The distal convoluted tubule has simple cuboidal epithelium with only a sparse brush border of microvilli. The proximal convoluted tubule, on the other hand, has a more prominent brush border of microvilli. The ascending and descending limbs of the nephron loop do not have a brush border, and the collecting duct is lined with principal cells and intercalated cells, which have different types of epithelium.
