Background:

Customized, patient-specific scaffolds offer significant potential for treating large tissue defects.
Transitioning modestly sized tissue engineering solutions to clinical use is progressing, but scaling up to large, anatomically accurate scaffolds remains a challenge.
Conflicting requirements for cell placement, structural integrity, and a supportive hydrodynamic environment complicate the development of large scaffolds.

Purpose of the Study:

To review technologies and methods for designing and manufacturing large, anatomically accurate tissue-engineered scaffolds.
To focus on the interaction between manufactured scaffolds and the dynamic tissue culture fluid environment.

Main Methods:

Exploration of various manufacturing techniques for large-scale scaffold production.
Review of culturing and characterization methods for tissue-engineered scaffolds.
Analysis of scaffold behavior within a dynamic hydrodynamic environment relevant to cell culture.

Main Results:

Identification of key challenges in producing large, patient-specific scaffolds.
Discussion of technologies that address the integration of cell placement, structural integrity, and fluid dynamics.
Highlighting the importance of understanding scaffold-tissue fluid interactions for successful tissue engineering.

Conclusions:

Continued development of advanced manufacturing and culturing techniques is crucial for large scaffold fabrication.
Optimizing the interaction between scaffolds and the dynamic culture environment is essential for clinical translation.
This review provides insights into overcoming hurdles in creating functional, large-scale tissue-engineered constructs.
