Abstract Background and Purpose There are abundant hematopoietic stem cells (HSCs) in cord blood. It was known that HSCs continue to differentiate into common lymphoid progenitors (CLPs) and common myeloid progenitors (CMPs). Furthermore, the CMPs could differentiate into megakaryocyte erythroid progenitors (MEPs), and MEPs ultimately differentiated into platelets and erythrocytes. It had been reported that the proportion of HSCs in cord blood was higher than that in healthy pregnant women, so as the incidence of neonatal polycythemia in gestational diabetes mellitus (GDM) patients. We aimed to investigate the HSCs population and the change of their differentiation in the cord blood of neonates of GDM mothers. Methods In this study, we collected cord blood from GDM and healthy pregnant women at delivery. Totally 75 cases were included, in which 52 were for healthy control group and 23 were for GDM group. Then the number and differentiation status of HSCs in cord blood of the two groups were observed. HSC (CD45+ CD34+), CLP (CD45+ CD34+ CD7+) and CMP (CD45+ CD34+ CD33+) cells were identified and quantified by flow cytometry. Results Compared to healthy controls, HSC number in cord blood from GDM group were significantly increased (0.77±0.063% vs.1.28±0.176%，p=0.0113). The number of CMP cells which were differentiated from HSCs were higher than control (28.69±3.223% vs.46.43±4.927%, p=0.0033), while CLP cell number were lower (27.04±2.044% vs.21.11±2.406%, p=0.0475). Conclusion In conclusion, compared with non-diabetic pregnant women, there were more HSCs in the cord blood of the newborns of GDM patients, and the differentiation of HSCs to CMP cells was increased, while the differentiation to CLP cells was decreased. Those findings were probably caused by the high glucose microenvironment and insulin medication in pregnant women with GDM, and the HSCs differentiation changes might be influencing factors of the high incidence of neonatal erythrocytosis in GDM patients.

Objectives. The aim was to investigate neutrophil gelatinase-associated lipocalin (NGAL) levels in the serum and term placentas and its potential role in gestational diabetes mellitus (GDM). Methods. A total of 49 GDM subjects and 39 age-matched women with normal pregnancies were recruited. We examined serum concentrations of NGAL and tumor necrosis factor-α (TNF-α) in maternal blood and cord blood and their expression levels in the term placentas and umbilical cord. Results. Serum NGAL levels were significantly higher in GDM patients than in normal pregnant controls both in the maternal blood (4.80 ± 1.99 vs. 3.66 ± 1.13, P=0.001) and the cord blood (4.70 ± 2.08 vs. 3.85 ± 1.44, P=0.027). Moreover, serum NGAL levels exhibited a positive correlation with various parameters of insulin resistance. Maternal serum NGAL levels positively correlated with the NGAL levels found in the cord blood of the control (r = 0.399, P=0.012) and the GDM subjects (r = 0.349, P=0.014). Finally, the expression of NGAL protein levels in the placenta (1.22 ± 0.39 vs. 0.65 ± 0.23, P<0.001) and umbilical cord (0.65 ± 0.23 vs. 0.25 ± 0.10, P<0.001) were higher in GDM women than those noted in the control subjects. In the GDM group, maternal serum NGAL levels exhibited a positive correlation with placental NGAL mRNA and protein levels (r = 0.848, P=0.008; r = 0.636, P=0.011, respectively). Conclusions. NGAL may be an important adipokine involved in GDM and fetal development. The oversecretion of NGAL from the placenta may contribute to the elevated levels of serum NGAL in gestational diabetes mellitus.
