hospital in Baghdad for normal vaginal delivery.      Mono nucleated cells (MNCs) were isolated by using density gradient centrifugation and the MNCs  count and viability  were  determinated by trypan blue.MNCs were cryopreserved using the cryoprotectant solution of 10% concentration of dimethyl sulfoxid (DMSO)using slow cooling and rapid thaw.  The aim of the present study is to collect, separate and enumerate the stem cells in cord blood(CB) and study the effect of cryopreservation on stem cells count and viability.   The results of the present study showed that the average cord blood volume collected was 81.66 ml. Mononuclear cell count ranged from 5.6-14.6 x106.Viability count of mononuclear cells was 93.9%.After three months of cryopreservation , the viability count on revival was 73.9%.This study represents an attempt to isolate  the stem cells from UCB.  The results of the present study  confirmed that  UCB provides a great source of stem  cells for  using in medical applications.
