In addition, we evaluate the ability of PDCs to differentiate into osteocytes, chondrocytes, and adipocytes. Biology Using Caco-2 Cells to Study Lipid Transport by the Intestine Andromeda M. Nauli1, Judy D. Whittimore2 1Department of Pharmaceutical and Biomedical Sciences, College of Pharmacy, California Northstate University, 2Department of Biomedical Sciences, James H. Quillen College of Medicine, East Tennessee State University Caco-2 cells can serve as an in vitro model to study the enterocyte transport of lipids, and lipid-soluble drugs/vitamins. The permeable membrane system separates the apical from the basolateral compartment, while the lentivirus expression system offers an effective gene overexpression method. The isolation of lipoproteins is confirmed by TEM.

The goal of this protocol was to integrate the native environmental sample into a cell culture format assessing the changes in toxicity due to CuO-NP treatment.
