Growth curves of nonadherent cells generated from AC133⁺ progenitor cells in liquid cultures with stem cell growth factor and vascular endothelial growth factor.

Proliferating nonadherent cells were obtained with the supernatant, and the number of cells per mL was counted. Three independent experiments are shown. Evaluation of the cell count was performed at various time points, depending on the individual growth pattern in each experiment. Results of 3 independent experiments are shown. Abbreviations: Pat. 1-3, patient 1-3.
