For example, CD36 is coexpressed with the stemness markers CD44+/CD133+/ALDH+ in breast cancer (Gyamfi et al., 2021), with CD44bright in OSCC (Pascual et al., 2017), and with CD44+/CD133+/ITGA6+ in GBM (Hale et al., 2014; Erhart et al., 2019). This evidence concerns the gene CD44 and breast cancer.
