Figure 4: Scanning electron micrograph of OVCA 432 (a) and A2780 (b). It’s evident the enormous release of microvesicles with heterogeneous dimensions ranged between 300–100 nm. (a) The microvesicles shedding is visible on whole cell body in OVCA 432; (b) the phenomenon is more evident at the edge of cells (personal original unpublished data).
