Facts (generated by robot; please edit if you find it inaccurate)

• Villin-induced growth of microvilli is reversibly inhibited by cytochalasin D.
• The actin core of the microvilli is not clearly visible in this picture.
• As a function of time and temperature, this initial preferential localization to microvilli is lost, and the ligand is internalized by the cell.
• The widely accepted view is that the principal function of the microvilli is to greatly increase the surface area for water and solute exchange in the kidney and enzymatic digestion in the small intestine.
• The primary component of microvilli is actin filaments, which are also found in microtubules.
