Multiple PANC-1 cells within the scaffolds expressed both pan-Cytokeratin and CD-24 cellular markers (Figure 5, middle panels), highlighting the heterogeneous nature of the cancer cell population for the PANC-1 cell line (Schüssler et al., 1992; Aghamaliyev et al., 2015; Pei et al., 2016; Haeberle and Esposito, 2019). The gene discussed is CD24; the disease is cancer.
