Figure 3

The probability ratios between D, P, C, I states of the prostate cancer model. The ratios are calculated by Eq. (15) with heights of potential barriers listed in the table of Fig. 2, where the values are normalized by the I state. We consider noise intensities: ε = 0.01, 0.02, 0.05, 0.1, 1. The tumor heterogeneity emerges when noise strength becomes large where the four types of cells are almost equally distributed.
