Background:

• Traditional two-dimensional (2D) cell culture lacks in vivo physiological relevance.
• Cells cultured in 2D on plastic surfaces do not accurately mimic the complex cellular environment.
• There is a need for more advanced cell culture models that better represent in vivo conditions.

Purpose of the Study:

• To highlight the advantages of three-dimensional (3D) cell culture over 2D models.
• To demonstrate the enhanced physiological relevance of cells cultured in 3D environments.
• To showcase the improvements in studying various biological mechanisms using 3D cell culture.

Main Methods:

• Utilizing artificial environments that allow cells to grow and interact in all three dimensions.
• Implementing technological advancements in materials science, cell biology, and bioreactor design.
• Culturing cells in a manner that mimics their natural three-dimensional in vivo state.

Main Results:

• Cells grown in 3D models exhibit greater physiological relevance compared to 2D cultures.
• Significant improvements observed in monitoring cell number, viability, and morphology.
• Enhanced understanding of proliferation, differentiation, and response to stimuli in 3D.
• More accurate modeling of tumor cell migration, invasion, angiogenesis, and immune system evasion.
• Improved studies on drug metabolism, gene expression, protein synthesis, and overall cell function.
• Demonstrated increased in vivo relevance of findings from 3D cell cultures.

Conclusions:
