Xenotransplantation of human pancreatic cancer cells into ZZU001 Syrian hamsters recapitulates human pancreatic cancer metastasis. A: Growth curve of human MIA-PaCa-2 pancreatic cancer cells in ZZU01 Syrian hamsters and B-NDG mice. MIAPaCa-2 cells were subcutaneously inoculated into the flank of ZUU001 and B-NDG mice (n = 5/group). Tumors were measured twice weekly and the tumor volume estimated. Mean tumor size ± standard error of the mean is shown. ns: no significance; B: A representative hematoxylin and eosin (HE) stained section of a kidney and adrenal gland with metastatic tumor at the end of the experiment in ZZU001 hamsters (56 d) and B-NDG mice (42 d); C: Representative HE staining of a lung metastasis at 22 d, 29 d, 36 d after the injection of MIA-PaCa-2 cells in ZZU001 hamsters and B-NDG mice; D: Representative HE, Masson, smooth muscle actin (SMA) and vimentin staining of a subcutaneous tumor at 42 d after the injection of the MIA-PaCa-2 cells in ZZU001 hamsters and B-NDG mice. Scale bars = 100 µm.
