ABSTRACT
Objective To explore the effects of the stromal cell-derived factor on chemotaxis of cord blood ACl33+ cells.Methods The optimal SDF-1 concentration is detected in Transwell system.Migration was calculated from the number of cells found to have passed through an 8-um pore size polycarbonate membrane.Results The chemotactic rate of fresh cord blood AC133+ cells increases along with the concentration of SDF-1,however,it tends to be stable when the concentration of SDF-1 reaches 150 ng/ml.There is no difference in the chemotactic rate of cord blood AC133+ cells between the group with CXCR4-blocking antibody and the group without SDF-1.Conclusion Transwell Plate can simulate the phenomenon of cell crossing endothelium.The chemotactic rate of cord blood AC133+ cells increases progressively along with the concentration of SDF-1,however,the chemotactic rate tends to equability when SDF-1 reaches a certain concentration.The chemotactic rate does not have a marked change while continuing to increase the concentration of SDF-1.There is no difference in the chemotactic rate of cord blood AC133+ cells between the group using CXCR4-blocking antibody and the group without SDF-1.
