Apart from these surface markers, one of the top differentially expressed genes is thymosin beta 4 (TMSB4X), which is associated with the stemness and differentiation of progenitor and cancer cells (Fig. 4D; Table S1) (Bock-Marquette et al., 2009; Lv et al., 2013; Wirsching et al., 2013). Here, TMSB4X is linked to cancer.
