Electron micrograph of dividing goblet cells. This electron micrograph demonstrates that certain cells of the intestine continue to divide even after they have differentiated. Here, two goblet cells (GC) are shown in division. Typically, the dividing cells move away from the basal lamina toward the lumen. One of the goblet cells shows mu-cinogen granules (M) in its apical cytoplasm. The chromosomes (C) of the dividing cells are not surrounded by a nuclear membrane. Compare with the nuclei (IM) of the nondividing intestinal epithelial cells. The lumen of the gland (L) is on the right. CT, connective tissue; and E, eosinophil, x 5,000.
