Lipid droplet quantity is increased upon CPO expression.

A) The number of lipid droplets per 100 μm2 of cell area was counted in stably-transfected MDCK cells. Each sample included at least 10 fields of view from two separate experiments and is presented as the median value in a box and whisker plot. Cell area was determined using ImageJ. B) Transiently-transfected MDCK cells were compared with untransfected neighboring cells at 12 hours after transfection. * p p p t test in comparisons of cells expressing active CPO and control.
