Biological Cell or Tissue Cross-Section Diagram - Medical Illustration #3502714 (License: Personal Use)

This vector illustration depicts a spherical biological entity-possibly a glandular acinus, follicle, or engineered tissue construct-with a porous outer shell, a dense network of fibrous stroma in the middle layer, and a compact red central region suggesting vascularization or high metabolic activity. The clean, schematic style emphasizes structural organization over photorealism, making it ideal for teaching histology or tissue engineering concepts.

Used in educational platforms, medical textbooks, or biomedical websites to explain tissue architecture, organ microstructure, or scaffold design in regenerative medicine; targets students, clinicians, and researchers seeking visual reinforcement of anatomical or physiological principles.
