In tissue engineering, it is crucial to recognize that cells do not function in isolation; they require a suitable environment that mimics the natural conditions of tissues. Simply harvesting cells and placing them in a designed pattern overlooks the complexity of tissue behavior.

Cells need structural, mechanical, and chemical cues to survive, grow, and differentiate appropriately. Structural cues may include extracellular matrix components that provide support and guide cell behavior. Mechanical cues involve the physical forces and stiffness of the tissue that can influence how cells respond and interact. Additionally, chemical cues, like growth factors and signaling molecules, are essential for cellular communication, influencing processes such as proliferation and differentiation.

Therefore, it is essential to provide a comprehensive environment that includes all these cues, rather than just arranging cells spatially. This ensures the engineered tissue can function effectively once implanted, ultimately leading to successful outcomes in regenerative medicine.
