Multiple cellular pathways regulate lipid droplet homeostasis for the establishment of polarity in collagen sandwich-cultured hepatocytes

Hepatocyte polarization is energy dependent. The establishment of polarization in collagen sandwich culture of hepatocytes requires utilization of lipid droplets and mitochondrial β-oxidation to supply ATP. Multiple cellular pathways are involved in lipid droplet homeostasis; however, mechanistic insights of how hepatocytes utilize lipid droplets during polarization remain elusive. The current study investigated the effects of various pathways...
