Abstract
Objective
To identify and quantitatively determine Mesenchymal stem cells (MSCs) in the umbilical cord blood (UCB) of neonates born at different gestational periods.
Methods
UCB was collected at birth in neonates of three different gestational groups. The mononuclear cells (MNCs) were phenotypically analyzed by flow cytometer.
Results
The yield of total MNCs did not differ much with gestation; the average values were 22.6 ± 6.48 × 106 cells/ml. The MSCs were significantly higher in the lower gestation group. These were 0.0219 ± 0.012 %, 0.0044 ± 0.003 % and 0.0022 ± 0.003 % in 28 to 31 wk, 32 to 35 wk and >36 wk, respectively (P = 0.00). There was a significant inverse correlation between the gestational age and the presence of MSCs with a correlation co-efficient of −0.54 (P = 0.0001).
Conclusions
The MSCs population was significantly higher in infants born at lesser gestation than those born at term gestation.
