Indicating the six different experimental groups as well as the three subgroups in each experimental group, according to the number and route of transplantation of ADSCs and the postoperative day of euthanasia. ¹POD: postoperative day; ²ADSCs: adipose tissue stem cells; ³PV: portal vein; ⁴HP: hepatic parenchyma.
