The final stages of cell division is captured in the scanning electron micrograph. Two daughter cells are still interconnected by slender strands of membrane (white arrow at center of image). Lamellipodia extend from the periphery of each new cell as they begin to spread on the substrate, and microvilli stud the surface over the nucleus. The funnel-like cones (black arrows) are candidate sites for pinocytosis.
