Figure 5.

Levels of mRNA expression for the various cyclins. For each gene, the expression level was set to 1.0 for passage 6 CEF cells. The levels for other samples were then adjusted accordingly. A minimum of three independent RT-PCR experiments were analyzed using the NIH image software program and normalized using the expression levels of GAPDH. Differences ≤ 0.05 were considered significant. Different letters indicate significant differences.
