Fig. 1From: Endothelial cell-specific molecule-1 as an invasiveness marker for pituitary null cell adenomaa Strong endothelial cell-specific molecule-1 (ESM-1) index was seen in the cytoplasm of vascular endothelial cells, and weak ESM-1 index was seen in the cytoplasm of adenoma cells; b intermediate ESM-1 index was seen in the cytoplasm of vascular endothelial cells, and weak ESM-1 index was seen in the cytoplasm of adenoma cells; c weak ESM-1 index was seen in the cytoplasm of vascular endothelial cells, and intermediate ESM-1 index was seen in the cytoplasm of adenoma cells; d both intermediate ESM-1 index was seen in the cytoplasm of vascular endothelial and adenoma cells.
