Figure 1616

Photomicrograph of a dividing cell in the isthmus of a pyloric gland.

The gastric pits in this photomicrograph were sectioned in a plane that is oblique to the axis of the pit. Note that on this section, gastric pits (arrows) can be recognized as invaginations of surface epithelium that are surrounded by lamina propria. The lamina propria is highly cellular because of the presence of large numbers of lymphocytes. x240. Inset. This high magnification of the area indicated by the rectangle shows a dividing cell in the isthmus. x580.
