Characterization of a novel rat cholangiocarcinoma cell culture model-CGCCA

Figure 1 MTT assay. Twenty-five weeks orally administrated TAA rat liver tissues cells have been harvested and successfully cultured. The cells followed a typical growth curve; lag, logarithmic, and stationary phases during culturing were estimated. Under series surveillance, a cell population doubling time of 32 h was determined (6 points at day 4, 5, 6, 7, 8, and 10).
