Wild-type mice at 9 weeks of age intraperitoneally received a CCl4 solution twice a week for 4 weeks. The CCl4 solution was freshly prepared CCl4 (0.5 mg/kg in olive oil [Wako Pure Chemicals]; CCl4:olive oil = 1:4 volume/volume). The 4-week-CCl4-treated mice received each donor-derived hDPSC products (0.1 × 106/10 g body weight in PBS) via the spleen [26 (link)]. The hDPSC-transplanted mice were subsequently treated with CCl4. The age-matched mice that received olive oil and sham-operated CCl4 were used as negative and positive controls.
