This image shows a colorized scanning electron micrograph (SEM) of a lung cancer cell.

Spiky Extensions (Filopodia & Invadopodia): The elongated, hair-like projections radiating outward allow the cancer cell to anchor itself to surrounding surfaces, move, and invade neighboring healthy tissues.

Surface Blebs: The spherical, bubble-like bumps covering the central body of the cell are known as blebs. These form due to decoupling of the cell membrane from the internal cytoskeleton and are highly characteristic of dynamic membrane activity during cell movement, division, or stress.

Microvilli: The dense, fine texture on the main body represents microvilli, which significantly increases the cell's surface area, aiding in nutrient absorption and environmental signaling.

This image is an immunofluorescent micrograph showing the intestinal epithelium.Proliferating Cells: The red-stained cells are proliferating cells, which are actively dividing to repair damage or renew the tissue.Intestinal Stem Cells: The bright green cells at the base of the crypts represent the stem cell compartment, which gives rise to new epithelial cells.Cell Nuclei: The blue staining highlights the nuclei of all cells within the tissue.Tissue Function: This specific view of the intestinal tract highlights the dynamic process of cell renewal and repair, which is critical for absorbing nutrients and defending against pathogens.
