Fig. 1From: A new pathological classification of intrahepatic cholangiocarcinoma according to protein expression of SSTR2 and Bcl2Immunostaining of IHCC tumor tissue for SSTR2 and Bcl2. a Expression of SSTR2 was only observed in the cell membrane of the cancer cells (× 200 magnification). b Expression of Bcl2 was observed in the cytoplasm of the cancer cells (× 200 magnification). c Expression of SSTR2 was observed in the normal large bile duct (× 200 magnification). d Expression of Bcl2 was observed in the normal small bile duct including bile ductule (× 200 magnification). IHCC: intrahepatic cholangiocarcinoma, SSTR2: somatostatin receptor 2, Bcl2: b cell leukemia/lymphoma 2Back to article page
