headline: Reproducibility and Validation Challenges in AI-Driven Scaffold Design for Bone Regeneration
dek: Artificial intelligence (AI) is increasingly applied to bioink formulation and bioprinting process control in tissue engineering (TE). Yet, translational progress remains constrained by small datasets, limited cross-platform validation, and weak links between computational predictions and biological outcomes. This review critically evaluates experimentally validated AI applications across scaffold-based bone regeneration, spanning materials design, fabrication control, and biological assessment. Physics-informed…

quick_read: By July 10 2026, a peer-reviewed review in Tissue Engineering Part B: Reviews evaluated experimentally validated AI uses in scaffold-based bone regeneration, from materials design to fabrication control and biological assessment. It reported that physics-informed models tend to be more robust and generalizable than purely data-driven models, while transfer learning is hampered by variability in cellular responses and fabrication conditions.

The findings matter because weak links between computational predictions and biological outcomes, combined with small datasets and limited cross-platform validation, limit reliability and translational relevance for bone repair. The authors propose an AI-TE reporting framework to improve biological validation and documentation, but uncertainty remains about how consistently these standards will be adopted and whether they will close the gap to clinical translation.
limitation: Translational claims are limited by small datasets, limited cross-platform validation, and weak links between computational predictions and biological outcomes, with reproducibility and validation insufficiently addressed.

key_points: Review evaluates experimentally validated AI applications across scaffold-based bone regeneration covering materials design, fabrication control, and biological assessment. | Physics-informed models show greater robustness and generalizability than purely data-driven models. | Transfer learning remains difficult due to variability in cellular responses and fabrication conditions.
rundown: The review spans materials design, fabrication control, and biological assessment for scaffold-based bone regeneration, noting that AI is increasingly applied to bioink formulation and bioprinting process control.

It contrasts modeling approaches, finding physics-informed models more robust and generalizable, while transfer learning remains challenging due to variability in cellular responses and fabrication conditions.

To address reporting gaps, the authors propose the AI-TE reporting framework incorporating requirements for biological validation, fabrication documentation, and translational readiness.
