Formation of altered TF antigen in ESCC Golgi apparatus. A Electron micrograph of normal squamous cell showing weak TF antigen expression (Uranyl acetate and lead citrate staining. Bar scale = 200 nm). B. Electron micrograph of neoplastic squamous cell of the cisternae of Golgi apparatus showing abundant gold labeling for increased TF antigen (Uranyl acetate and lead citrate staining. Bar scale = 500 nm).
