Fig. 1From: Induction of tolerogenic dendritic cells by activated TGF-β/Akt/Smad2 signaling in RIG-I-deficient stemness-high human liver cancer cellsTumorsphere formation is enhanced by RIG-I KD. RIG-I knocked-down cells (CRIG-Ish1 and CRIG-Ish2) and controls (NC and NCsh) of SMMC-7721 and Bel-7402 cell lines were grown in 96-well ultra-low attachment culture plates for 10 days. The tumorspheres formed were observed under a microscope. Scale bars, 100 μmBack to article page
