  • Pencil drawing of two diseased and a healthy enterocyte. Different cellular structures are shaded in different colors. Most important are the microvilli. The healthy enterocyte shows tall, brush border microvilli (green) pointing up and tipped with orange. There are a few speckles of orange throughout the cell (“secretory granules”). The diseased enterocytes show very few microvilli on the apical surface of the cells, and, where present, are shorter than in the healthy cell. There is a lot more orange in the diseased cells. The MVID cells also have clumps of microvilli on the inside.

    Help! Microvilli trapped inside cells!
