Interleukin-8, a promising predictor for prognosis of pancreatic cancer

Figure 2 Histology of human pancreatic cancer tissue and transplanted tumor in SCID mice. A: Both vascular (arrow) and neural invasion (cross) were seen in the original human pancreatic ductal adenocarcinoma (PDC) (× 100); B: Cancer cells were infiltrating the medium-sized vessel in human PDC tissues (× 100) (arrow). Desmoplastic response was obvious in the human PDC tissues; C, D: Transplanted cancer tissue in SCID mice in low power (C, × 40) and in high power (D, × 200). Cancer cells were almost clustered and poorly differentiated. In some areas, primitive gland formation could be seen (arrow). Cells grew into sheet with very less stromal reaction than the original human tissues.
