To further explore cellular heterogeneity in rasV12scrib-/- tumors, we performed a sub-clustering analysis and detected four tumor subpopulations, delimited by the expression gradient of several markers of wound β and C/EBP targets genes such as Gadd45 and CG13024 (Figure 4—figure supplement 2, Supplementary file 5). The gene discussed is CEBPA; the disease is neoplasm.
