Tumor cells isolated from OV tissues were reclustered into four distinct subpopulations (Figure 5), and their differentiation potentials were assessed using cytoTRACE. Bubble plots of EFNA1 and SCNN1A expression levels demonstrated that tumor cells 0 and 1, which exhibited higher differentiation potential, had higher expression of these genes (Figure 5). Here, EFNA1 is linked to neoplasm.
