    Spleen - Hyperplasia, Plasma cell in a female B6C3F1/N mouse from a chronic study (higher magnification of Figure 1). Plasma cells (arrow) are round to oval with a high nucleus-to-cytoplasm ratio, typically eccentric nucleus with heterochromatin in a characteristic cartwheel or clock face arrangement, and a pale perinuclear region with a Golgi apparatus.
