Figure 3. Electron microscopy reveals phloretin and pimaric acid cause the swelling of the mitochondria and the endoplasmic reticulum.

Figure 3

T9 cells were incubated without any BK channel activators (Panel A); 1 hour with 0.01 mM pimaric acid (Panel C); 1 hour with 1 mM phloretin (Panels B and D). All magnifications are 15,000×, except Panel D which was 30,000×. The white arrows indicate the mitochondria, while the black arrows show the endoplasmic reticulum.
