Synthesis and transport of lipoprotein particles by intestinal absorptive cells in man

Abstract

The site of synthesis and some new details of lipoprotein particle transport have been demonstrated within the jejunal mucosa of man. In normal fasting volunteers, lipoprotein particles (88%, 150-650 A diameter) were visualized within the smooth endoplasmic reticulum and Golgi cisternae of absorptive cells covering the tips of jejunal villi. Electron microscopic observations suggested that these particles exited through the sides and bases of absorptive cells by reverse pinocytosis and then passed through the extracellular matrix of the lamina propria to enter lacteal lumina.
