Doubling times and slope values in the various media. The values were obtained at three stages, 0–130 h, 130–260 h, and 260–300 h, and the whole proliferation curve at 0–300 h. There were no significant differences between the doubling times (A) and slope values (B) in 5, 7, or 10% aPRP, or 10% FBS, but a significant difference in 2% aPRP.
