RESUMO
The aim of the study was to analyze the influence of oxygene partial pressure (p02), base excess (BE) and buffer base (BB) parameters of cord blood obtained perinatally on quantity of obtained cells and focus on the perfect donor criteria. The study included 50 pregnant women aged between 18 and 38 years in which spontaneous labors and elective cesarean sections were performed. Umbilical cord blood was collected immediately after the women were delivered of newborns. The cells were analyzed in the Polish Stem Cells Bank in Warsaw. In the study group of patients different stem cells viability levels did not differ significantly in terms of pO2, BB and BE level, however, there was a trend that the higher the viability the lower BE value. The experiment showed also that the cord blood (CB) oxygenation scope is vitally important for the CB cells viability.
