Abstract

Background: Cord blood contains high number of hematopoietic cells that after birth disappear. In this paper we have studied the functional properties of the umbilical cord blood progenitor cells collected from term and preterm neonates to establish whether quantitative and/or qualitative differences exist between the two groups. Methods and Results: Our results indicate that the percentage of total CD34+ cells was significantly higher in preterm infants compared to full term: 0.61% (range 0.15-4.8) vs 0.3% (0.032-2.23) p = 0.0001 and in neonates 32 wks GA: 0.95% (range 0.18-4.8) and 0.36% (0.15-3.2) respectively p = 0.0025. The majority of CD34+ cells co-expressed CD71 antigen (p
