SELENOP and cancer: Moreover, in ASCs and MSS cancer cells, SELENOP expression was weakly correlated (r = 0.44, P = 0.01) with inferred stemness, as derived from Cellular Trajectory Reconstruction Analysis Using Gene Counts and Expression (CytoTRACE) analysis that computationally predicts cellular differentiation states from scRNA-Seq data (28) (Figure 2B).
