CD271+ Subpopulation of Pancreatic Stellate Cells Correlates with Prognosis of Pancreatic Cancer and Is Regulated by Interaction with Cancer Cells
Figure 5
Expression of α-smooth muscle actin (SMA)+ and CD271+ stromal cells during in vivo tumor growth of pancreatic cancer.
(A) α-SMA+ stromal cells, as activated PSCs, exist in the xenograft tumor and normal pancreas (NP) areas (left side) around the tumor (right side). (B) Few CD271+ stromal cells were present in the NP area (left side) around the xenograft tumor, and were absent in the tumor core (right side). Original magnification: 200×.
