The small intestine absorbs lipophilic molecules and transports them in triglyceride-rich lipoproteins. We recently developed a cell-based model capable of producing these lipoproteins. The secreted lipoproteins, namely chylomicrons and very lowdensity lipoproteins, were isolated by NaCl gradient ultracentrifugation. Their triglycerides, apolipoprotein B, and particle size distribution were subsequently analyzed by enzymatic assay, ELISA/Western blot, and transmission electron microscopy, respectively. Our analysis showed that 21% of the total number of secreted lipoproteins were chylomicrons. Most of the chylomicrons had a diameter of 80-200 nm, and they contained both apolipoprotein B-48 and B-100. In addition, we were able to utilize lentivirus expression system, which is more effective than the regular transfection methods, in upregulating gene expression. Our newly developed model/assay can potentially be used to study dietary fat absorption, chylomicron biogenesis, oral lipophilic drug bioavailability, and intestinal transport of lipophilic molecules.
