FIG. 7.
Secreted OPN has limited effect on CSC proliferation and progression to HCC. (A) Experimental approach to study the effect of rOPN on primary hepatocytes and CSCs (n = 3/group). (B‐D) Experimental approach to study the role of extracellular OPN on CSC progression to cancer, representative gross appearance of the livers, and number of tumors in both groups (mean ± SEM). (E) Representative gross appearance of livers from Cd44 −/− (n = 14) and Cd44 −/− Opn Hep Tg (n = 14) mice injected with DEN and sacrificed 12 months later. (F) Number of macroscopic tumors per mouse liver (mean ± SEM).
