Abstract:
Objective:To evaluate the effect of zinc ions on human umbilical vein endothelial cells biological functions.
Methods:The primary human umbilical vein endothelial cells were cultured with the ECM medium, and cells were divided into 8 groups: the control group(routine culture,n=3), 20 μmol/L zinc group(20 μmol/L zinc chloride solution was added into the cell medium, n=3), 40 μmol/L zinc group(40 μmol/L zinc chloride solution was added into the cell medium, n=3),80 μmol/L zinc group(80 μmol/L zinc chloride solution was added into the cell medium, n=3), 100 μmol/L zinc group(100 μmol/L zinc chloride solution was added into the cell medium, n=3), 200 μmol/L zinc group(200 μmol/L zinc chloride solution was added into the cell medium, n=3),300 μmol/L zinc group(300 μmol/L zinc chloride solution was added into the cell medium, n=3), 500 μmol/L zinc group(500 μmol/L zinc chloride solution was added into the cell medium, n=3). The cell proliferation curve was derived from real time cell analysis (RTCA). The viability value was obtained via CCK-8 reagent, and the migration distance was tested by scratch-wound assay while the adhesion function was detected by RTCA.
Results:(1)After 18 hours, RTCA showed that the proliferation cell indexes were 4.5±0.6, 3.7±0.4, 3.6±0.3, 2.5±0.4, and 2.5±0.4 in the 20, 40, 80, 100, and 200 μmol/L zinc groups, as compared with 3.5±0.3 in the control group (all P<0.05). Proliferation cell indexes were 0 in both of the 300 μmol/L and 500 μmol/L zinc groups. (2)After 96 hours, the viability were 1.21±0.05, 1.10±0.03, 0.99±0.05, 0.62±0.02, 0.45±0.04, 0.11±0.01, and 0.12±0.06, respectively in the 20, 40, 80, 100, 200, 300, and 500 μmol/L zinc groups, as compared with 0.75±0.05 in the control group (all P<0.05). (3)After 12 hours, the migration distances were (0.56±0.11),(0.96±0.07),(0.49±0.02), and (0.29±0.01)mm in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with (0.24±0.04)mm in the control group (all P<0.05). (4)After 18 hours, the adhesion cell index were 0.40±0.05, 0.31±0.01, 0.38±0.05, and 0.40±0.03 in the 20, 40, 80, and 100 μmol/L zinc groups, as compared with 0.24±0.04 in the control group (all P>0.05).
Conclusions:Zinc ions at lower concentration (≤80 μmol/L) can promote proliferation, viability and migration of human umbilical vein endothelial cells, but the adhesion function was not significantly affected by zinc ions. Zinc ions at higher concentration (≥200 μmol/L) can inhibit the cellular function of the human umbilical vein endothelial cells.
