TGFB1 and bladder transitional cell carcinoma: By displaying the expression level of TS-related genes and performing differential analysis and correlation analysis of the TS score and stem cell gene set ssGSEA score, we found that TGF-β could improve the stemness and TS score of BLCA and further validated that the TS score could reflect the EMT process and stemness of BLCA (Fig. 8C-8F).
