Abstract
Objective:The adhesion of cells to cells and cells to stroma play very important role in the cell-cell information exchanges.Methods:The cell adhesion assay based on the 3 H-TdR incorporation assay was introduced. Firstly, coated cells were cultured to confluence in 96 well plate. After incubated with 3 H-TdR for 6h, the isotope labeled cells were added into plate wells and incubated for another 4 h. Then the un-adhered cells were removed by gently washing. The cpm was counted after cell harvest.Results:The cell adhesion assay based on the 3 H-TdR incorporation assay was very sensitive in the detection of cell adhesion. It could reflect the relative of cell to cell adhesion.Conclusion:The cell adhesion assay based on the 3 H-TdR incorporation assay is an useful method in the detection of cell to cell adhesion.
