Extended Data Fig. 9: Analysis of the impact of TP53 mutations in non-cancerous MMNK1 cells.

We introduced various TP53 mutations to MMNK1 cells using CRISPR base editors and subsequently cultured the cells under media containing nutlin-3a. Analysis of the resulting population revealed no growth advantage for cells with TP53 mutations compared to wild-type cells. N = 2 biologically independent cells. P = 0.14, 0.85, 0.78, 0.34; two-sided t-test.
