Establishment and characterization of a new human ampullary carcinoma cell line, DPC-X1

Figure 3 Ultrastructure of DPC-X1 under a transmission electron microscope. A: DPC-X1 has a large and deformed nucleus; it is increased in number. The nucleolus is clustered in the nuclear membrane. There are fewer cytoplasm. Microvilli (yellow arrow) and pseudopodia (blue arrow) were visible on the cell surface; B: DPC-X1 cells are rich in the endoplasmic reticulum (yellow arrow) and ribosome; C: DPC-X1 cells have well-developed Golgi apparatus (yellow arrow), and the size and shape of the mitochondria are different (blue arrow); D: DPC-X1 desmosome structure can be seen between the cells (arrow).
