(A) Cell’s growth rate of the Huh7-P, Huh7-C, and Huh7-S cells (*P<0.05); (B) Cell’s growth rate of SMMC-7721-P, SMMC-7721-C, and SMMC-7721-S (*P<0.05); (C) The cell cycle distribution and the proliferous indexes of Huh7-P, Huh7-C, and Huh7-S cells; (D) The cell cycle distribution and the proliferous indexes of SMMC-7721-P, SMMC-7721-C, and SMMC-7721-S cells; (E) Colony numbers of Huh7-P, Huh7-C, and Huh7-S cells (*P<0.05; NS, no significant difference); (F) Colony numbers of SMMC-7721-P, SMMC-7721-C, and SMMC-7721-S cells (*P<0.05; NS, no significant difference).
