Abstract:
Objective:To study the relationship between the cell density and the cell proliferation phenotype. Methods: Plate clonality assays was used to measure the impact of cell density to cell clonality and cell cycle in BT325、786-0、293、C6 and NIH3T3 cell lines. Results: The clonality decreased when the cells grown to confluence in NIH3T3 and 7860 cell lines respectively.It seem need more cells to decrease the clonality in 293 cell line but there is no relationship between cell density and cell clonality in BT325 and C6 cell lines.Cell cycle analysis show that cell density have no effect on BT325 and C6 but on 786-0、293 and NIH3T3 cell lines. Conclusion: There might exist preventer or preventers,which is proportional to the number of cells,of immortal stem cell to expand.In addition,the rate of stem cell expansion is proportional to that of cell mitosis in immortal cell lines.
