Microvilli, Brush Border-Duodenum
The cell surfaces of resorptive cells feature a dense cover of microvilli. The microvilli extend upward from the surface and create a pattern, which can be recognize d in light microscopy as a light, stripe d border, the brush border 1 . It is PAS-positive and contains several marker enzymes, which partake in resorptive cell activities. The figure shows Pseudostratified columnar epithelial surface cells from a small intestinal crypt. Goblet cells 2 , filled with secretor y products, exist side by side with the epithelial cells.
