Such networks allow cells to hold — and move — specialized shapes, such as the brush border of microvilli. Actin filaments are also involved in cytokinesis and cell movement (Figure 3).

I guessed anywhere from 10 to 100 years. Figure 2: In this example, a piece of intestine is cut out (1), and brush-border epithelial cells are dissociated to use them for nuclear transfer (2).
