Microblebs of intestinal epithelial cell microvilli of Citellus tridecemlineatus

The presence of microblebs arising from the lateral surfaces and tips of microvilli of intestinal epithelial cells of thirteen-lined ground squirrels. Citellus tridecemlineatus, is reported. Microblebs measure approximately 50 nm in diameter and are bounded by a unit membrane which is continuous with the unit plasma membrane of the microvilli. It is suggested that such microblebbing reflects the rapid turnover of microvillar contents, membrane and surface coat.
